Goal: compare two possible drawn paths and explain why the stills alone do not select one. Proposed codes: AC9SFU02 (representation only), AC9SFH01, AC9SFI03. Prepare: solid/dashed route picture, F and G, Card 122.
- Recall · 3 min. Revisit F's three stations; label all paper paths FICTIONAL MODEL.
- Trace · 4 min. Read G's solid horizontal route, then dashed upper-bend route in that order.
- Adult model · 5 min. Cover the connecting lines: both routes now leave the same three station pictures. A still cannot reveal which connecting path was taken.
- Child try · 7 min. Card 122 routes trace, describe or direct both routes; child points to the same three stations and states “both could fit” or equivalent.
- Probe · 4 min. Ask if a bend in a drawing proves an actual square turned. Record “model only” or repair with a neutral prompt.
- Exit · 2 min. Keep two possible routes, no selected real route.
