## Child direction

Can a repair drawer show what is left clearly? Pick one route. Show what the numbers mean, try a way, then check one result. You can stop after a useful part.

## Purpose

Subtract through regrouping or a connected count-up check.

## Complete fictional source

A fictional repair drawer starts with 806 labels. It uses 247 labels once. Find labels left.

## One own invitation

For 603 − 157, show what remains and a connected check.

## Access

Show, draw, type, sign, use your usual communication or direct an agreeing helper. Choose quiet/private work, switch a route, pause, pass or finish. One useful part is enough. A helper can read the exact words or scribe your choices; supplying an operation, count, regrouping or reason is mathematical help and is named. No speed, neatness, speech, handling or device requirement.
