# Home 24 · Enough room in a container

**Try one tiny turn.**

Prepare: Labelled model capacities 300 mL and 650 mL, or familiar adult-reviewed unbreakable empty containers.

Invitation: Choose a container for a 450 mL target. Explain why its label helps more than its height.

Adult worked model/check: 650 mL fits 450 mL;300 mL is 150 mL short.

Choice and boundary: No pouring, drinking or purchase needed. Actual water work needs adult review.

Usual communication, exact scribing, private/untimed work and stopping are welcome. Keep a model answer separate from your child's own attempt; do not correct it silently. Observe one useful reason and choose a new unrelated example if wanted.
