- Welcome · 3 min. Revisit two matching T cards and ask where a response can differ while the first phrase stays.
- Model · 4 min. Replace only the second phrase's local count 3 X with REST. Trace unchanged counts 1, 2 and 4 in both cards; phrase 2 has one event, not two.
- Try together · 5 min. Child names the only changed cell and shows eight beat places, two events in call, one in answer.
- Child choice · 7 min. Child makes the one-mark change in a paper garden, puzzle-station or neutral score and states an intended quieter or shorter musical plan, with no claim about a listener's feeling.
- Notice · 4 min. Save first attempt, changed location and explanation. Optional actual sound, if chosen, is observed separately.
- Close · 2 min. Put the two wide cards in call-then-answer order for a safe hand-off plan.
