Target/code: identify and continue a three-position repeating unit rather than only predicting its first next card; AC9MFA01. Prepare: P178 CIRCLE, CIRCLE, SQUARE repeated twice, three blanks and repeat mat.
- Notice · 3 min. Show the six cards; ask what repeats in the same order. Some children may see “two circles then a square”; accept pointing as well as words.
- Model · 4 min. Box the first CIRCLE–CIRCLE–SQUARE and match it to the second full three-card part.
- Guide · 5 min. Child copies the strip and marks the boundary between two units, using large cards or adult-directed placement.
- Independent route · 7 min. Day 178 A/B/C in a toy border, fictional flag mark or gallery label requires the whole three-card unit and next three cards.
- Evidence check · 4 min. Offer a proposed continuation CIRCLE–SQUARE–CIRCLE. Ask child to compare all three places and repair the wrong order.
- Exit · 2 min. Child shows where the unit begins again. If only the next circle is known, box the first whole unit and copy a fresh one later.
