RI.7.5: Analyzing Text Structure and How Sections Build Ideas
In plain English: RI.7.5 is the Common Core grade 7 ELA standard that asks students to analyze the structure an author uses to organize an informational text. Students go beyond naming the structure: they explain how each major section contributes to the whole text and to the development of its ideas. It builds on RI.6.5.
Analyze the structure an author uses to organize a text, including how the major sections contribute to the whole and to the development of the ideas.
Common Core State Standards for English Language Arts & Literacy · Domain: Reading Standards for Informational Text · Cluster: Craft and Structure · Official standard
Students learn to analyze the structure of an informational text: the way an author organizes it into parts and puts those parts in order. RI.7.5 asks for more than a label such as "chronological." Students break a text into its major sections (the large parts that each do one job), explain how each section contributes to the whole, and trace how the ideas develop, or grow and change, from one section to the next.
The main text is "In the Laboratory with Agassiz" (1874), a short true account by the scientist Samuel H. Scudder, reprinted in Lane Cooper's Louis Agassiz as a Teacher (1917). As a young student, Scudder was handed an old fish in a jar and told to look at it, and then to look again, for days. The account is told in time order, but its sections are carefully built: each stage of the lesson changes what Scudder sees and what he thinks looking means. The homework adds a short letter by another of Agassiz's students, Addison Emery Verrill, organized in a very different way, and an invented article about a school bike rack opens the lesson with a third kind of structure.
Learning Objectives
By the end of this lesson, students will be able to:
Identify the overall structure of an informational text and the signal words that show it
Divide a text into its major sections and name the job each section does
Explain how a major section contributes to the whole text, including what the text would lose without it
Trace how an idea develops from one section to the next, citing a sentence from each section
Explain why an author might break time order or place a reflection at a certain point
Prior Knowledge Required
Students should already be comfortable with:
Analyzing how a sentence, paragraph or section fits into the overall structure of a text RI.6.5
Determining a central idea of a text and the details that convey it RI.6.2
Recognizing transition words such as first, then, because and however
Citing a text with quotation marks and a paragraph number
"Read the short article below. Give each of its four paragraphs a label of one or two words that names its job. Then decide: what would a reader miss if paragraph 2 were cut?"
1Every school morning last fall, about 60 students rode bikes to Hillview Middle School, but the rack by the front door held only 24 bikes. Late riders locked their bikes to the fence, the flagpole and even the stair railing, and on rainy days the front hallway filled with wet tires.
2The seventh-grade student council decided to find out why the problem kept growing. A survey of 120 students showed that many had started riding after the city painted a new bike lane on Oak Street in September.
3The council tried two fixes. First, they asked riders to park bikes head to tail, which fit only four more bikes. Then they wrote a letter to the principal and the parent club asking for a second rack beside the gym.
4In January, the parent club paid for a 40-bike rack. Now every bike has a spot, the railing is clear, and the council has a new goal: a roof over both racks before next winter.
Written for this page, The Bike Rack Problem (an invented article for the warm-up and Activity 3). Original passage written for this page.
Collect labels on the board. Students usually arrive at something like problem, cause, fixes, result. Tell them this is a structure: the plan an author uses to organize a text. Each paragraph here is also a section, a part of the text with one job. Then ask about paragraph 2. Without it, the article still makes sense, but the reader never learns why there were suddenly too many bikes, so the fixes in paragraph 3 look like guesses instead of a plan. That is the question RI.7.5 asks about every section: what does it add to the whole, and what would the reader lose without it?
Direct Instruction15 minutes
Teach six terms and leave them on the board:
Structure: the way an author organizes a whole text. Common structures are chronological (time order), compare and contrast, cause and effect, problem and solution, and claim and examples (Diagram 2).
Major section: a large part of a text that does one job. A section can be one paragraph or several; in a text without headings, look for a change in time, place, topic or purpose.
Signal words: transitions that show how parts connect, such as "the next morning" (time), "because" (cause) or "for example" (an example).
Contribute to the whole: what a section adds that the text needs. Test it by imagining the text without that section.
Development of ideas: how an idea grows or changes from section to section, for example from a simple belief to a deeper one.
Reflection: a moment when the writer steps outside the events to say what they mean.
Introduce the text. Louis Agassiz (1807-1873) was a Swiss-born scientist who taught at Harvard University and started its Museum of Comparative Zoology. Samuel H. Scudder (1837-1911) arrived in his laboratory in the late 1850s wanting to study insects, and he later became a leading American expert on them. In 1874, the year after Agassiz died, Scudder wrote this account of his first days as a student. Words to know for Passage 1: laboratory (a room for scientific work), natural history (the study of plants and animals), antecedents (background), zoology (the study of animals), purposed (intended), specimens (animals or plants kept for study), haemulon (a kind of fish, often called a grunt), explicit (clear and exact), naturalist (a scientist who studies nature), stoppers and corks (plugs for jars), begrimed (made dirty), entomology (the study of insects), ichthyology (the study of fishes), infectious (catching, spreading to others), aversion (dislike), sacred precincts (holy grounds; Scudder is joking), commend itself (appeal), ardent (eager) and eau-de-Cologne (a perfume). "A very ancient and fishlike smell" is a line from Shakespeare's play The Tempest.
1It was more than fifteen years ago [from 1874] that I entered the laboratory of Professor Agassiz, and told him I had enrolled my name in the Scientific School as a student of natural history. He asked me a few questions about my object in coming, my antecedents generally, the mode in which I afterwards proposed to use the knowledge I might acquire, and, finally, whether I wished to study any special branch. To the latter I replied that, while I wished to be well grounded in all departments of zoology, I purposed to devote myself specially to insects.
2'When do you wish to begin?' he asked.
3'Now,' I replied.
4This seemed to please him, and with an energetic 'Very well!' he reached from a shelf a huge jar of specimens in yellow alcohol.
5'Take this fish,' said he, 'and look at it; we call it a haemulon; by and by I will ask what you have seen.'
6With that he left me, but in a moment returned with explicit instructions as to the care of the object entrusted to me.
7'No man is fit to be a naturalist,' said he, 'who does not know how to take care of specimens.'
8I was to keep the fish before me in a tin tray, and occasionally moisten the surface with alcohol from the jar, always taking care to replace the stopper tightly. Those were not the days of ground-glass stoppers and elegantly shaped exhibition jars; all the old students will recall the huge neckless glass bottles with their leaky, wax-besmeared corks, half eaten by insects, and begrimed with cellar dust. Entomology was a cleaner science than ichthyology, but the example of the Professor, who had unhesitatingly plunged to the bottom of the jar to produce the fish, was infectious; and though this alcohol had 'a very ancient and fishlike smell,' I really dared not show any aversion within these sacred precincts, and treated the alcohol as though it were pure water. Still I was conscious of a passing feeling of disappointment, for gazing at a fish did not commend itself to an ardent entomologist. My friends at home, too, were annoyed, when they discovered that no amount of eau-de-Cologne would drown the perfume which haunted me like a shadow.

Overall structure: chronological order
Passage 1 moves from Scudder's arrival (paragraph 1) to the question "'When do you wish to begin?'" and his answer "'Now,'" to the jar of specimens, to Agassiz leaving and coming back "in a moment." How is the account organized, and what signals it?
Result: The account is chronological: it tells the lesson in the order it happened. The signals are small time moves between paragraphs: the question and the answer, "With that he left me," "in a moment returned." Naming the structure is only step one; RI.7.5 then asks what each part does.
The job of a section: setting a starting point
Paragraph 8 ends Passage 1: "gazing at a fish did not commend itself to an ardent entomologist," and the smell "haunted me like a shadow." What does this paragraph contribute to the whole account?
Result: It sets a starting point. Scudder wants to study insects, the fish smells, and he is disappointed. A reader who knows where he starts can measure every later change in his attitude. Without this paragraph, the account would lose the before in its before-and-after.
How a section begins an idea
In paragraph 7, Agassiz says, "'No man is fit to be a naturalist,' said he, 'who does not know how to take care of specimens.'" What idea does Section 1 begin to develop?
Result: The first section introduces the idea that becoming a scientist is a discipline, not a quick look: it starts with patient care for one object. Scudder does not yet know what the fish will teach him, and neither does the reader. The later sections build on this idea step by step.
A different structure: problem and solution
The bike rack article (warm-up) has four paragraphs: too many bikes, a survey that finds the cause, two fixes, and a new rack. How does its order develop its idea?
Result: The structure is problem and solution, with a cause section in the middle. The order makes the idea clear: the council solved the problem because it studied the cause first. Moving the new rack to the first paragraph would give away the ending and hide how the students worked it out.
Structure, section, contribution, development. Show Diagram 1, the structure map, and fill in the first box of the bottom row together. Model the four moves: name the structure, mark where each section starts, say what the section adds to the whole, and say how the idea has changed by the end of it. Give students one sentence frame: "Section ___ (paragraphs ___) shows ___. Without it, the reader would not know ___, and the idea that ___ would not develop." Keep Diagram 2 posted as a reference for signal words.
Guided Practice15 minutes
Read Passages 2 and 3 aloud. They follow Passage 1 directly. Words to know: resuscitate (bring back to life), fainting-fit (a faint), steadfast (steady), mute (silent), loathsome and hideous (disgusting, ugly), ghastly (horrible), despair (loss of hope), interdicted (forbidden), rehearsal (retelling), gill-arches (the curved bones that hold a fish's gills), operculum (the flap that covers the gills), lateral line (a line of sense organs along a fish's side), spinous (spiny), compressed (flattened), conspicuous (easy to notice), piqued (annoyed), mortified (embarrassed), with a will (with determination), just (fair), disconcerting (upsetting), perplexities (puzzles) and distracted (unable to think clearly).
1In ten minutes I had seen all that could be seen in that fish, and started in search of the Professor--who had, however, left the Museum; and when I returned, after lingering over some of the odd animals stored in the upper apartment, my specimen was dry all over. I dashed the fluid over the fish as if to resuscitate the beast from a fainting-fit, and looked with anxiety for a return of the normal sloppy appearance. This little excitement over, nothing was to be done but to return to a steadfast gaze at my mute companion. Half an hour passed--an hour--another hour; the fish began to look loathsome. I turned it over and around; looked it in the face--ghastly, from behind, beneath, above, sideways, at a three-quarters' view--just as ghastly. I was in despair; at an early hour I concluded that lunch was necessary; so, with infinite relief, the fish was carefully replaced in the jar, and for an hour I was free.
2On my return, I learned that Professor Agassiz had been at the Museum, but had gone, and would not return for several hours. My fellow-students were too busy to be disturbed by continued conversation. Slowly I drew forth that hideous fish, and with a feeling of desperation again looked at it. I might not use a magnifying-glass; instruments of all kinds were interdicted. My two hands, my two eyes, and the fish: it seemed a most limited field. I pushed my finger down its throat to feel how sharp the teeth were. I began to count the scales in the different rows, until I was convinced that that was nonsense. At last a happy thought struck me--I would draw the fish; and now with surprise I began to discover new features in the creature. Just then the Professor returned.
3'That is right,' said he; 'a pencil is one of the best of eyes. I am glad to notice, too, that you keep your specimen wet, and your bottle corked.'

1With these encouraging words, he added:
2'Well, what is it like?'
3He listened attentively to my brief rehearsal of the structure of parts whose names were still unknown to me: the fringed gill-arches and movable operculum; the pores of the head, fleshy lips and lidless eyes; the lateral line, the spinous fins and forked tail; the compressed and arched body. When I had finished, he waited as if expecting more, and then, with an air of disappointment:
4'You have not looked very carefully; why,' he continued more earnestly,' you haven't even seen one of the most conspicuous features of the animal, which is as plainly before your eyes as the fish itself; look again, look again!' and he left me to my misery.
5I was piqued; I was mortified. Still more of that wretched fish! But now I set myself to my task with a will, and discovered one new thing after another, until I saw how just the Professor's criticism had been. The afternoon passed quickly; and when, toward its close, the Professor inquired:
6'Do you see it yet?'
7'No,' I replied, 'I am certain I do not, but I see how little I saw before.'
8'That is next best,' said he, earnestly, 'but I won't hear you now; put away your fish and go home; perhaps you will be ready with a better answer in the morning. I will examine you before you look at the fish.'
9This was disconcerting. Not only must I think of my fish all night, studying, without the object before me, what this unknown but most visible feature might be; but also, without reviewing my new discoveries, I must give an exact account of them the next day. I had a bad memory; so I walked home by Charles River in a distracted state, with my two perplexities.

Pairs work through four questions on the structure map, one at a time. Share the teacher note after pairs have tried:
Where does Section 2 begin, and how do you know? Teacher note: at "In ten minutes I had seen all that could be seen in that fish" (Passage 2, paragraph 1). Agassiz has left, the setting is the same, but the time jumps and a new stage starts: Scudder alone with the fish. The sentence also states a belief that the rest of the section will prove wrong.
What is the turning point of Section 2? Teacher note: "At last a happy thought struck me--I would draw the fish; and now with surprise I began to discover new features in the creature" (paragraph 2). Before it, every sentence is about boredom and disgust; after it, Scudder discovers things. Agassiz's reply, "a pencil is one of the best of eyes" (paragraph 3), names the method.
How does the pace of time change from Section 2 to Section 3, and why? Teacher note: in Section 2, time crawls while Scudder is bored and disgusted ("Half an hour passed--an hour--another hour"). Later, in Section 3, "The afternoon passed quickly." The time signals do more than keep order: their pace shows how his attitude toward the task has changed.
How has the idea of looking changed by the middle of Section 3? Teacher note: Scudder's answer, "'I see how little I saw before'" (paragraph 7), shows a new idea: seeing well starts with knowing what you have missed. In Section 1 looking seemed simple; now it is hard work. Agassiz calls this answer "next best."
Independent Practice15 minutes
Students read Passages 4 and 5 on their own. They follow Passage 3 directly and end the account. Words to know: cordial (warm and friendly), reassuring (comforting), discoursed (talked at length), ventured (dared), devices (plans; "left to my own devices" means left to work alone), catalogue (a list), artificial aid (a tool such as a magnifying glass), injunction (an order), entomological (about insects), subsequent (later), legacy (something handed down), inestimable (too great to measure), outlandish (very strange), mortal combat (a fight to the death), hydra-headed (many-headed, like a monster from Greek myth), grotesque (strange and ugly), bidden (told), resemblances (ways things are alike), legion (a huge number), dissection (cutting an animal open to study it), frame-work (skeleton), exhortation (strong urging), general law (a rule that explains many facts) and reluctance (unwillingness).
1The cordial greeting from the Professor the next morning was reassuring; here was a man who seemed to be quite as anxious as I that I should see for myself what he saw.
2'Do you perhaps mean,' I asked, 'that the fish has symmetrical sides with paired organs?'
3His thoroughly pleased 'Of course! of course!' repaid the wakeful hours of the previous night. After he had discoursed most happily and enthusiastically--as he always did-upon the importance of this point, I ventured to ask what I should do next.
4'Oh, look at your fish!' he said, and left me again to my own devices. In a little more than an hour he returned, and heard my new catalogue.
5'That is good, that is good!' he repeated; 'but that is not all; go on;' and so for three long days he placed that fish before my eyes, forbidding me to look at anything else, or to use any artificial aid. 'Look, look, look,' was his repeated injunction.
6This was the best entomological lesson I ever had--a lesson whose influence has extended to the details of every subsequent study; a legacy the Professor has left to me, as he has left it to many others, of inestimable value, which we could not buy, with which we cannot part.

1A year afterward, some of us were amusing ourselves with chalking outlandish beasts on the Museum blackboard. We drew prancing starfishes; frogs in mortal combat; hydra-headed worms; stately crawfishes, standing on their tails, bearing aloft umbrellas; and grotesque fishes with gaping mouths and staring eyes. The Professor came in shortly after, and was as amused as any at our experiments. He looked at the fishes.
2'Haemulons, every one of them,' he said; 'Mr.---- drew them.'
3True; and to this day, if I attempt a fish, I can draw nothing but haemulons.
4The fourth day, a second fish of the same group was placed beside the first, and I was bidden to point out the resemblances and differences between the two; another and another followed, until the entire family lay before me, and a whole legion of jars covered the table and surrounding shelves; the odor had become a pleasant perfume; and even now, the sight of an old, six-inch, worm-eaten cork brings fragrant memories.
5The whole group of haemulons was thus brought in review; and, whether engaged upon the dissection of the internal organs, the preparation and examination of the bony frame-work, or the description of the various parts, Agassiz's training in the method of observing facts and their orderly arrangement was ever accompanied by the urgent exhortation not to be content with them.
6'Facts are stupid things,' he would say, 'until brought into connection with some general law.'
7At the end of eight months, it was almost with reluctance that I left these friends and turned to insects; but what I had gained by this outside experience has been of greater value than years of later investigation in my favorite groups.

On the handout, students (1) mark every time signal in Passages 4 and 5; (2) find one event that is not told in time order and write the two signal words that show it; (3) draw a line where they think Section 4 ends and Section 5 begins, and write one sentence defending the choice; (4) write one sentence for each passage that begins "This section adds ..." The quiz uses Passages 2-5.
Closure5-10 minutes
Exit ticket: (1) In one sentence, explain the difference between naming a text's structure and analyzing it. (2) Choose one section of Scudder's account and finish the frame: "Without this section, the reader would not know ___."
Teacher note on the text and its people: Scudder wrote this account about fifteen years after the events, so the dialogue is his memory of what was said, not a record. The bracketed words "[from 1874]" in the first sentence were added by the editor, Lane Cooper, to date the story; they are not an omission. The fish was a museum specimen kept in alcohol. Agassiz is honored here as a teacher of observation, but he also held views that science has rejected. He opposed Darwin's theory of evolution, and he promoted polygenism, the false idea that human races had separate origins, which he used to argue that some races were superior to others. These passages do not touch those topics, but students who research him will meet them. The account is often retold as "Look at Your Fish"; students may find other versions online that change or shorten the wording, so they should quote only from the passages on this page.
For homework: students read Passage 6, printed below. It is part of a letter that Addison Emery Verrill (1839-1926), another of Agassiz's students who later taught zoology at Yale, wrote to Lane Cooper for the same book. It describes Agassiz's teaching in a different way. Words to know: methods of instruction (ways of teaching), destitute (completely without), a soft snap (old slang for an easy job), mull over (think about slowly), unfit (not suited), individualistic (fitted to each person), mounted (prepared for display), anatomy (the structure of a body), mutilated (badly damaged), loon (a diving water bird), heron (a tall wading bird), vicinity (the nearby area), incubated (kept warm so they develop), embryos (young animals developing inside eggs) and embryology (the study of embryos). Hyatt is Alpheus Hyatt, a fellow student who became a scientist of fossils.
1In regard to the methods of instruction of Agassiz I must say that so far as I saw and experienced he had no regular or fixed method, except that his plan was to make young students depend on natural objects rather than on statements in books. To that end he treated each one of his new students differently, according to the amount of knowledge and experience that the student had previously acquired, and often in line with what the student had done before. Not infrequently young men came to him who were utterly destitute of any knowledge or ability to study natural science, or zoology in particular, but had an idea that it would be a 'soft snap,' as the boys say. In such cases he often did give them a lot of mixed stuff to mull over, to see what they could do, and also to discourage those that seemed unfit. [...] In fact, his treatment was highly and essentially individualistic.
2In my own case, he questioned me closely as to what I had previously done and learned. He found I had made collections of birds, mammals, plants, etc., and had mounted and identified them for several years, and in that way was not a beginner exactly. [...] He had an idea, of course, that though I had collected and mounted birds, and knew their names and habits, I probably knew little about their anatomy. At any rate the first thing he did was to give me a badly mutilated old loon, from old alcohol, telling me to prepare the skeleton. This I did so well and so quickly that he expressed regret that he had not given me some better bird with unbroken bones. He gave me next a blue heron, but it being spring, I 'went collecting' in the vicinity, following my usual inclination, before breakfast and after laboratory hours, and brought in a number of incubated birds'-eggs. When Agassiz came into the laboratory, I was extracting and preserving the embryos, being interested in embryology. He at once exclaimed that he was delighted, and told me to put aside the skeletons and go right on with collecting and preparing embryo birds, and making drawings, etc. [...]
3In the case of Hyatt, who went there just before I did, I think he was kept working over a lot of mixed fish skeletons, more or less broken, to 'see what he could make of them.' [...] Hyatt, however, had never done anything in zoology or botany before he went to Agassiz and he found it hard to get a beginning, and so lost time. I mention these cases to show how different his methods were in different cases.

Differentiation Strategies
For Struggling Students
Give them the structure map with the section breaks already drawn, so they work only on what each section adds
Let them sort the Activity 1 strips with the passage numbers showing on the back, then turn them over to check
Offer sentence starters: "This section adds ...", "Without it, the reader would not know ...", "By the end of this section, Scudder thinks ..."
For Advanced Students
Ask them to divide the account into three sections instead of five and defend the new divisions with signal words
Have them find two details that appear early in the account and return, changed, near the end, and explain what the pairing does for the structure
Ask them to rewrite the opening of the account so that it begins with the last paragraph, then write a note on what the new order gains and loses
Assessment Guidance
What to Look For
Check that students do more than name the structure. Strong answers mark where a section begins with a signal word or a change in time, name the job the section does, and explain its contribution with an "if it were missing" test. Watch for three weak spots: summarizing a section instead of saying what it adds, treating every paragraph as its own section, and saying an idea "develops" without saying how it has changed. For development, look for two quotations from different sections that show the idea at two stages.

Classroom Activities
3 Activities
1
Rebuild the Account
15 minPairs
Each pair gets an envelope of ten sentence strips, one from each stage of Scudder's account, in mixed order. Pairs put them in the order they appear in the text using only the words on the strips, then check against the passages. Last, they find the one strip that is in text order but not in time order.
The Ten Strips
"The fourth day, a second fish of the same group was placed beside the first"
"In ten minutes I had seen all that could be seen in that fish"
"'When do you wish to begin?' he asked."
"At last a happy thought struck me--I would draw the fish"
"The cordial greeting from the Professor the next morning was reassuring"
"A year afterward, some of us were amusing ourselves with chalking outlandish beasts on the Museum blackboard."
"'Do you see it yet?'"
"At the end of eight months, it was almost with reluctance that I left these friends and turned to insects"
"so for three long days he placed that fish before my eyes"
"I was to keep the fish before me in a tin tray"
Procedure
Pairs lay out the strips and circle every signal word or clue about time before they move any strip
They agree on an order, tape it down, and then check it against Passages 1-5
They find the strip that is out of time order and write the two signal words that prove it
Answer key for the teacher: text order is C, J, B, D, G, E, I, F, A, H. Strip F ("A year afterward") comes before Strip A ("The fourth day") in the text, but it happens after Strip H ("At the end of eight months"). It is the only strip told out of time order
Discussion Questions
Which signal words helped most, and which strips had none?
Why might Scudder have told Strip F where he did instead of at the very end?
If you had to cut the account into five sections, where would the cuts fall?
Modification
For students who need support, give six strips (C, J, B, E, A, H) and add Strip F last.
2
Take Out a Section
15 minGroups of 3-4
Each group gets one section card (one of Passages 1-5) and a sheet of chart paper. The group imagines the account with its section removed and writes what the whole would lose. Groups then post their charts in order and fill in the bottom row of the structure map (Diagram 1) together.
What Each Chart Needs
One quotation from the section that shows its main event
"Without this section, the reader would not know ..."
"Without this section, the idea of looking would ..." (for example, would jump, would stay simple, or would never go further)
One signal word or change in time that marks where the section starts
Procedure
Groups read their section twice: once for events, once for what Scudder thinks or feels about looking
They write the chart in 8 minutes, then post it in section order
The class reads the five charts left to right and names the stages the idea passes through
Model answers for the teacher, Sections 1 and 2 only: without Section 1, the reader would not know that Scudder came to study insects and was disappointed, so the change in him would be invisible; without Section 2, the reader would not see the boredom that makes the drawing discovery matter, and the idea that a tool such as a pencil helps a person see would never appear. For Sections 3-5, check that each chart quotes the section and names both what the reader would lose and how the idea would change
Discussion Questions
Which section could be removed with the smallest loss? Is any section truly unnecessary?
Does the idea change most inside one section or between two sections?
Where would you put a heading if the account had headings, and what would each heading say?
3
Same Facts, New Order
10 minPairs
Pairs rebuild the invented bike rack article from the warm-up with a different structure and keep every fact. Then they explain how the new order changes what a reader notices and what idea comes through.
Choose One Rebuild
Chronological: a diary from September to January, one entry per event
Result first: begin with the new 40-bike rack and then explain how it came about
Cause and effect: begin with the new bike lane on Oak Street and follow what it caused
Procedure
Pairs write the new version in four to six short paragraphs, keeping all the numbers: 60 riders, 24 spaces, 4 more by parking head to tail, a 40-bike rack
They trade with another pair, who labels each paragraph's job
They write two sentences: what the new structure makes stand out, and what the original structure did better
Model answer for the teacher: a cause-and-effect version makes the bike lane the main point and turns the article into a story about a city decision; the original problem-and-solution order kept the council's work at the center
Variation
For a harder version, pairs rebuild the article as compare and contrast: the front door before and after January.

RI.7.5 Homework: A Second Student Remembers Agassiz
Directions: Read Passage 6 at the end of the lesson plan (in Closure). Cite it by paragraph number, for example (Passage 6, paragraph 2), and cite Scudder's account by passage and paragraph. Answer in complete sentences, and put every quotation in quotation marks.
Part 1: How Verrill Organizes His Letter (Problems 1-3)
Reread Passage 6, paragraph 1. Which sentence states Verrill's main point about how Agassiz taught, and which sentence repeats it at the end of the paragraph? Quote both. What do you expect the next paragraphs to do after an opening like this?
Paragraph 2 begins "In my own case" and paragraph 3 begins "In the case of Hyatt." What job does each paragraph do for the point in paragraph 1? Quote one detail from each paragraph and explain how it supports the point.
The letter ends, "I mention these cases to show how different his methods were in different cases." What does this sentence do for the whole letter? Why might Verrill have put it at the end instead of at the start of paragraph 3?
Part 2: Two Structures, Two Purposes (Problems 4-6)
Name the structure of Verrill's letter and the structure of Scudder's account, using Diagram 2. For each, explain how the structure fits what the writer wants to show. Use one quotation from each text.
Suppose Verrill had told Hyatt's case first, then his own, and had never stated his point in paragraph 1. How would the development of his idea change for a reader? Would the letter still work? Explain.
Write a paragraph of 6-8 sentences answering: How do the major sections of Scudder's account work together to develop his idea about learning to observe? Discuss at least three sections, with a quotation from each, and explain what each one adds to the whole.

Question 1 of 20 · Multiple Choice
A student's report on volcanoes has three sections: what a volcano is, why volcanoes erupt, and what happens to nearby towns after an eruption. What does the middle section contribute to the whole report?
Answer: B
The middle section explains why eruptions happen, so it connects what a volcano is (section 1) to the damage eruptions cause (section 3): a cause-and-effect link. Choice A describes a chronological section the report does not have. Choices C and D name comparison and opinion, which no section of this report is described as doing.
Question 2 of 20 · Multiple Choice
Which question helps a reader analyze how a section contributes to the development of the ideas, rather than only summarize it?
Answer: D
Development means how an idea grows or changes, so the useful question asks what the section adds to the reader's understanding of the idea. Choice C asks for a summary of events, which is a first step but not analysis. Choices A and B count parts of the text without asking what they do.
Question 3 of 20 · Multiple Choice
A science article begins, "Many people think bats are blind." It then gives three examples of how bats see and hunt, and ends, "Bats are not blind at all." Which structure does it use?
Answer: A
The article states a common belief, gives examples, and ends with a corrected claim, so it is organized as a claim and examples. Nothing in it moves through time (Choice B), describes a problem being fixed (Choice C) or traces causes of a disease (Choice D); choosing one of those means picking a structure from the topic instead of from how the parts are arranged.
Question 4 of 20 · Multiple Choice
In Passage 2, paragraph 1, Scudder finds his fish "dry all over" and dashes "the fluid over the fish as if to resuscitate the beast from a fainting-fit." How does this small event connect to other sections?
Answer: C
In Passage 1, Scudder was told to moisten the fish "occasionally" with alcohol, and in Passage 2, paragraph 3, Agassiz says, "I am glad to notice, too, that you keep your specimen wet." The dried fish links the two moments. Choice A reads "resuscitate" literally; the fish is a preserved specimen. Choice B goes too far, since Scudder keeps working, and Choice D makes up a cause the text never gives.
Question 5 of 20 · Multiple Choice
Passage 2, paragraph 2, says, "My two hands, my two eyes, and the fish: it seemed a most limited field." What does this sentence do in the structure of Section 2?
Answer: B
The sentence comes just before "At last a happy thought struck me," so it sums up how little Scudder thinks he can do before the turning point. Choice A misplaces it: the section goes on and does not end there. Choice C invents a flashback, and Choice D mistakes one comparison inside a sentence for a change in the structure of the whole.
Question 6 of 20 · Multiple Choice
In Passage 3, paragraph 3, Scudder gives a long list of the parts he reported, from "the fringed gill-arches" to "the compressed and arched body." Why does the length of this list matter to the section?
Answer: D
The list shows how much Scudder has found, and Agassiz even waits "as if expecting more." Then comes "You have not looked very carefully." The long list builds up to a surprise. Choice A contradicts the text, which says the parts' "names were still unknown to me." Choice B has no support: Agassiz "listened attentively." Choice C is the opposite of what a detailed list does.
Question 7 of 20 · Short Answer
Reread the last paragraph of Passage 3 ("This was disconcerting ..."). Explain how this paragraph ends Section 3 and what it adds to the idea of learning to look.
Model answer: The paragraph closes the first day: Scudder "walked home by Charles River in a distracted state, with my two perplexities." It adds something new to the idea of looking. Up to now, looking happened with the fish in front of him; now he must keep "studying, without the object before me," and give "an exact account" from memory the next day. Learning to look has become thinking and remembering too, and the unanswered question pulls the reader into the next section. Rubric: 2 points for explaining both the ending of the section and the new step in the idea, with a quotation; 1 point for one of the two; 0 points otherwise.
Question 8 of 20 · Multiple Choice
Which sentence from Passage 3 marks the point where Scudder's attitude toward the task changes from hurt feelings to effort?
Answer: A
Paragraph 5 opens with "I was piqued; I was mortified," and then turns on "But": "But now I set myself to my task with a will," after which he discovers "one new thing after another." Choices B and C come before the criticism, so they cannot show a change after it. Choice D is Agassiz's reaction, not a change in Scudder's own attitude.
Question 9 of 20 · Multiple Choice
Passage 4, paragraph 2, gives Scudder's answer: "that the fish has symmetrical sides with paired organs." What does this answer do for the structure of the account?
Answer: C
At the end of Passage 3, Scudder spends the night wondering what "this unknown but most visible feature might be"; the next morning he names it, and Agassiz answers "'Of course! of course!'" The answer resolves the open question. Choice A misses the link, Choice B contradicts Agassiz's pleased reply, and Choice D confuses a new morning with a flashback.
Question 10 of 20 · Multiple Choice
Agassiz's command appears as "look again, look again!" (Passage 3), "Oh, look at your fish!" (Passage 4, paragraph 4) and "'Look, look, look'" (Passage 4, paragraph 5). How does this repetition help the structure?
Answer: B
The same command returns at each stage, so it links the sections and reminds the reader that looking is the idea the whole account is about. Choice A misreads it as forgetfulness, when the words come "more earnestly" and are called "his repeated injunction." Choice C is inaccurate: the commands come in the middle of days. Choice D ignores the time order that organizes the account.
Question 11 of 20 · Multiple Choice
Passage 4 ends with a paragraph that begins, "This was the best entomological lesson I ever had." Why is this reflection placed right after the three days of looking?
Answer: D
After "for three long days he placed that fish before my eyes," Scudder pauses the story to say what those days meant: a lesson "whose influence has extended to the details of every subsequent study." That is a reflection, placed where the first stage of the lesson is complete. Choice A misses that no event happens in the paragraph. Choice B contradicts the paragraph, which calls the lesson a legacy "of inestimable value." Choice C gives a reason the text never states.
Question 12 of 20 · Short Answer
Passage 4, paragraph 6, calls the fish lesson "the best entomological lesson I ever had." Using a detail from Passage 1, explain why that phrase is surprising and how it connects the end of this section to the beginning of the account.
Model answer:Entomological means about insects, but the lesson was about a fish. In Passage 1, Scudder said he "purposed to devote myself specially to insects" and that "gazing at a fish did not commend itself to an ardent entomologist." Calling the fish lesson his best insect lesson closes a loop with the beginning: the thing he was disappointed to study taught him the skill he used for insects. It shows that the lesson was about observing, not about fish. Rubric: 2 points for a correct link to a quoted Passage 1 detail and an explanation of the surprise; 1 point for one of the two; 0 points otherwise.
Question 13 of 20 · Multiple Choice
In Passage 5, the blackboard story happens "A year afterward" but is told before "The fourth day." What is the effect of placing it there?
Answer: A
Right after saying the lesson's influence lasted, Scudder jumps ahead to prove it: a year later, Agassiz recognizes his fish drawings as "Haemulons, every one of them," and Scudder says "to this day ... I can draw nothing but haemulons." Then he goes back to the fourth day. Choice B misreads a joke among students as a failure. Choice C adds a claim the passage never makes: the students are drawing for fun, and the next paragraph returns to real fish. Choice D treats a deliberate choice as a mistake; the signal words show he knew the order.
Question 14 of 20 · Multiple Choice
Which detail in Passage 5 answers the complaint about the smell in Passage 1?
Answer: C
In Passage 1, the alcohol had "a very ancient and fishlike smell" and left a "perfume which haunted me like a shadow." In Passage 5, paragraph 4, "the odor had become a pleasant perfume." The repeated word shows how far Scudder's attitude has changed. Choice A describes chalk drawings, Choice B describes the number of jars, and Choice D describes later work; none of them mentions the smell.
Question 15 of 20 · Multiple Choice
Passage 5, paragraphs 4 and 5, move from one fish to "the resemblances and differences between the two" and then to "the whole group of haemulons." How does this part develop the idea of the account?
Answer: D
The idea moves up a step: first one fish, then two, then a whole family, so observing becomes comparing. Choice A contradicts the text, since the method continues with more fish. Choice B invents a failure, and Choice C turns a detail about the jars into the main point.
Question 16 of 20 · Multiple Choice
Near the end of the account, Agassiz says, "'Facts are stupid things,' he would say, 'until brought into connection with some general law.'" What does this quotation add to the development of the ideas?
Answer: B
The account has built the idea of careful looking stage by stage. This quotation adds a new stage: observed facts must be linked to a general rule to mean something. Choice A misreads "stupid" as rejecting observation, which Agassiz keeps demanding. Choice C is wrong because Passage 1 was about caring for specimens, not general laws. Choice D has no support: Scudder calls the training of "greater value than years of later investigation."
Question 17 of 20 · Short Answer
Explain how the last paragraph of Passage 5 works as a conclusion to the whole account. Connect it to at least one detail from an earlier section.
Model answer: The last paragraph ends the time order ("At the end of eight months") and brings Scudder back to where he started: he "turned to insects," the subject he came to study in Passage 1. But he has changed. He now calls the fish "these friends," when in Passage 2 the fish was "loathsome" and "hideous," and he leaves them "almost with reluctance." The last sentence states the lesson's value in the largest terms: it was worth more "than years of later investigation." Rubric: 2 points for explaining how the paragraph closes the account and quoting an earlier detail that it answers; 1 point for one of the two; 0 points otherwise.
Question 18 of 20 · Multiple Choice
The account opens, "It was more than fifteen years ago," and its last sentence says the fish lesson was worth more "than years of later investigation." What do this opening and this ending do for the structure of the whole account?
Answer: B
The opening places the reader about fifteen years after the events, and the ending measures the lesson against "years of later investigation." Together they frame the whole account as an older Scudder looking back, which is why he can step out of the story to say what the stages meant. Choice A confuses the time since the events with the length of the lesson, which ended "At the end of eight months." Choice C contradicts the opening, which says the events happened long before the writing. Choice D names a compare-and-contrast structure, but the account follows one teacher and one student.
Question 19 of 20 · Short Answer
Scudder could have ended his account with the reflection at the end of Passage 4. Explain what Passage 5 adds that the account would lose without it. Use at least two quotations from Passage 5.
Model answer: Without Passage 5, the account would end with one fish and a general statement of the lesson's value. Passage 5 adds proof of how long the lesson lasted: "to this day, if I attempt a fish, I can draw nothing but haemulons." It also takes the idea further, from looking at one fish to comparing "the resemblances and differences" and to Agassiz's warning that "Facts are stupid things ... until brought into connection with some general law." Finally, it completes Scudder's change of attitude, since the fish become "these friends." Rubric: 2 points for naming at least two things Passage 5 adds, each supported by a quotation; 1 point for one supported point; 0 points otherwise.
Question 20 of 20 · Short Answer
Why is chronological order a good structure for the idea Scudder wants to develop? Explain, using evidence from at least two sections.
Model answer: Scudder's idea is that careful observing has to be learned slowly, and a time-order structure lets the reader live through that slow learning. The signals mark each stage: the first ten minutes, the next morning, "for three long days" (Passage 4), then "The fourth day" and "At the end of eight months" (Passage 5). Each stage changes what he does, from staring at one fish to comparing "the entire family" (Passage 5). A list of Agassiz's rules would state the idea, but only the time order shows it growing. Rubric: 2 points for linking the structure to the idea with evidence from two sections; 1 point for evidence from one section or a link without evidence; 0 points otherwise.

Frequently Asked Questions
10 Questions
What does RI.7.5 mean?
It means seventh graders analyze how an informational text is organized. They name the structure, divide the text into its major sections, and explain how each section contributes to the whole text and to the development of its ideas. Naming the structure alone is not enough.
How is RI.7.5 different from RI.6.5 and RI.8.5?
RI.7.5 looks at the whole text and its major sections. RI.6.5 asks how one sentence, paragraph, chapter or section fits into the overall structure. RI.8.5 zooms in: students analyze the structure of one specific paragraph and the role of particular sentences in developing a key concept.
What are the common text structures students should know?
Five cover most informational texts: chronological (time order), compare and contrast, cause and effect, problem and solution, and claim and examples, sometimes called description. Diagram 2 lists signal words for each. Real texts often combine two structures, as the bike rack article combines problem and solution with a cause section.
How do students find the major sections of a text without headings?
They look for a change in time, place, topic or purpose, often marked by a signal word such as "the next morning" or "A year afterward." A section may be one paragraph or many. Students should defend each break with evidence, and different breaks can be right if they are well argued.
Can a true story be used to teach RI.7.5?
Yes. Personal accounts, memoirs and news stories are informational texts, and many are organized in time order. They are useful for RI.7.5 because students can see that even chronological writing has sections with jobs, and that authors sometimes break time order on purpose, as Scudder does with his blackboard story.
How do I get students past just naming the structure?
Use the removal test. Ask, "What would the reader lose if this section were cut?" and "How has the idea changed by the end of this section?" Students who can answer both, with a quotation, are analyzing the structure rather than labeling it. The sentence frame in Direct Instruction builds in both questions.
Who were Louis Agassiz and Samuel Scudder?
Agassiz (1807-1873) was a Swiss-born naturalist who taught at Harvard and founded its Museum of Comparative Zoology. Scudder (1837-1911) studied with him and became a leading American expert on insects. Scudder's 1874 account of his first days in Agassiz's laboratory is often retold as "Look at Your Fish."
How is RI.7.5 usually assessed?
Usually with questions about what a paragraph or section does in a passage, how it connects to another part, or why the author put it where it is. Wrong options often summarize the section instead of naming its job. Written responses ask students to explain how sections build an idea, with evidence, as this lesson's quiz and homework do.
How does RI.7.5 connect to student writing?
Directly. The grade 7 informative writing standard, W.7.2, asks students to organize ideas using strategies such as comparison and contrast and cause and effect, and to use transitions. Students who can see why an author placed a section can plan their own sections, and Activity 3 has them rebuild a short article in a new structure.
Is the Scudder account too hard for seventh graders?
Not with support. Some words are old-fashioned and scientific, so each passage comes with a word list, but the story itself is simple and often funny: a young man stuck with a smelly fish and a teacher who keeps saying "look again." The account is short, which makes it easy to see the whole structure at once.
