# Home 29 · Make a useful proposal

**Try one tiny turn.**

Prepare: One familiar safe job described by the child, or MODEL capacity 700 mL and combined need 315 + 265 mL.

Invitation: Ask what we know, estimate, solve/compare, and decide what still needs a real reading before action.

Adult worked model/check: 315 + 265 = 580 mL;700 mL capacity is enough, with 120 mL difference in the model.

Choice and boundary: No required spending/travel/private information. Keep proposal and performed project separate.

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.
