Target/codes: plan LOW LOW HIGH HIGH and name SAME at 1→2, UP at 2→3, SAME at 3→4; AC9AMUFD01, AC9AMUFC01. Prepare: A contour picture, Practice A, wide numbered strip and two fixed pitch rails.
- Welcome · 3 min. Revisit earlier LOW/HIGH labels, now across four places. Name HIGH as pitch, not volume or a physical height.
- Model · 4 min. Place two LOW dots then two HIGH dots. Trace three joins left to right: same level, up one level, same level.
- Try together · 5 min. Child chooses SAME/UP/SAME cards or uses a tactile two-rail guide. Four dots are four planned short tone events.
- Child choice · 7 min. Child chooses a plain contour or an invented paper lift scene and explains where the music plan rises. Optional candidate A cue (playback review held) only after local human review.
- Notice · 4 min. Save actual card order and child reason. A paper upward line does not show the child heard a higher tone.
- Close · 2 min. Keep the two pitch rails for a changing direction tomorrow.
