Measuring length (age 6+)
Measure the length of an object using same-size length units laid end to end with no gaps or overlaps
Lesson
Set out your lesson
Measure with equal units touching end to end.
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.

Before you open · source notes
Measure body lengths with same-size units laid end to end. Emphasise no gaps or overlaps; this is not a standard-ruler certification.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.
Before you openAsk how many units spanned the length and whether gaps or overlaps appeared.

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 2026-11-11 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 book by laying paper clips end to end and counting them
- Understand that the length measurement is the number of units that span the object
- Avoid gaps and overlaps when placing units
“If your child is measuring the length of a table using identical toy bricks, can they lay them end to end with no gaps — and tell you how many bricks long the table is?”
