Target/codes: use two role symbols to assign first T and then T′ while keeping their marks and sequence; AC9AMUFD01, AC9AMUFC01. Prepare: C turn arrow, Practice C, large circle/triangle cards.
- Welcome · 3 min. Offer circle and triangle as non-personal role symbols. These are score labels, not required classmates or instruments.
- Model · 4 min. Place circle above T and triangle above T′, with one thick arrow crossing the phrase divider. The arrow means planned “first, then,” not a measured speed or forced turn.
- Try together · 5 min. Child points from role 1 to role 2, keeping T = X REST X REST and T′ = X REST REST REST intact.
- Child choice · 7 min. Child directs role cards for a two-window gallery or plain score. If people or sound are later involved, ask each person and choose comfortable safe sources; a paper plan is enough today.
- Notice · 4 min. Record the child's role allocation and score order. Never infer that two people actually took turns from the arrow alone.
- Close · 2 min. Save the hand-off score and invite comparison with another possible answer.
