Welcome · 3 min. Read the section names; the middle can wait while we check the final pair.
Model · 4 min. Place opening L H at 1–2. Copy L H, not H L, into 5–6. Match first-to-first and second-to-second with broad pairing lines.
Try together · 5 min. Child compares two fixed tactile or printed pairs and repairs one adult-made order error on a separate example.
Child choice · 7 min. Child invents an opening H L, L L, H H or another permitted two-event key, then directs an exact final copy for a toy train's return or plain score.
Notice · 4 min. Save first pair, final pair and whether child directed order. A copied opening is only a form plan until made/heard.
Close · 2 min. Tomorrow a contrasting middle makes the return matter.
