Context Clues in a Science Paragraph
A Grade 3 class is reading a short science paragraph about how some animals survive winter. The target sentence reads: Some frogs become dormant in cold weather; their bodies slow down so much that they barely use any energy until spring. Three students are asked what dormant means. Student 1 says 'sleeping.' Student 2 says 'dead.' Student 3 says 'moving slowly.' The teacher wants to use their answers to teach students how to use the sentence itself, not a dictionary, to check a meaning. The paragraph also uses energy and survive, and the teacher knows some students confuse dormant with hibernation, a word they learned in a previous unit.
1. Evaluate each student's answer using only the clues in the sentence.

Student 1's 'sleeping' is close but not fully supported: the sentence says bodies slow down and barely use energy, which fits a sleep-like state, but 'sleeping' is a guess unless checked against the rest of the sentence. Student 2's 'dead' is contradicted by the sentence, which says the frog's body slows down until spring, implying it resumes activity; a dead animal would not have a spring return. Student 3's 'moving slowly' is only partly supported: the sentence emphasizes low energy use and slowed body function, not movement specifically. The best-supported meaning is a slowed, low-energy resting state that ends in spring. A strong answer names which words in the sentence do the work: slow down, barely use any energy, and until spring.
2. How should the teacher handle the *dormant* versus *hibernation* confusion?
Read the worked answer
The teacher should treat the two words as related but not identical, and use the text to draw the line rather than giving a definition to memorize. Hibernation is the familiar word students already own; dormant is the new word the author chose. The teacher can ask: 'The author could have written hibernate. What does dormant add or leave out here?' Students should notice that the sentence describes a slowed, low-energy state without saying the frog is fully asleep for the whole season. The goal is for students to see that a new word can overlap with a known word without being a perfect swap, and that the sentence, not the earlier unit, decides the meaning here.
3. What follow-up task would show whether students can apply the strategy to a new word?
Read the worked answer
Give students a new sentence with an unfamiliar word and a built-in clue, and ask them to underline the clue words and write a meaning. For example: The turtle burrows into the mud and stays still, using almost no energy, until the warm days return. Students should underline stays still, almost no energy, and until the warm days return, then write a meaning close to 'resting in a low-energy way.' The task works because it cannot be answered from memory of the earlier paragraph; students must locate the clue and reason from it. The teacher should check the underlined clues as well as the written meaning, since a right answer with no clue marked may be a lucky guess.
