C12 · After-own staff

Complete neutral brief

5 pretend kits for a fictional community display cost $9 each plus one $4 fee. Budget $60. Find cost and amount left or over; all prices fictional.

Specific criterion

Model a repeated whole-dollar cost plus a one-off cost, calculate a total and interpret the amount left from a supplied budget.

One staff worked possibility

5 × $9 + $4 = $49; $11 left. Fee once.

Neutral support limit

Ask one neutral 'What does that amount count?' question if necessary and record it. Teach afterwards rather than covertly supplying the model.

Evidence scope

An individual response in a selected mode. Read/scribe if needed and record support; hide the teacher model first. Formative partial evidence, not an annual grade.
