Goal: describe D's three-shape repeating part in an order another person can follow. Proposed codes: AC9EFLA07, AC9EFLY05, AC9EFLY10. Prepare: D patterned source, broad tactile tiles or linear transcript, Card 176.
- Oral/print · 3 min. Say circle circle square with one broad word/shape token per spoken word; child identifies the three-part phrase, not a letter task.
- See/hear · 4 min. Show or read D's six tiles without naming the repeating unit. Ask what might come next and label it a prediction.
- Model · 5 min. Bracket first circle/circle/square, then the same three again. Explain why a description “two circles, then a square, repeat” is clearer than “some shapes”.
- Child try · 7 min. Choose train-window, book-border or paper-garden sign route; child uses paper tokens, point, AAC or adult-directed placement to tell the repeating part and next three positions.
- Check · 4 min. Offer circle/square/square as a distractor. Child compares exact order with D; record the first explanation, not speed of copying.
- Exit · 2 min. Ask how someone using text or touch could know the sequence without colour.
