# C11 · After-own staff

## Complete neutral brief

4 pretend kits for a fictional class activity cost $7 each plus one $3 fee. Budget $40. 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

4 × $7 + $3 = $31; $9 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.
