Goal: independently identify what a new three-frame paper case shows and what it cannot show. Proposed codes: AC9SFU02 (representation only), AC9SFH01, AC9SFI03. Prepare: unseen teacher-held Case AB, blank claim mat, Card 125 only after response.
- Preflight · 3 min. Confirm AB has not appeared in lessons, swaps or print aids; choose literal read-aloud, large print, AAC or broad fixed tactile route.
- Present · 4 min. Read the complete FICTIONAL PAPER CASE once; do not point to its missing route detail.
- Think · 5 min. Offer quiet independent time; log a neutral exact reread if requested.
- First independent response · 7 min. Child orders the pictured positions, says what remains unknown and proposes a safe real source. Record first words/access/prompts before feedback.
- Bound · 4 min. Ask what would need to be actually observed and dated to know a real route. Paper-only remains REAL OBSERVATION NOT AVAILABLE.
- Close · 2 min. Use separate key afterwards for the next teaching move; Card 125 comes later.
