Teacher copy: This page may include teaching prompts or answer keys. Answer keys in this public library can be viewed by anyone. Give learners a clean prompt, use checks as formative evidence, and change a case locally when prior access matters.
Target/codes: independently reverse two unfamiliar four-beat phrase cards while preserving each phrase's internal marks; AC9AMUFD01, AC9AMUFC01. Prepare:M public check, M A4, broad cards; close the key.
Welcome · 3 min. Explain that the new paper music puzzle helps choose later teaching; there is no listening or performance demand.
Access · 4 min. Neutrally show starting C X X – X followed by D – X – – in two four-place groups. Read labels without moving either card.
Independent plan · 5 min. Child plans D then C while keeping all four internal positions in each phrase unchanged.
Child response · 7 min. Save the first full eight-place answer, where C and D now sit, and child's reason via cards, drawing, AAC, pointing or a neutral scribe.
Self-check · 4 min. Invite counting two groups of four and checking that neither phrase was remade. No corrective hint before first response is saved.
Close · 2 min. Open the separate key later; check-day swaps use different cards.
