Goal: independently transfer layered-pay and percentage-base reasoning to the new festival/print prompt. 25 = 2 + 3 + 12 + 5 + 3.
- 0–2: Name the check public, fresh relative to cards and not a secure examination or QCAA instrument. Explain first work will be kept before feedback.
- 2–5: Give the exact prompt and neutral access supports without modelling its numbers.
- 5–17: Routes: arrange labelled regular/additional/allowance and cost/price strips; complete blank two-base tables; type, write, dictate or AAC the same calculations and reasons. Keep the first independent response and note any mathematical hint.
- 17–22: After collection, ask “which count meets which rate?” and “which denominator names mark-up or margin?” Use a different invented example, never erase first evidence.
- 22–25: Consult the public worked key to choose one response move. Move: if a learner already saw answers, use a new local parallel check.
Alternative domains: fictional convention booth or sports-event crew only after first collection. Optional/home: explain why a fixed allowance and hourly rate use different units. Two after-check swaps.
