Target/codes: translate the two-lane Practice B score into four summary symbols: upper only, lower only, together, quiet; AC9AMUFD01, AC9AMUFC01. Prepare: C column reader, Practice C.
- Welcome · 3 min. Show the stacked lanes and a second line of broad summary cards. They are two views of the same intended music, not two different scores.
- Model · 4 min. Read each vertical column: 1 upper only; 2 lower only; 3 both; 4 quiet. Put a matching outline icon beneath each column.
- Try together · 5 min. Child moves a four-column window and gives or chooses the summary sequence without needing speech.
- Child choice · 7 min. Child invents a replacement icon for one summary state, explains it, and tests whether a willing adult can read that icon; no personal data or image capture.
- Notice · 4 min. Record the two representations and actual adult feedback if received. Four summary cards do not demonstrate aural texture recognition or Mathematics achievement.
- Close · 2 min. Save the child's icon legend for later composition.
