Measuring with different units
Measure the length of an object using two different length units and describe how the measurements relate to the size of the unit chosen
Lesson
Set out your lesson
Explain why measuring the same length with a smaller unit gives a larger count.
Before teaching
Ask for an example of one prerequisite idea; revisit if needed. Historical graph coverage does not establish this learner’s readiness.

Converting fractions of a unit supports measuring with different units. Not every customary-only table.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.
Before you openAsk the learner to rewrite a fractional measurement in a smaller unit.

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.

Check understanding
- Measure a desk in both centimetres and inches and compare the two numbers
- Explain that measuring with a smaller unit gives a larger number
- Predict whether a measurement in centimetres will be greater or less than in inches
“If your child measures the same book in centimetres and then in inches, can they explain why the numbers are different even though the book hasn't changed size?”
