Target/codes: copy all four decisions two shared beats later; partial AC9AMUFD01/FC01. Prepare: copy-later, own idea, aligned rows/local mapping; invitation C.
- Welcome · 3 min. “Same idea. Start B after two waits.” Child chooses exact graphic/raised/word/direct-adult access.
- Model · 4 min. A local 1,4 at shared 1,4 becomes B local 1,4 at shared 3,6. Compare A 1→B 1, A 2→B 2, A 3→B 3, A 4→B 4 including waits. Different source identity is allowed.
- Try together · 5 min. Adult copies one wait incorrectly; child finds/restores corresponding decision later. No count-only check; remove worked example before own piece.
- Child choice · 7 min. Child builds a complete delayed B copy of own A, keeps two initial B waits/A done 5–6, then reads or rehearses B alone first. Optional combined reviewed making only if wanted; direct two adults/silent readers valid.
- Notice · 4 min. Save exact four correspondences. Same event count alone insufficient. Windows overlap even if marks never coincide; no-sound copy is composition, not actual performance.
- Close · 2 min. Child chooses a favourite shared place or stop. No learner labelled fast/slow/first/second in rank.
