RI.8.2: A Central Idea, Its Supporting Ideas and an Objective Summary

In plain English: RI.8.2 is the Common Core grade 8 ELA standard that asks students to determine a central idea of an informational text and analyze how it develops over the whole text, including how each supporting idea relates to it. Students also write an objective summary without opinions. It builds on RI.7.2.

Determine a central idea of a text and analyze its development over the course of the text, including its relationship to supporting ideas; provide an objective summary of the text.

Lesson Plan

55-65 min

Overview

Students learn to find a central idea that runs through a whole informational text, to trace how it develops from the first page to the last, and to explain how each supporting idea is related to it: whether it explains why, proves with an example, shows how, shows a result or shows how much the idea matters. They also write an objective summary: the central idea and the main supporting ideas in order, in their own words, with no opinions and no judgments.

The text is Mary Antin's autobiography The Promised Land (1912). Antin was a Jewish girl from the Russian Empire who came to Boston with her mother, two sisters and a brother in 1894, when she was about thirteen, and started school in Chelsea, Massachusetts, that fall. One central idea runs through the four passages: free public schools, and the teachers who taught her there, opened a new life for Mary Antin in America. The teacher models the idea and two of its supporting ideas in Passage 1, the family's first days in Boston. Pairs trace the idea through Passage 2, students analyze Passage 3 on their own, and the homework uses Passage 4, where Antin sees her own writing in print for the first time.

Learning Objectives

By the end of this lesson, students will be able to:

  • State a central idea of an informational text as a complete sentence and tell it apart from a topic or a detail
  • Trace how the central idea develops over the course of a text, from where it is introduced to where it is fulfilled
  • Explain the relationship between the central idea and each supporting idea: explains why, proves with an example, shows how, shows a result, or shows how much it matters
  • Write an objective summary that gives the central idea and main supporting ideas in order, with no opinions or judgments

Prior Knowledge Required

Students should already be comfortable with:

  • Finding two or more central ideas in an informational text and writing an objective summary RI.7.2
  • Finding a theme or central idea in a story RL.7.2
  • Citing textual evidence with passage and paragraph numbers RI.7.1
  • Telling a fact from an opinion

Lesson Procedure

55-65 minutes of class time across 5 phases.

  1. Warm-Up5-10 minutes

    Warm-Up Prompt

    "At the end-of-season dinner, a soccer coach talks about the season: the team lost its first three games, the players asked for extra practices on Saturdays, a player who was hurt came to every game to cheer, and the team won the final. In one sentence, what is the main point of her speech? Then pick one part of the speech and say what job it does for that point."

    Collect the main points and push for a full sentence ("the team got better by working together" rather than "teamwork"). Then take the jobs: the three losses show where the team started, the Saturday practices show how it improved, the injured player shows how much the team mattered to its members, and the final win shows the result. Tell students that grade 8 asks them to find a text's central idea, show how the text builds it, and explain the job each supporting idea does.

  2. Direct Instruction15 minutes

    Teach five terms, and leave them on the board:

    • Central idea: the most important point a text makes about its topic, written as a complete sentence. "School" is a topic; "free school changed her life" is an idea.
    • Supporting idea: a smaller point that helps the central idea, usually a paragraph or a section of the text. It is bigger than a single detail (a fact, a name, an event).
    • Relationship: the job a supporting idea does for the central idea. Five common jobs: it explains why, it proves with an example, it shows how, it shows a result, or it shows how much it matters.
    • Development: how the central idea changes or grows over the text. In these passages it is introduced as a promise, proven by an event, deepened as students see how it works, and fulfilled by the end.
    • Objective summary: a short retelling of the central idea and main supporting ideas, in order and in your own words, without your opinions, judgments or outside information.

    Introduce the text. Mary Antin (1881-1949) grew up in Polotzk, a town in the Russian Empire (today Polotsk, in Belarus), where Jewish families lived under harsh laws that limited where they could live, work and study. Her father went to Boston first, and three years later he sent for the family. The Promised Land is her account of that journey and of her first years in America, written when she was about thirty. Passage 1 begins on the family's first evening in Boston, in May 1894. Words to know: conducted (led), public baths (city bathhouses for people whose homes had no bathtub), illumination (lighting), synagogue (a Jewish house of worship), serenaded (sung or played to), installation (here, moving in), essence (the most important part), machinations (secret schemes), concrete (real and definite) and Crescent Beach (a beach near Boston where her father ran a refreshment stand that summer). Read the passage aloud.

    [...] So in the evening of the first day my father conducted us to the public baths. As we moved along in a little procession, I was delighted with the illumination of the streets. So many lamps, and they burned until morning, my father said, and so people did not need to carry lanterns. In America, then, everything was free, as we had heard in Russia. Light was free; the streets were as bright as a synagogue on a holy day. Music was free; we had been serenaded, to our gaping delight, by a brass band of many pieces, soon after our installation on Union Place.

    Education was free. That subject my father had written about repeatedly, as comprising his chief hope for us children, the essence of American opportunity, the treasure that no thief could touch, not even misfortune or poverty. It was the one thing that he was able to promise us when he sent for us; surer, safer than bread or shelter. On our second day I was thrilled with the realization of what this freedom of education meant. A little girl from across the alley came and offered to conduct us to school. My father was out, but we five between us had a few words of English by this time. We knew the word school. We understood. This child, who had never seen us till yesterday, who could not pronounce our names, who was not much better dressed than we, was able to offer us the freedom of the schools of Boston! No application made, no questions asked, no examinations, rulings, exclusions; no machinations, no fees. The doors stood open for every one of us. The smallest child could show us the way.

    This incident impressed me more than anything I had heard in advance of the freedom of education in America. It was a concrete proof--almost the thing itself. One had to experience it to understand it.

    It was a great disappointment to be told by my father that we were not to enter upon our school career at once. It was too near the end of the term, he said, and we were going to move to Crescent Beach in a week or so. We had to wait until the opening of the schools in September. What a loss of precious time--from May till September!

    • Topic, detail or central idea?

      Three students answer "What is Passage 1 mostly about?" One writes "school." One writes "A girl offered to take them to school." One writes "For Antin, free school was the greatest freedom America offered." Which is a central idea?

      Result: Only the third. "School" is a topic: it names the subject but makes no point. The second is a detail: one event from paragraph 2. The third is a complete sentence that makes a point the whole passage supports. The key sentence is "Education was free" (paragraph 2), which Antin sets apart as a new paragraph after listing other free things.

    • A supporting idea that explains why

      Paragraph 2 says education was her father's "chief hope for us children" and "surer, safer than bread or shelter." What is the relationship between this supporting idea and the central idea?

      Result: It explains why free school mattered so much. For a family that had lost almost everything, food and a home could be taken away, but learning could not; that is why he calls it "the treasure that no thief could touch, not even misfortune or poverty" (paragraph 2).

    • A supporting idea that proves with an example

      The girl from across the alley appears in paragraph 2. What job does she do for the central idea?

      Result: She proves it with an example. Antin says so herself: "This incident impressed me more than anything I had heard in advance of the freedom of education in America. It was a concrete proof" (paragraph 3). Until that morning, free school was only something her father had written about; now she has seen it.

    • Objective or not? A summary of Passage 1

      Compare two summaries. Summary A: "Antin's family was lucky to live in amazing Boston, where the streets were beautiful. A sweet neighbor girl showed them the school, which was the best part." Summary B is below.

      Result: Summary B is objective: "On the family's first evening in Boston, Antin's father led them through streets that stayed lit all night, and Antin decided that in America things like light and music were free. Education mattered most: her father had long called it his main hope for his children. The next day a girl from across the alley offered to take them to school, and Antin saw this as proof that school was open to everyone. The children had to wait several months to begin, and Antin was disappointed." Summary A uses judgments (lucky, amazing, sweet, the best part), leaves out the father's hope and the wait, and never states the central idea.

    Name it, map it, trace it. Show Diagram 1. Model the three moves: name the central idea in one sentence; map each supporting idea to it with an arrow labeled by its job; trace the idea from passage to passage on the development line (Diagram 2), which the class keeps all lesson. Leave the two open spokes on Diagram 1 for Activity 1. Sentence frames: "The central idea is that ___." "Paragraph __ supports it by showing ___; its job is to ___." "In Passage __, the idea grows when ___."

  3. Guided Practice15 minutes

    Before reading, retell what comes between the passages: the family spent the summer at Crescent Beach, then moved to Chelsea, next to Boston, and in September 1894 Antin started school. Although she was about thirteen, she sat in the first-grade class to learn English, and within a week her teacher, Miss Nixon, moved her up to the second grade. Read Passage 2 aloud. Words to know: endeavors (tries), ravishing (thrilling), our own tongue (their home language, Yiddish), native classes (classes of children born in America), tots (small children), the definite article (the word "the"), lingual gymnastics (tongue exercises), perseverance (not giving up), becoming to her (a credit to her), declaration (announcement), inherit (receive from people who came before) and conviction of immortality (her belief in life after death).

    There were about half a dozen of us beginners in English, in age from six to fifteen. Miss Nixon made a special class of us, and aided us so skilfully and earnestly in our endeavors to "see-a-cat," and "hear-a-dog-bark," and "look-at-the-hen," that we turned over page after page of the ravishing history, eager to find out how the common world looked, smelled, and tasted in the strange speech. The teacher knew just when to let us help each other out with a word in our own tongue,--it happened that we were all Jews,--and so, working all together, we actually covered more ground in a lesson than the native classes, composed entirely of the little tots.

    But we stuck--stuck fast--at the definite article; and sometimes the lesson resolved itself into a species of lingual gymnastics, in which we all looked as if we meant to bite our tongues off. Miss Nixon was pretty, and she must have looked well with her white teeth showing in the act; but at the time I was too solemnly occupied to admire her looks. I did take great pleasure in her smile of approval, whenever I pronounced well; and her patience and perseverance in struggling with us over that thick little word are becoming to her even now, after fifteen years. It is not her fault if any of us to-day give a buzzing sound to the dreadful English th.

    I shall never have a better opportunity to make public declaration of my love for the English language. I am glad that American history runs, chapter for chapter, the way it does; for thus America came to be the country I love so dearly. I am glad, most of all, that the Americans began by being Englishmen, for thus did I come to inherit this beautiful language in which I think. It seems to me that in any other language happiness is not so sweet, logic is not so clear. I am not sure that I could believe in my neighbors as I do if I thought about them in un-English words. I could almost say that my conviction of immortality is bound up with the English of its promise. And as I am attached to my prejudices, I must love the English language!

    Mary Antin, The Promised Land, chapter X, "Initiation" (Passage 2: Miss Nixon's class) (1912). Public domain (published 1912). Source text.

    Pairs work on paragraph 1 of Passage 2 with the development line (Diagram 2) open. Ask for the exact words first, then share the teacher notes:

    1. Name the supporting idea. In one sentence, what point does paragraph 1 make? Teacher note: a skilled teacher found a way to help beginners of every age learn fast. The key words are "Miss Nixon made a special class of us" and "working all together, we actually covered more ground in a lesson than the native classes."
    2. Name its job. Which relationship does paragraph 1 have to the central idea? Teacher note: it shows how free school worked for Antin: through a teacher's method, including knowing "just when to let us help each other out with a word in our own tongue." Accept "proves with an example" if students explain it.
    3. Key detail or minor detail? Pairs sort three details: the reading-book sentences "see-a-cat" and "hear-a-dog-bark"; the ages "from six to fifteen"; and "we actually covered more ground in a lesson than the native classes." Teacher note: the last is key, because it shows the method worked; the ages are useful context; the reading-book sentences are colorful but minor, and a short summary can leave them out.
    4. Add it to the line. Pairs write paragraph 1's supporting idea in the Passage 2 box of Diagram 2. They finish the Passage 2 box, with paragraphs 2 and 3, as part of the quiz.
  4. Independent Practice15 minutes

    Students read Passage 3 on their own. It follows Passage 2 directly, and three paragraphs are left out where the [...] appears; in them, Antin moves up again and meets Miss Dillingham, her teacher in the next grade. Antin tells the scene with Miss Carrol in the present tense, as if it were happening now, and spells out her accent. Words to know: private difficulties (problems only she had), needs must (had to), beckons (signals someone to come), efficiency (getting a job done without waste), alternation (taking turns, one after the other), initials (first letters), posy (a small bunch of flowers), chamber (room), nasturtiums, pansies, honeysuckle (garden flowers), carnival (here, a bright crowd), tumbler (a drinking glass) and initiation (a beginning in a new group or way of life).

    Whenever the teachers did anything special to help me over my private difficulties, my gratitude went out to them, silently. It meant so much to me that they halted the lesson to give me a lift, that I needs must love them for it. Dear Miss Carrol, of the second grade, would be amazed to hear what small things I remember, all because I was so impressed at the time with her readiness and sweetness in taking notice of my difficulties.

    Says Miss Carrol, looking straight at me:--

    "If Johnnie has three marbles, and Charlie has twice as many, how many marbles has Charlie?"

    I raise my hand for permission to speak.

    "Teacher, I don't know vhat is tvice."

    Teacher beckons me to her, and whispers to me the meaning of the strange word, and I am able to write the sum correctly. It's all in the day's work with her; with me, it is a special act of kindness and efficiency.

    [...]

    I remember to this day what a struggle we had over the word "water," Miss Dillingham and I. It seemed as if I could not give the sound of w; I said "vater" every time. Patiently my teacher worked with me, inventing mouth exercises for me, to get my stubborn lips to produce that w; and when at last I could say "village" and "water" in rapid alternation, without misplacing the two initials, that memorable word was sweet on my lips. For we had conquered, and Teacher was pleased.

    Getting a language in this way, word by word, has a charm that may be set against the disadvantages. It is like gathering a posy blossom by blossom. Bring the bouquet into your chamber, and these nasturtiums stand for the whole flaming carnival of them tumbling over the fence out there; these yellow pansies recall the velvet crescent of color glowing under the bay window; this spray of honeysuckle smells like the wind-tossed masses of it on the porch, ripe and bee-laden; the whole garden in a glass tumbler. So it is with one who gathers words, loving them. Particular words remain associated with important occasions in the learner's mind. I could thus write a history of my English vocabulary that should be at the same time an account of my comings and goings, my mistakes and my triumphs, during the years of my initiation.

    Mary Antin, The Promised Land, chapter X, "Initiation" (Passage 3: help, one word at a time; three paragraphs cut, marked [...]) (1912). Public domain (published 1912). Source text.

    On the handout, students (1) state, in one sentence, the supporting idea that Passage 3 adds; (2) explain how paragraphs 1-6 change the idea of teachers' help from Passage 2, citing one detail from each passage; (3) name the job of paragraph 8 and explain it in two sentences; (4) write an objective summary of Passage 3 in three or four sentences and check it for opinion words. The quiz uses Passages 2 and 3, and Question 16 also reaches back to Passage 1.

  5. Closure5-10 minutes

    Exit ticket: (1) Write the central idea of Passages 1-3 in one sentence without looking at the board. (2) Choose one supporting idea from any passage, name its job (explains why, proves with an example, shows how, shows a result, shows how much it matters) and give one quotation.

    Teacher note on history and language: The Promised Land was published in 1912, about eighteen years after these events, so it is Antin's memory of them. She writes as someone deeply grateful to her new country, and her book was very popular in its time. Some readers today point out what the process cost her family: in the same chapter where Antin finds free school, the family's friends replace their Hebrew names with American ones. Antin tells this herself, in wry words: her mother "was punished with the undignified nickname of Annie." Antin also went on to speak out against new limits on immigration, in They Who Knock at Our Gates (1914). Invite students to notice that a writer's central idea is her view, and that other immigrants have told the story differently; this is a good discussion, and it is separate from an objective summary, which reports Antin's view without judging it. Antin spells out her own accent ("vhat is tvice," "vater") to show how hard some English sounds were for her and how patiently her teachers helped; she presents the struggle with pride in overcoming it, not as something to laugh at. Read those lines as she wrote them, do not have students imitate the accent for fun, and remember that some students in the class may be learning English themselves. The passages print dashes as double hyphens, as the 1912 edition does.

    For homework: students read Passage 4, printed below. Before it begins, Antin copies into her book the composition "Snow" that she wrote four months after starting to learn English. Miss Dillingham had sent it to a magazine for teachers, which printed it with Antin's name. Words to know: flippant (joking, not serious), vanity (too much pride in yourself), conquest (winning or mastering), association (connection), composition (a piece of school writing), consciousness (awareness of yourself and the world), accommodate (make room for) and coaxed (gently urged).

    And now that it stands there, with her name over it, I am ashamed of my flippant talk about vanity. More to me than all the praise I could hope to win by the conquest of fifty languages is the association of this dear friend with my earliest efforts at writing; and it pleases me to remember that to her I owe my very first appearance in print. Vanity is the least part of it, when I remember how she called me to her desk, one day after school was out, and showed me my composition--my own words, that I had written out of my own head--printed out, clear black and white, with my name at the end! Nothing so wonderful had ever happened to me before. My whole consciousness was suddenly transformed. I suppose that was the moment when I became a writer. I always loved to write,--I wrote letters whenever I had an excuse,--yet it had never occurred to me to sit down and write my thoughts for no person in particular, merely to put the word on paper. But now, as I read my own words, in a delicious confusion, the idea was born. I stared at my name: MARY ANTIN. Was that really I? The printed characters composing it seemed strange to me all of a sudden. If that was my name, and those were the words out of my own head, what relation did it all have to me, who was alone there with Miss Dillingham, and the printed page between us? Why, it meant that I could write again, and see my writing printed for people to read! I could write many, many, many things: I could write a book! The idea was so huge, so bewildering, that my mind scarcely could accommodate it.

    [...]

    I ought to go back and strike out all that talk about vanity. What reason have I to be vain, when I reflect how at every step I was petted, nursed, and encouraged? I did not even discover my own talent. It was discovered first by my father in Russia, and next by my friend in America. What did I ever do but write when they told me to write? [...]

    I never heard of any one who was so watched and coaxed, so passed along from hand to helping hand, as was I. I always had friends. They sprang up everywhere, as if they had stood waiting for me to come. [...]

Differentiation Strategies

For Struggling Students

  • Give the five relationship jobs on a card with a question for each (Why? For example? How? What happened? How much?) and have students ask all five of a paragraph
  • Provide the central idea sentence and ask students only to map and trace it
  • Let students write the summary as four numbered sentences, one per paragraph of Passage 1, before joining them

For Advanced Students

  • Ask them to find the one paragraph in Passages 1-3 that fits the central idea least well and argue whether it still belongs
  • Have them rewrite the central idea so that it also covers Passage 4, then explain what the new wording adds
  • Ask them to write a second summary of Passage 1 from the point of view of a reader who disagrees with Antin, and then explain why that version is no longer objective

Assessment Guidance

What to Look For

Check that the central idea is a complete sentence about the whole text, not a topic word or one event. When students explain a supporting idea, look for a named job (explains why, proves with an example, shows how, shows a result, shows how much it matters) and a quotation. When they trace development, look for change: where the idea is a promise, where it is proven, and where it becomes personal. In summaries, watch for opinion words (amazing, lucky, sadly), loaded verbs (brags, whines), outside information, and minor details that crowd out the supporting ideas.

Classroom Activities

3 Activities

1

What Job Does It Do?

15 minPairs

Pairs match six supporting-detail cards from Passages 1 and 2 to five job cards, then place each match on a copy of Diagram 1 around the central idea. One job is used twice. The goal is to see that every supporting idea is there for a reason.

The Six Detail Cards and Five Job Cards

  • Card 1: "Light was free; the streets were as bright as a synagogue on a holy day. Music was free" (Passage 1, paragraph 1)
  • Card 2: "This child, who had never seen us till yesterday, who could not pronounce our names" (Passage 1, paragraph 2)
  • Card 3: "What a loss of precious time--from May till September!" (Passage 1, paragraph 4)
  • Card 4: "the treasure that no thief could touch" (Passage 1, paragraph 2)
  • Card 5: "Miss Nixon made a special class of us" (Passage 2, paragraph 1)
  • Card 6: "The doors stood open for every one of us" (Passage 1, paragraph 2)

Job cards: explains why; proves with an example; shows how; shows how much it matters; sets up a pattern (a list of smaller cases that leads up to the main one).

Procedure

  • Pairs read each card aloud, pick a job, and write one "because" sentence under it
  • They place the cards on Diagram 1, filling the two open spokes first
  • Answer key for the teacher: Card 1 sets up a pattern (smaller free things lead up to "Education was free"). Cards 2 and 6 prove with an example (a stranger, no older than Antin, can lead them in; nobody is turned away). Card 3 shows how much it matters (a summer's wait feels like a loss). Card 4 explains why (learning cannot be stolen). Card 5 shows how (a teacher's special class)

Discussion Questions

  • Cards 2 and 6 do the same job. Which one is stronger proof, and why?
  • Could Card 3 also be read as "shows a result"? What would you have to argue?
  • If Antin had cut paragraph 1 of Passage 1, what would the central idea lose?

Modification

For students who need support, give three cards (1, 4 and 5) and three job cards only, then add the rest.

2

Summary Makeover

15 minGroups of 3-4

Groups get three flawed summaries of Passage 1, written for this activity, each with a different problem. They diagnose each one, then write a single objective summary that fixes all three problems.

The Three Flawed Summaries

  1. The Retelling: "Antin's father took them to the public baths. The streets had many lamps that burned until morning. A brass band played. Her father had written letters. A girl came from across the alley. The family knew the word school. They were going to Crescent Beach. School started in September."
  2. The Review: "This is a heartwarming story about a family that finally got lucky. Antin's father was a wonderful man, and the little girl was the real hero. Honestly, waiting until September was silly, and they should have started right away."
  3. The Wrong Center: "Passage 1 is mostly about the bright lamps and music in Boston. Antin loved the lights because in Polotzk the streets were dark, and she enjoyed the brass band. She also mentions school."

Procedure

  • For each summary, groups name the problem in two or three words and underline the words that cause it
  • Then they write one objective summary of four or five sentences and check it against the central idea
  • Answer key for the teacher: (1) a retelling: every detail gets equal weight, some are minor, and it never states the central idea. (2) a review: opinion and judgment words (heartwarming, lucky, wonderful, real hero, silly) and advice to the family. (3) the wrong center: a supporting idea is treated as the main point, and it adds outside information the passage never gives (dark streets in Polotzk). A fixed version names the central idea, keeps the free lamps and music as the lead-in, gives the father's hope, the girl's offer as proof, and the wait, all without opinions

Discussion Questions

  • Summary 1 is accurate. Why is it still a weak summary?
  • Summary 3 includes a claim about Polotzk. How can you tell it did not come from the passage?
  • Which problem was hardest to fix without losing a key supporting idea?
3

Neutral Words Only

10 minPairs

Pairs rewrite eight summary sentences about Passages 1 and 2 that contain loaded words, words that sneak in a judgment. Each rewrite must keep every fact and remove the judgment.

The Eight Sentences

  1. Antin brags that the streets were as bright as a synagogue.
  2. Her father foolishly promised the children an education.
  3. A pushy girl from across the alley offered to take them to school.
  4. Antin whines about waiting until September.
  5. Miss Nixon cleverly let the students help each other in their own language.
  6. Sadly, Antin had to start out in the first-grade class.
  7. Antin gushes about her love of English.
  8. The class amazingly covered more ground than the native classes.

Procedure

  • Pairs circle the loaded word in each sentence, then rewrite it with a neutral verb (says, states, explains, describes, writes) or no adjective at all
  • Answer key for the teacher: the loaded words are brags, foolishly, pushy, whines, cleverly, sadly, gushes and amazingly. Sample rewrites: (1) Antin writes that the streets were as bright as a synagogue on a holy day. (4) Antin says the wait until September felt like a loss of time. (7) Antin declares her love of the English language. (8) The class covered more ground in a lesson than the native classes

Variation

For a harder version, pairs write four loaded sentences of their own about Passage 2 and trade with another pair, who must neutralize them.

Frequently Asked Questions

10 Questions

What does RI.8.2 mean?

It means eighth graders must find a central idea in a nonfiction text, show how the text develops it from beginning to end, and explain how the smaller supporting ideas connect to it. They also write an objective summary: the central idea and main supporting ideas in their own words, without opinions.

How is RI.8.2 different from RI.7.2?

RI.7.2 asks students to find "two or more central ideas" and trace them. RI.8.2 asks for "a central idea" and adds a new demand: analyzing "its relationship to supporting ideas." In grade 8 students go deeper into one idea and explain the job each supporting idea does for it. In high school, RI.9-10.2 asks how the idea "is shaped and refined by specific details."

What is the difference between a central idea, a supporting idea and a detail?

A central idea is the main point of the whole text, in a sentence. A supporting idea is a smaller point, often a paragraph's worth, that helps the central idea. A detail is a single fact, name, number or event that backs up a supporting idea. In Passage 1 of this lesson, "free school opened a new life for Antin" is the central idea, "a child proves the schools are open" is a supporting idea, and "a little girl from across the alley" is a detail.

What does "relationship to supporting ideas" mean in RI.8.2?

It means the connection, or the job, each supporting idea does. A supporting idea can explain why the central idea is true, prove it with an example, show how it happens, show a result, or show how much it matters. Students should name the job and back it with a quotation, not just list the supporting ideas.

What makes a summary objective?

An objective summary reports what the text says without judging it. It leaves out opinion words (amazing, sadly), loaded verbs (brags, whines), the reader's reactions and outside information. It keeps the central idea and the main supporting ideas in order, in the student's own words.

How long should an objective summary be for RI.8.2?

Usually three to five sentences for a passage of a page or less, and six to eight for a longer text. A good test: every sentence should carry the central idea or a main supporting idea. If a sentence holds only a minor detail, it can usually go.

What is the difference between RI.8.2 and RL.8.2?

RL.8.2 is for stories, poems and plays, and asks for "a theme or central idea" and its relationship to the characters, setting and plot. RI.8.2 is for informational texts and asks how the central idea relates to supporting ideas. In an autobiography like Antin's, which tells true events, the central idea is the writer's point about her own life.

Does the author always state the central idea directly?

No. Sometimes one sentence comes close to stating it, but often the reader has to build the central idea from the supporting ideas. Either way, students should put it in their own words and check that every part of the text fits it.

Why use Mary Antin's The Promised Land to teach RI.8.2?

It is a public-domain autobiography about a subject eighth graders know well, starting school, told by a girl close to their age. Across two chapters, one central idea develops clearly, and each passage adds a new kind of supporting idea, which makes relationships easy to see and discuss.

How can parents help a child practice RI.8.2 at home?

After your child reads a news story or watches a short documentary, ask three questions: "What was the main point, in one sentence?" "Which part helped that point most, and how?" "Can you tell me about it in three sentences without saying whether you liked it?" The last question is practice in objective summary.
