RI.8.1: Citing the Strongest Evidence in Nonfiction

In plain English: RI.8.1 is the Common Core grade 8 ELA standard that asks students to cite the textual evidence that most strongly supports their analysis of a nonfiction text. From several accurate quotations, students choose the one that best proves what the text states or implies and explain why it beats the others. It builds on RI.7.1.

Cite the textual evidence that most strongly supports an analysis of what the text says explicitly as well as inferences drawn from the text.

Lesson Plan

55-65 min

Overview

Students learn what grade 8 adds to citing evidence: choosing the evidence that most strongly supports an analysis. Several quotations may all be accurate and on the topic, but one usually proves the point better than the others. Students test each candidate with three questions (Is it on target? Is it specific? Is it decisive?) and explain why the winner beats the runner-up. They do this for both kinds of claims the standard names: what the text says explicitly and what a reader infers.

The text is John Muir's My First Summer in the Sierra, the journal he kept in 1869 while traveling with a flock of sheep through the Sierra Nevada of California. The teacher models the strength test with Passage 1, Muir's comic portrait of the shepherd Billy (July 20). Pairs rank evidence for Passage 2, where Muir's dog Carlo leads him to a bear, and students work alone on Passage 3, the face-to-face standoff that follows. The homework uses Passage 4, Muir's account of a grasshopper he watched later the same day. All four passages come from chapter V and are printed in the lesson plan.

Learning Objectives

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

  • Choose, from several accurate quotations, the one that most strongly supports a claim about what an informational text states explicitly, and cite it with its passage and paragraph number
  • Choose the strongest evidence for an inference and explain why it settles the question better than the runner-up
  • Test candidate evidence with three questions: is it on target, is it specific, is it decisive?
  • Recognize evidence that is on the right topic but does not prove the claim, and replace it with stronger evidence

Prior Knowledge Required

Students should already be comfortable with:

  • Citing several pieces of textual evidence for what an informational text says explicitly and for inferences drawn from it RI.7.1
  • Citing several pieces of evidence the same way in stories and poems RL.7.1
  • Telling a stated detail from an inference
  • Putting copied words in quotation marks and adding a passage and paragraph number

Lesson Procedure

55-65 minutes of class time across 5 phases.

  1. Warm-Up5-10 minutes

    Warm-Up Prompt

    "The last slice of pizza is gone, and you think your little brother ate it. You have three clues: he loves pizza, he was home alone all afternoon, and there is tomato sauce on his sleeve. All three point to him. Which one is the strongest clue, and why is it stronger than the other two?"

    Collect answers. Many students pick the sauce, and the reasons are what matter: loving pizza is true of many people (not decisive), being home shows he had the chance but not that he took it, and the sauce is a specific trace of the pizza itself. Point out that every clue was relevant, but one did far more work. Tell students that grade 8 asks for exactly this: not just evidence, but the evidence that most strongly supports the point, and a reason for the choice.

  2. Direct Instruction15 minutes

    Review three words and teach three new ones, and leave them on the board:

    • Textual evidence: exact words from the text that back up a claim about it, cited with the passage and paragraph number, for example (Passage 1, paragraph 2).
    • Explicit: stated directly in the words of the text.
    • Inference: a conclusion the text supports but does not state, reached by joining clues in the text with what you already know.
    • Strongest evidence (new): the quotation that proves the claim better than any other one in the text. Grade 7 asked for several pieces; grade 8 asks students to choose among them and defend the choice.
    • The strength test (new): three questions for each candidate. On target: is it about this exact claim, not just the same topic? Specific: does it give a concrete action, detail or statement rather than a general impression? Decisive: does it settle the question, leaving little room for another reading?
    • Runner-up (new): the second-best quotation. Saying why the winner beats the runner-up is how students show that they chose, not just found, their evidence.

    Introduce the text. John Muir (1838-1914) was born in Scotland, grew up in Wisconsin and became a well-known American naturalist and writer about wild places. In the summer of 1869 a sheep owner, Mr. Delaney (called "the Don" in the journal), hired him to go with his shepherd, Billy, and a flock of about two thousand sheep into the high mountains near Yosemite. Muir's job was mainly to see that the shepherd did his work; in his free hours he studied plants, animals and rocks. A hunter lent him a St. Bernard dog named Carlo. Muir kept a journal and published it in 1911 as My First Summer in the Sierra. Words to know for Passage 1: queer (strange; an older meaning of the word), punky dust (crumbly powder from rotten wood), corral (a fenced pen for animals), ammoniacal snuff (Muir's joke: Billy breathes the sharp ammonia smell of the sheep pen all night, the way some people sniffed powdered tobacco, called snuff), six-shooter (a revolver), stalactites (icicle-shaped deposits that hang in caves), oleaginous (oily), apparel (clothing), adhesive (sticky), resin (sticky tree sap), mica, quartz, hornblende (minerals found in rock), naturalist (a person who studies plants, animals and rocks), specimens (samples collected for study), bituminous (tar-like), microcosm (a small world that contains a sample of everything), concentric (in rings around one center), stratification (arrangement in layers, like layers of rock) and rove and revel (wander and enjoy). Read the passage aloud. It is a joke from start to finish, and students should enjoy it.

    Our shepherd is a queer character and hard to place in this wilderness. His bed is a hollow made in red dry-rot punky dust beside a log which forms a portion of the south wall of the corral. Here he lies with his wonderful everlasting clothing on, wrapped in a red blanket, breathing not only the dust of the decayed wood but also that of the corral, as if determined to take ammoniacal snuff all night after chewing tobacco all day. Following the sheep he carries a heavy six-shooter swung from his belt on one side and his luncheon on the other. The ancient cloth in which the meat, fresh from the frying-pan, is tied serves as a filter through which the clear fat and gravy juices drip down on his right hip and leg in clustering stalactites. This oleaginous formation is soon broken up, however, and diffused and rubbed evenly into his scanty apparel, by sitting down, rolling over, crossing his legs while resting on logs, etc., making shirt and trousers water-tight and shiny. His trousers, in particular, have become so adhesive with the mixed fat and resin that pine needles, thin flakes and fibres of bark, hair, mica scales and minute grains of quartz, hornblende, etc., feathers, seed wings, moth and butterfly wings, legs and antennæ of innumerable insects, or even whole insects such as the small beetles, moths and mosquitoes, with flower petals, pollen dust and indeed bits of all plants, animals, and minerals of the region adhere to them and are safely imbedded, so that though far from being a naturalist he collects fragmentary specimens of everything and becomes richer than he knows. His specimens are kept passably fresh, too, by the purity of the air and the resiny bituminous beds into which they are pressed. Man is a microcosm, at least our shepherd is, or rather his trousers. These precious overalls are never taken off, and nobody knows how old they are, though one may guess by their thickness and concentric structure. Instead of wearing thin they wear thick, and in their stratification have no small geological significance.

    Besides herding the sheep, Billy is the butcher, while I have agreed to wash the few iron and tin utensils and make the bread. Then, these small duties done, by the time the sun is fairly above the mountain-tops I am beyond the flock, free to rove and revel in the wilderness all the big immortal days.

    John Muir, My First Summer in the Sierra, chapter V, "The Yosemite" (Passage 1: July 20, Billy the shepherd) (1911; this edition 1916). Public domain (published 1916). Source text.
    • Explicit: the direct statement beats the hint

      Claim: Billy never takes off his clothes. Two candidates: "his wonderful everlasting clothing" (paragraph 1) and "These precious overalls are never taken off" (paragraph 1). Which is stronger?

      Result: "These precious overalls are never taken off" is stronger. Both are on target, but "everlasting" only hints that the clothes last a long time; a reader could take it as praise for tough cloth. The second quotation states the claim in almost the same words, so it is specific and decisive. The first becomes the runner-up.

    • Explicit: the one that names the details

      Claim: Muir has his own camp chores. Candidates: "these small duties done" and "I have agreed to wash the few iron and tin utensils and make the bread" (both paragraph 2).

      Result: The second is stronger because it is specific: it names the two chores, washing the pots and pans and making the bread, and it shows they are Muir's ("I have agreed"). "these small duties" is on target but vague; without the sentence before it, a reader could not tell whose duties they are or what they were.

    • Inference: ranking three candidates

      Muir never says "I am joking." Claim: he is poking fun at Billy, not writing a science report. Candidates: "Our shepherd is a queer character"; "he collects fragmentary specimens of everything and becomes richer than he knows"; "in their stratification have no small geological significance" (all paragraph 1).

      Result: Weakest: "queer character" shows that Billy is odd, not that Muir is joking. Stronger: calling the dirt on the trousers "specimens" is playful. Strongest: "stratification" and "geological significance" describe greasy trousers as if they were layers of rock worth a scientist's study. That serious language only makes sense as a joke, so this quotation is decisive (Diagram 1).

    • Inference: a contrast inside one sentence

      Muir never says what he thinks of the sheep job. Claim: he cares far more about exploring than about his camp work. Which evidence settles it?

      Result: "these small duties done, by the time the sun is fairly above the mountain-tops I am beyond the flock, free to rove and revel in the wilderness all the big immortal days" (paragraph 2). The chores are "small"; the days in the wilderness are "big" and "immortal," and he finishes the chores early to reach them. A weaker choice, "Besides herding the sheep, Billy is the butcher," is about Billy's jobs and says nothing about how Muir feels.

    Claim, candidates, choice, reason. Show Diagram 1 and model the four moves with the third example: state the claim; list two or three candidate quotations; run the strength test on each; then write one sentence that names the winner and one that says why it beats the runner-up. Give students two sentence frames: "The strongest evidence that ___ is ___ (paragraph __), because it is the only one that ___." and "The quotation ___ is also on target, but it is weaker because ___."

  3. Guided Practice15 minutes

    Read Passage 2 aloud. It is the next day, July 21, and the start of the story students will follow into Passage 3. Words to know: Dome (North Dome, a rounded granite peak above Yosemite Valley where Muir sat to sketch), to advantage (in the best way), moraine boulders (rocks left behind by a glacier), mountaineer (here, a creature that lives in the mountains), buttresses (the wide, spreading base of a tree trunk), Bruin (an old nickname for a bear, from stories) and a stone's throw (as far as a person can throw a stone, a short distance).

    Saw a common house-fly and a grasshopper and a brown bear. The fly and grasshopper paid me a merry visit on the top of the Dome, and I paid a visit to the bear in the middle of a small garden meadow between the Dome and the camp where he was standing alert among the flowers as if willing to be seen to advantage. I had not gone more than half a mile from camp this morning, when Carlo, who was trotting on a few yards ahead of me, came to a sudden, cautious standstill. Down went tail and ears, and forward went his knowing nose, while he seemed to be saying, “Ha, what’s this? A bear, I guess.” Then a cautious advance of a few steps, setting his feet down softly like a hunting cat, and questioning the air as to the scent he had caught until all doubt vanished. Then he came back to me, looked me in the face, and with his speaking eyes reported a bear near by; then led on softly, careful, like an experienced hunter, not to make the slightest noise; and frequently looking back as if whispering, “Yes, it’s a bear; come and I’ll show you.” Presently we came to where the sunbeams were streaming through between the purple shafts of the firs, which showed that we were nearing an open spot, and here Carlo came behind me, evidently sure that the bear was very near. So I crept to a low ridge of moraine boulders on the edge of a narrow garden meadow, and in this meadow I felt pretty sure the bear must be. I was anxious to get a good look at the sturdy mountaineer without alarming him; so drawing myself up noiselessly back of one of the largest of the trees I peered past its bulging buttresses, exposing only a part of my head, and there stood neighbor Bruin within a stone’s throw, his hips covered by tall grass and flowers, and his front feet on the trunk of a fir that had fallen out into the meadow, which raised his head so high that he seemed to be standing erect. He had not yet seen me, but was looking and listening attentively, showing that in some way he was aware of our approach. I watched his gestures and tried to make the most of my opportunity to learn what I could about him, fearing he would catch sight of me and run away.

    Pairs use the strength chart (Diagram 2) for two claims. For each one, they give every candidate a check or a cross for on target, specific and decisive, rank the four, and write one sentence on why the winner beats the runner-up. Take answers, then share the teacher notes:

    1. Claim A (explicit): the bear was close to Muir when Muir first saw him. Candidates: (1) "standing alert among the flowers"; (2) "there stood neighbor Bruin within a stone’s throw"; (3) "in this meadow I felt pretty sure the bear must be"; (4) "the sunbeams were streaming through between the purple shafts of the firs." Teacher note: (2) wins. It is the only candidate that gives a distance, and "a stone's throw" is short. (3) is the runner-up: it places the bear in the meadow, but it is a guess made before Muir saw him and gives no distance. (1) is about the bear's pose, and (4) is off target (the light in the forest).
    2. Claim B (inference): Carlo knew a bear was there before Muir did. Candidates: (1) "came to a sudden, cautious standstill"; (2) "questioning the air as to the scent he had caught until all doubt vanished"; (3) "with his speaking eyes reported a bear near by"; (4) "Carlo, who was trotting on a few yards ahead of me." Teacher note: (3) wins, because Carlo comes back to report the bear while Muir has seen nothing yet. (2) is the runner-up: it shows Carlo picking up a scent, but not yet what the scent was. (1) is on target but not decisive, since a dog can stop for many reasons, and (4) only gives Carlo's position.
    3. Check the reasoning. Ask pairs: every candidate in Claim B comes from Muir, who could not read the dog's mind. Does that weaken the evidence? Teacher note: it means the evidence supports an analysis of what Muir reports. The strongest quotation is still the one that shows Carlo acting on what he knew, and a careful answer says "Muir shows that Carlo knew..." rather than claiming to know the dog's thoughts.
  4. Independent Practice15 minutes

    Students read Passage 3 on their own. It continues the same paragraph as Passage 2, and three short cuts are marked [...]. Words to know: cinnamon (a cinnamon bear, a black bear with a reddish-brown coat), his bad brother man (Muir's phrase for human beings, seen from the bear's side), muzzle (nose and mouth), gait (way of moving), dismay (sudden worry and disappointment), fervently (with strong feeling), strenuous (tense and hard), deliberation (slow care), ungovernable (impossible to control), whose lines have fallen in pleasant places (who has a lucky life, a phrase from the Bible), cañons (canyons), reigns supreme (rules over all), the Don's rifle (Mr. Delaney's rifle) and bade him Godspeed (wished him a safe journey).

    For I had been told that this sort of bear, the cinnamon, always ran from his bad brother man, never showing fight unless wounded or in defense of young. [...] After examining at leisure, noting the sharp muzzle thrust inquiringly forward, the long shaggy hair on his broad chest, the stiff, erect ears nearly buried in hair, and the slow, heavy way he moved his head, I thought I should like to see his gait in running, so I made a sudden rush at him, shouting and swinging my hat to frighten him, expecting to see him make haste to get away. But to my dismay he did not run or show any sign of running. On the contrary, he stood his ground ready to fight and defend himself, lowered his head, thrust it forward, and looked sharply and fiercely at me. Then I suddenly began to fear that upon me would fall the work of running; but I was afraid to run, and therefore, like the bear, held my ground. We stood staring at each other in solemn silence within a dozen yards or thereabouts, while I fervently hoped that the power of the human eye over wild beasts would prove as great as it is said to be. How long our awfully strenuous interview lasted, I don’t know; but at length in the slow fullness of time he pulled his huge paws down off the log, and with magnificent deliberation turned and walked leisurely up the meadow, stopping frequently to look back over his shoulder to see whether I was pursuing him, then moving on again, evidently neither fearing me very much nor trusting me. He was probably about five hundred pounds in weight, a broad, rusty bundle of ungovernable wildness, a happy fellow whose lines have fallen in pleasant places. [...]

    In the great cañons Bruin reigns supreme. [...] I should like to know my hairy brothers better—though after this particular Yosemite bear, my very neighbor, had sauntered out of sight this morning, I reluctantly went back to camp for the Don’s rifle to shoot him, if necessary, in defense of the flock. Fortunately I couldn’t find him, and after tracking him a mile or two towards Mount Hoffman I bade him Godspeed and gladly returned to my work on the Yosemite Dome.

    John Muir, My First Summer in the Sierra, chapter V, "The Yosemite" (Passage 3: July 21, face to face; three short cuts marked [...]) (1911; this edition 1916). Public domain (published 1916). Source text.

    On the handout, students (1) describe what the bear looked like up close, citing the most specific evidence in paragraph 1; (2) explain how Muir's feelings toward the bear changed between the rush and the end of the morning, citing the strongest quotation for each feeling and saying why each beats a runner-up; (3) decide which quotation more strongly supports the claim the bear was not afraid of Muir: "he stood his ground ready to fight and defend himself" or "He was probably about five hundred pounds in weight," and explain using the strength test. The quiz uses Passages 1-3.

  5. Closure5-10 minutes

    Exit ticket: (1) In one sentence, explain the difference between evidence that is on target and evidence that is decisive. (2) Claim: Muir admired the bear. Choose the single strongest quotation from Passage 3 and write one sentence on why it beats another quotation you considered.

    Teacher note on history, language and safety: Muir wrote in 1869 and published in 1911, and some words have changed meaning since then: "queer" here means strange, and Muir uses it for the grasshopper in Passage 4 as well. He describes animals as if they had human thoughts and speech; ask students to treat those lines as Muir's interpretation. Safety: Muir's rush at the bear is exactly what park rangers today tell visitors never to do. Current National Park Service advice is to keep your distance (Yosemite asks visitors to stay at least 50 yards away), never approach or chase a bear, and never run from one; instead, stand your ground, make yourself look as large as possible, talk calmly and back away slowly. Say this plainly before students discuss Passage 3. Grazing large flocks of sheep in the high Sierra, the job Muir took that summer, was later limited when Yosemite became a national park, partly because of Muir's own writing.

    For homework: students read Passage 4, printed below. It comes from the afternoon of the same day, July 21, when Muir was back at his sketching on the Dome. Two short cuts are marked [...]. Words to know: excursions (short trips), brimful (full to the top), hilarious (here, cheerful and merry), alighted (landed), described (here, traced a shape in the air), redlegs (Muir's nickname for the grasshopper), gayety (an older spelling of gaiety, cheerfulness), sublime (grand enough to fill you with awe), dejection and melancholy (sadness), no winter of discontent (no time of unhappiness, a phrase from Shakespeare) and I fancy (I imagine).

    A queer fellow and a jolly fellow is the grasshopper. Up the mountains he comes on excursions, how high I don’t know, but at least as far and high as Yosemite tourists. I was much interested with the hearty enjoyment of the one that danced and sang for me on the Dome this afternoon. He seemed brimful of glad, hilarious energy, manifested by springing into the air to a height of twenty or thirty feet, then diving and springing up again and making a sharp musical rattle just as the lowest point in the descent was reached. Up and down a dozen times or so he danced and sang, then alighted to rest, then up and at it again. The curves he described in the air in diving and rattling resembled those made by cords hanging loosely and attached at the same height at the ends, the loops nearly covering each other. Braver, heartier, keener, care-free enjoyment of life I have never seen or heard in any creature, great or small. The life of this comic redlegs, the mountain’s merriest child, seems to be made up of pure, condensed gayety. [...] Wonderful that these sublime mountains are so loudly cheered and brightened by a creature so queer. Nature in him seems to be snapping her fingers in the face of all earthly dejection and melancholy with a boyish hip-hip-hurrah. How the sound is made I do not understand. When he was on the ground he made not the slightest noise, nor when he was simply flying from place to place, but only when diving in curves, the motion seeming to be required for the sound; for the more vigorous the diving the more energetic the corresponding outbursts of jolly rattling. I tried to observe him closely while he was resting in the intervals of his performances; but he would not allow a near approach, always getting his jumping legs ready to spring for immediate flight, and keeping his eyes on me. [...] No danger of weakness in the knees of the world while Nature can spring such a rattle as this. Even the bear did not express for me the mountain’s wild health and strength and happiness so tellingly as did this comical little hopper. No cloud of care in his day, no winter of discontent in sight. To him every day is a holiday; and when at length his sun sets, I fancy he will cuddle down on the forest floor and die like the leaves and flowers, and like them leave no unsightly remains calling for burial.

Differentiation Strategies

For Struggling Students

  • Give the strength test as a three-box card (On target? Specific? Decisive?) that students tick for each candidate before they rank
  • Start with two candidates instead of four, one clearly strong and one on the topic but off target, and add candidates as students gain confidence
  • Pre-teach the six hardest words in Passage 1 with pictures (stalactites, corral, six-shooter, resin, rock layers, a museum specimen drawer)

For Advanced Students

  • Ask them to find a quotation in Passage 3 that could support two opposite claims, and explain what extra evidence would decide between them
  • Have them write a claim about Muir that only the combination of two quotations can prove, and explain why neither one is enough alone
  • Ask them to compare what Muir says about the bear in Passage 3 with what he says about the grasshopper in Passage 4, and decide, with the strongest evidence from each, which animal he admired more

Assessment Guidance

What to Look For

Check that each answer names one winning quotation with its passage and paragraph number and gives a reason tied to the strength test, not "it is the best one." Watch for three common problems: choosing a quotation that is on the topic but not on the claim (the forest light instead of the bear's distance), choosing the longest quotation because it seems to contain more, and treating Muir's guesses about what an animal thinks as facts. For inferences, look for a sentence that explains why the winner settles the question and the runner-up does not.

Classroom Activities

3 Activities

1

Evidence Tournament

15 minPairs

Pairs run a four-card tournament for one claim about Passage 1. In each match, two quotation cards meet and the stronger one moves on; the pair must write the reason for every win. The goal is to see that the final winner is the card that covers every part of the claim.

The Claim and the Four Cards

Claim: Billy's clothes are soaked with grease from his lunch.

  • Card 1: "The ancient cloth in which the meat, fresh from the frying-pan, is tied serves as a filter through which the clear fat and gravy juices drip down on his right hip and leg"
  • Card 2: "His bed is a hollow made in red dry-rot punky dust beside a log"
  • Card 3: "making shirt and trousers water-tight and shiny"
  • Card 4: "Man is a microcosm, at least our shepherd is, or rather his trousers"

Procedure

  • Match 1: Card 1 against Card 2. Match 2: Card 3 against Card 4. Final: the two winners
  • For every match, pairs write which card wins and which of the three test questions decided it
  • Answer key for the teacher: Card 1 beats Card 2 (Card 2 is about his bed, so it is off target). Card 3 beats Card 4 (Card 4 is a general joke about the trousers; Card 3 is a specific result on the clothes). In the final, Card 1 wins because it is the only card that connects the grease to the lunch, the meat "fresh from the frying-pan," and shows it dripping onto his clothes. Card 3 shows the clothes are greasy but not where the grease came from, so it is the runner-up

Discussion Questions

  • Card 3 is shorter than Card 1. Did length decide the final? What did?
  • Change one word in the claim so that Card 3 would win the final.
  • Card 4 is funny and about the trousers. Why does it still lose?

Modification

For students who need support, play only the final: give pairs Cards 1 and 3 and the question "Which card shows where the grease came from?"

2

Weak, Stronger, Strongest

15 minGroups of 3-4

Each group gets three claim cards and nine quotation strips, three for each claim. Every strip is on the topic, so the group must order each set on a paper ladder from weak to strongest and label the rung with the test question that moved it up.

The Three Claims and Their Strips

  1. Muir's plan to make the bear run did not work (Passage 3). Strips: "How long our awfully strenuous interview lasted, I don’t know"; "Then I suddenly began to fear that upon me would fall the work of running"; "But to my dismay he did not run or show any sign of running."
  2. The bear still did not trust Muir as he left (Passage 3). Strips: "In the great cañons Bruin reigns supreme"; "looked sharply and fiercely at me"; "stopping frequently to look back over his shoulder to see whether I was pursuing him."
  3. Billy's trousers have collected bits of nature (Passage 1). Strips: "Man is a microcosm, at least our shepherd is, or rather his trousers"; "His specimens are kept passably fresh"; "pine needles, thin flakes and fibres of bark, hair, mica scales and minute grains of quartz" (part of the long list in paragraph 1).

Procedure

  • Groups place the strips for each claim on the ladder, bottom to top, and write "on target," "specific" or "decisive" beside each step up
  • Answer key for the teacher: each list above is already in order from weak to strongest. Claim 1: the first strip shows only that the moment was tense, the second shows Muir afraid, and the third states that the bear did the opposite of what he expected. Claim 2: the first strip is general, the second shows distrust during the standoff but not as he left, and the third shows him checking on Muir while walking away. Claim 3: the first strip is a general joke, the second mentions "specimens" without naming any, and the third names real things from the forest

Discussion Questions

  • For claim 1, the middle strip is about Muir's fear. Why is it weaker than the top strip for this claim, even though it is interesting?
  • For claim 2, what word in the claim ("as he left") pushed the top strip above the middle one?
  • Write a new claim for which the bottom strip of set 2 would be the strongest evidence.
3

Upgrade the Evidence

10 minPairs

Pairs read three short student answers (written for this activity) whose quotations are accurate but weak. They replace each quotation with the strongest one they can find and write one sentence on what the upgrade fixes.

The Three Student Answers

  1. "The bear was partly hidden by plants. Muir says he was 'standing alert among the flowers' (Passage 2)."
  2. "The bear was somewhere between Muir's camp and the Dome. Muir writes, 'there stood neighbor Bruin within a stone’s throw' (Passage 2)."
  3. "Billy sleeps right next to the sheep pen. The text says, 'Here he lies with his wonderful everlasting clothing on, wrapped in a red blanket' (Passage 1, paragraph 1)."

Procedure

  • Pairs say which test question each quotation fails, then find a replacement in the same passage
  • Answer key for the teacher: (1) "among the flowers" does not say the plants hid him; upgrade to "his hips covered by tall grass and flowers." (2) "within a stone’s throw" gives his distance from Muir, not his place between two landmarks; upgrade to "in the middle of a small garden meadow between the Dome and the camp." (3) the quotation shows Billy lying down but not where; upgrade to "beside a log which forms a portion of the south wall of the corral"

Variation

For a harder version, pairs write their own weak-evidence answer about Passage 2 and trade with another pair, who must upgrade it.

Diagrams & Visual Aids

2 diagrams

Diagram 1: Ranking Evidence for One Inference

Weak, stronger, strongest: one inference, three candidates Claim: Muir is poking fun at Billy (Passage 1, paragraph 1) On target Specific Decisive Strongest "in their stratification have no small geological significance" Serious science words for greasy trousers: only a joke fits Stronger "he collects fragmentary specimens of everything" Playful, but could be read as a plain description Weak "Our shepherd is a queer character" Shows Billy is odd, not that Muir is joking Each step up passes one more test question. Name the winner and say why it beats the runner-up.
The third worked example as a ladder. All three quotations from Passage 1 are accurate and about Billy, but each step up passes one more question of the strength test. Only the top one is decisive, because serious science words make sense for greasy trousers only as a joke.

RI.8.1 Homework: The Grasshopper on the Dome

Directions: Read Passage 4 at the end of the lesson plan (in Closure). It is one paragraph, so cite it as (Passage 4); cite the other passages by passage and paragraph number. For every answer, give the single strongest quotation first, in quotation marks, and then explain your choice.

Part 1: The Strongest Evidence for What the Text Says (Problems 1-2)

  1. How high did the grasshopper spring into the air? Quote the strongest evidence, and explain why a quotation such as "Up and down a dozen times or so he danced and sang" does not answer this question.
  2. Muir says the grasshopper made "a sharp musical rattle." When did it make the sound, and when was it silent? Choose between "making a sharp musical rattle just as the lowest point in the descent was reached" and the sentence that begins "When he was on the ground," and explain which one more strongly supports a complete answer.

Part 2: The Strongest Evidence for an Inference (Problems 3-4)

  1. Muir never writes "The grasshopper was the best thing I saw today." What can you infer about how he ranked the grasshopper against the bear he met that morning? Cite the one quotation from Passage 4 that settles the question, and explain why it is decisive.
  2. What can you infer about whether Muir watched the grasshopper as a scientist or only as an admirer? Support your inference with the strongest quotation, then name a runner-up and explain why it is weaker.

Part 3: Choosing and Defending (Problems 5-6)

  1. Claim: Muir enjoyed the grasshopper's company. Rank these three quotations from weakest to strongest and explain each step: (a) "Up the mountains he comes on excursions"; (b) "I was much interested with the hearty enjoyment of the one that danced and sang for me"; (c) "A queer fellow and a jolly fellow is the grasshopper."
  2. Write a paragraph of 6-8 sentences answering: What kind of observer of animals does Muir show himself to be in Passages 2, 3 and 4? Make one explicit claim and one inference. For each, give the strongest quotation with its passage and paragraph number and explain why it beats a runner-up you considered.

Frequently Asked Questions

10 Questions

What does RI.8.1 mean?

It means eighth graders must support what they say about a nonfiction text with the evidence that proves it best. The standard asks for "the textual evidence that most strongly supports an analysis" of both what the text "says explicitly" and the "inferences drawn from the text." Students choose among possible quotations, cite the strongest one, and explain why it is the strongest.

How is RI.8.1 different from RI.7.1?

RI.7.1 asks for "several pieces of textual evidence"; RI.8.1 asks for the evidence that "most strongly supports" the analysis. In grade 7, students gather more than one piece for each claim. In grade 8, they judge the pieces against each other and defend their choice. High school (RI.9-10.1) then asks for evidence that is "strong and thorough."

What makes one piece of evidence stronger than another?

Strong evidence passes three tests. It is on target (about this exact claim, not just the same topic), specific (a concrete action, detail or statement) and decisive (hard to read any other way). A quotation can be accurate and interesting and still lose to one that settles the question more clearly.

Does the strongest evidence mean the longest quotation or the most quotations?

No. A long quotation often carries extra words that do not help, and a short phrase can be decisive. Students may combine two quotations when the claim has two parts, but each one should do work the other cannot. Ask students to trim every quotation to the words that prove the point.

What is the difference between RI.8.1 and RL.8.1?

The skill is the same; the texts differ. RL.8.1 is for stories, poems and plays, and RI.8.1 is for informational texts such as journals, articles, speeches and science writing. In nonfiction the strongest evidence is often a stated fact, a number or the author's own direct statement, while in fiction it is often a character's action or words.

How do I teach students to choose between two good quotations?

Make them name a runner-up. After students pick their best quotation, ask for the second-best and one sentence on why it lost. That sentence forces them to use the tests: "It is on target, but it does not show where the grease came from." Tournament brackets and weak-to-strongest ladders give quick, low-stakes practice.

Can a writer's opinion or guess be strong evidence?

Yes, for a claim about what the writer thinks. When Muir writes that Carlo "seemed to be saying, “Ha, what’s this? A bear, I guess,”" the quotation is strong evidence of how Muir read the dog’s behavior, but weak evidence of what the dog actually thought. Students should say which claim the quotation supports and use words such as "Muir believes" or "Muir imagines."

How is RI.8.1 assessed on tests?

Many state reading tests pair questions: the first asks for an answer about a passage, and the second asks which quotation best supports that answer. Several choices in the second part are usually accurate and on the topic, so students need the habit of asking which one proves the answer. Written responses are also scored on whether the evidence fits the claim.

Why use John Muir's My First Summer in the Sierra to teach RI.8.1?

It is a real journal, in the public domain, with short entries full of concrete details, funny exaggeration and dramatic moments like the bear standoff. Muir often mixes what he saw with what he imagined an animal was thinking, which gives students steady practice in separating strong evidence from weak.

How can parents help a child practice RI.8.1 at home?

Play "prove it" with everyday reading. After a news story, a game review or a recipe, ask your child to make one claim about it and point to the single sentence that proves it best, then ask "What is the second-best sentence, and why did it lose?" Short, frequent rounds build the habit.
