Target/codes: independently create two visual strip options from a fresh two-mark source, choose one for an intended art effect and keep any claimed unit honest; AC9AVAFD01 and AC9AVAFC01. Prepare: Check N, large page, separate educator key closed.
- Welcome · 3 min. “Two unfamiliar marks; your art choices matter. You can answer without making a sound or touching a card.”
- Model access · 4 min. Read only the source mark names and blank unit/strip spaces. On unrelated paper show speech, AAC, sign, drawing, pointing or neutral scribe access, without making a held repeat.
- Independent plan · 5 min. Child chooses a two-mark order and two ways to group/show it; no adult choice hint.
- Child response · 7 min. Child gives two distinct strip options with at least two complete repeats of their chosen unit, chooses one and states what they want a viewer to notice. They identify actual handler or PLAN ONLY.
- Self-check · 4 min. Ask the child to point to one whole repeated part and a space/scale choice. Collect first response before key or corrective teaching.
- Close · 2 min. Keep art intention separate from the mathematics teacher's pattern judgement and any later audience share.
