Choosing measurement units
Choose and use appropriate standard units to measure length (m/cm), mass (kg/g), temperature (°C), and capacity (litres/ml) to the nearest appropriate unit
Lesson
Set out your lesson
Choose a sensible unit and distinguish reading a scale from making a measurement.
Before teaching
Can discuss the supplied example in an accessible mode; adapt directions without supplying the target answer.
Check the learner can follow the model with support before moving on. Source prerequisite ordering is not learner mastery; return to prerequisite work when needed.

Unit Conversions supports choosing and converting measurement units. Not every currency exchange problem.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.

Source, access and review notes
Public Illustrative Mathematics task page. The .html address responds HTTP 308 to this URL. An anonymous GET of this URL on 2026-11-12 returned HTTP 200 with no login or payment prompt. Where a teacher solution is present, it is on the same page as the student task; this check did not find a separate locked student view. An adult can use the student view section and should not read a solution aloud. Advertising was not observed in the fetched HTML text; that is not a browser, device, or ad-free guarantee. This is a paper or discussion task, not an automatically marked interactive game. Opening the link does not save practice or assess mastery. Diagrams on the page use missing or filename-only alt text, so they are not an accessible image equivalent. Accessibility still depends on an adult describing the picture.

“If you ask your child whether to measure a swimming pool or a piece of paper in cm or m, can they pick the sensible unit for each — and explain why?”
