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: compose from an unfamiliar brief: four places, A at 1–3 and one B at the end, then name the single source change and intention; AC9AMUFD01, AC9AMUFC01. Prepare:public V, V A4, blank A/B source cards; key closed.
Welcome · 3 min. This paper composition puzzle helps plan next teaching and does not demand sound.
Access · 4 min. State the new brief exactly: first three events keep A; final event uses B once. Show blank four-place source strip and A/B legend, not a completed row.
Independent plan · 5 min. Child selects one source per place and considers the three gaps.
Child response · 7 min. Save first full four-card score, the source-change boundary and a child-stated musical intention by cards, AAC, pointing, drawing or neutral scribe.
Self-check · 4 min. Child checks all four places against the written brief without answer cues.
Close · 2 min. Consult separate key later. This score is not proof that B was heard, played or shared.
