Target/codes: independently change one final frame in a new three-frame circle sequence while holding frames 1–2; AC9AMAFD01, AC9AMAFC01, AC9AMAFP01 only for actual sharing. Prepare: new H public check, H A4, large circle positions. Keep key closed until first response.
- Welcome · 3 min. Introduce new circle frames for a fictional paper stage; this is a public teaching probe, not a photography task.
- Access · 4 min. Present starting CIRCLE LEFT, MIDDLE, RIGHT and the maker's wish for the circle to return LEFT at the end. Do not suggest which frame to alter.
- Independent plan · 5 min. Child identifies held frames 1–2 and chooses one final-position change.
- Child response · 7 min. Child shows all three frames and a possible reason by selected route. Record first choice and any actual willing recipient separately.
- Self-check · 4 min. Invite the child to point to the frame changed and the two held frames, without supplying the answer.
- Close · 2 min. Save first response, then consult key and plan later real media encounters and broader production opportunities.
