Target/codes: keep a chosen visual unit recognisable while mapping it to a safe silent action and back; AC9AVAFD01 and AC9AVAFC01. Prepare: quiet transfer, optional offline visual strip, local movement/access check.
- Welcome · 3 min. Invite a seated, still, non-contact route. No child must perform, hear a rhythm, make a sound or touch another person.
- Model · 4 min. Show original ARCH, BAR as marks. Suggest a silent raised-hand cue for ARCH and still hand for BAR, then redraw ARCH, BAR. Call the action mapping one invented option, not a universal sign.
- Try together · 5 min. Child proposes or chooses two distinguishable safe actions, AAC symbols or adult-described cues. Adult repeats the mapping and asks whether the ordered unit stayed the same when it returned to marks.
- Child choice · 7 min. Child translates their own Day 37 visual unit to an approved quiet action/tabletop sequence and back to a new strip, or directs an adult with no movement. They choose one art revision in spacing or scale while preserving mark order if claiming the same unit.
- Notice · 4 min. Record the original and returned visual order, exact child mapping, chosen art revision and actual mover/marker. Do not claim Music/Dance achievement or an independent maths transfer from a prompted imitation.
- Close · 2 min. Ask which version they would show a viewer and why.
