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.
Source review is complete for this two-week edition. Local suitability and classroom use still need review. Earlier candidate or pending-review words are retained in the original files; full-year coverage, translations and audio are not claimed.
Keep these complete conditions with PDF, SVG, text and ZIP copies. PDFs retain their full attached source and notice files; the downloadable packets keep their declared companions.
