Teacher Answer Key – Final Page
1. It is small and round.
2. It can roll across a desk.
3. A ball. Accept answers such as “a small red ball” when supported by the clues.
4. Answers will vary. Look for a small, round, red object, preferably with a label showing one detail.
Clue → What I think → Why: Accept sensible inferences supported by the text. For example, “small and round” may suggest a ball; “smooth, red and shiny” may suggest a red ball; “can roll” strongly suggests a ball or another round object.
Vocabulary: clue – a helpful sign or detail; whisper – quiet words; parcel – a package; hidden – kept out of sight; curious – wanting to find out more.
5. Accept small, round, smooth or red.
6. roll or rolls.
7–8. Answers will vary. Check that the student has replaced a vague word with a clearer adjective or verb and has completed the checklist honestly.
