Goal: independently apply a new paper-feature rule, find a counterexample and state the real-evidence limit. Proposed codes: AC9SFU01 (model reasoning), AC9SFI03, AC9SFI05. Prepare: unseen teacher-held Case AF, blank revision board; Card 145 follows the first response.
- Preflight · 3 min. Keep AF unseen; set exact read-aloud, large print or broad secured tactile alternative.
- Present · 4 min. Read the complete new FICTIONAL PAPER CASE once without pointing to the counterexample.
- Think · 5 min. Give quiet independent time; record any neutral exact reread.
- First independent response · 7 min. Child sorts by the stated feature, identifies the conflicting author label, revises the claim and distinguishes drawing from real plant/animal evidence.
- Bound · 4 min. Ask what distinct real sources and dates would be needed to test the idea outside the paper case. Paper route remains REAL OBSERVATION NOT AVAILABLE.
- Close · 2 min. Use the separate key only after the first response; reteach later with Card 145.
