# C13 · After-own staff

## Complete neutral brief

4 pretend kits for a fictional class activity cost $19 each plus one $2 fee; budget $80. Round both prices up to whole tens, explain the check's limits and calculate exactly.

## Specific criterion

Choose and explain rounding or bounds, then recognise when an exact calculation is needed near a budget limit.

## One staff worked possibility

Upper check $90 above the budget does not alone prove an overrun. Exact $78, $2 left.

## 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.
