Success: use evidence to respond to a counterclaim without a straw person. Prepare Text C and factor array. (AC9E5LA02, AC9E5LY02, AC9E5LY06)
- Recall · 2 min. Ask what five equal boxes of 36 would require. Accept “check divisibility” rather than guessing.
- Model · 4 min. State fairly: “The volunteer may want to use fewer boxes.” Then: “But 36 is not divisible by five into equal whole books; cost is unknown.”
- Guided comparison · 5 min. Contrast “That volunteer is silly” with the model. Learners identify which sentence addresses the decision and which attacks a person.
- Independent response · 7 min. Write a three-sentence reply: recognise the fewer-box goal, use one mathematical fact, ask for one missing cost or availability fact.
- Source check · 4 min. Pairs underline the given fact and mark an unprovided assertion with a question mark. Teacher checks one complete response per focus learner.
- Exit · 3 min. “Can four boxes of nine be equal?” Key: yes mathematically, but those boxes are not yet available.
