Target/codes: independently change one line in a new two-line image for a specified fictional purpose; AC9AVAFD01, AC9AVAFC01. Prepare: new G public check, G A4, broad line cards. Keep teacher key closed until first response.
- Welcome · 3 min. Explain this new paper puzzle helps plan the next art session, not a test of drawing neatness.
- Access · 4 min. Present two straight horizontal lines labelled TOP and BOTTOM neutrally. A tactile raised-line route is available; do not indicate the change.
- Independent plan · 5 min. Child chooses the one line to curve so the bottom path bends but the top stays straight.
- Child response · 7 min. Child shows both lines, marks the change and gives a reason by a chosen route; a neutral adult records the first response.
- Self-check · 4 min. Invite the child to name TOP/BOTTOM and what stayed. Do not coach or score material control from a paper plan.
- Close · 2 min. Save first response before opening the key. Day 5 supplementary swaps use other line images after the check.
