Goal: state a question and source, build a one-image-per-response display, and make only supported comparisons. Proposed code: AC9MFST01. Prepare: Card 124; optional anonymous class choice with local consent, otherwise fictional motif Set C in Materials.
- Question · 3 min. Say the chosen question before any token is placed; name whether respondents are actual willing classmates or invented characters.
- Model · 4 min. Show one large icon token = one recorded choice; no name or private reason is attached.
- Guide · 5 min. Collect cards by the agreed private/fictional route and sort dot/stripe/star or local suitable categories.
- Independent display · 7 min. Child places each card once, compares any two groups by matching/counting and states exactly which displayed group has more or is equal.
- Boundary check · 4 min. Ask what the display cannot tell: why someone chose it, absent classmates' preferences or “everyone likes X.”
- Exit · 2 min. Child gives one bounded data sentence. If source is confused, label the dataset in large print and recheck a different set before fresh Day 125.
