Target/codes: compare a changing two-panel story with a grouped repeating visual unit as art structures; AC9AVAFD01. Prepare: sequence or repeat, exact text/tactile route.
- Welcome · 3 min. Recall a two-panel picture where something changed. Ask what might happen if a small group of marks came back again and again.
- Model · 4 min. Show OPEN BOX then CLOSED BOX as one invented story change. Separately show ARCH, BAR | ARCH, BAR. Mark the unit boundary. Do not call a one-time change a repeat.
- Try together · 5 min. Child points, says, signs or directs where the repeated group begins/ends and which box state changed. A wrong guess prompts another exact reading, not a neatness judgement.
- Child choice · 7 min. Child chooses whether an imaginary page needs a changing picture or repeating marks, and states a viewer purpose. They can sketch, direct two broad forms or use the optional no-material description. If they choose a repeat, invite another whole unit without a colour-only cue.
- Notice · 4 min. Record art intention separately from mathematical recognition of a whole repeating unit; the mathematics pack gathers its own evidence.
- Close · 2 min. “My page changes/returns because I want a viewer to ___.”
