- Welcome · 3 min. Explain that this new paper music puzzle guides later teaching. It is not a test of hearing, motor timing or real postcards.
- Access · 4 min. Present PULSE
X X X Xand starting RHYTHM– X – Xneutrally by print, tactile cells or read-aloud. Do not hint where to add the sound. - Independent plan · 5 min. Child keeps rhythm X at 2 and 4, keeps beat 3 quiet, and decides where one new short X goes so the rhythm has three sound events.
- Child response · 7 min. Save first full two-row score, changed count and reason through cards, drawing, AAC, pointing or neutral adult scribe. Optional sound can follow the plan.
- Self-check · 4 min. Ask the child to count four beat places and three rhythm sounds without giving feedback before first response is captured.
- Close · 2 min. Use the key afterward; check-day swaps use unrelated source rows. If unfinished at the time limit, record not yet observed and offer another short sitting; no completion-speed score.
