What RI.3.1 Means in Plain English
Third graders answer questions about nonfiction and show where in the text each answer comes from. A student who says a camel’s hump stores water is answering from memory, and the passage says otherwise. The habit to build: “The text says…” followed by the line itself.
Second graders (RI.2.1) answered who, what, where, when, why and how questions about key details. Third grade adds the proof: every answer points back to the words on the page. Fourth grade (RI.4.1) uses details and examples to support inferences, not just what the text states.
RI.3.1 I Can Statements
- I can answer a question using facts from the text.
- I can point to the sentence that proves my answer.
- I can ask questions that the text can answer.
RI.3.1 Worked Example
The question tempts students to answer from what they think they already know, and only the strong answer goes back to the passage.
Many people think a camel’s hump is a tank full of water. It is not. The hump is full of fat.When food is hard to find, the camel’s body uses that fat for energy. A camel that has gone a long time without eating has a hump that is small and floppy.Camels save water in other ways. A camel hardly sweats, even on a hot day. Instead, its body slowly warms up during the day and cools off at night.When a thirsty camel finally finds water, it can drink more than 20 gallons in one visit.
Common Mistakes with RI.3.1
Answering from memory
“Camels keep water in their humps.”
Try this: Ask “Where does the text say that?” every time, and accept an answer only when the student can read the sentence aloud.
Pointing to the whole page
“It’s somewhere in there,” with a finger on the passage, not on a line
Try this: Have students underline the exact words that prove the answer and number the line, so the proof is one sentence, not a page.
Questions the text can’t answer
“How many camels live in the world?” asked about a passage that never says
Try this: Teach students to check that the passage holds the answer before they ask, and park other questions on a wonder list.
