Target/codes: independently preserve four pulse places and relocate a single planned accent under a new constraint; AC9AMUFD01, AC9AMUFC01. Prepare: I public check, I A4, broad cards. Keep the separate key closed until first responses.
- Welcome · 3 min. Say this new paper puzzle helps choose later teaching. It does not test loudness, hearing or physical timing.
- Access · 4 min. Present the exact starting four-X score with its star at count 2 using print, raised marker or neutral read-aloud. Do not hint at the destination.
- Independent plan · 5 min. Child decides how to keep four X while placing the one star on the last count for the fictional picture-map visitor.
- Child response · 7 min. Child marks, points, uses AAC or directs a neutral adult; save the first placement and their reason. Optional sound comes after the independent plan.
- Self-check · 4 min. Ask child to count X marks and stars, then indicate which count is last. No corrective cue before first response is stored.
- Close · 2 min. Consult the teacher key afterward; check-day supplementary swaps use unrelated rows.
