Measuring & Plotting Lengths
Generate measurement data by measuring lengths to the nearest whole unit and display the data on a line plot
Lesson
Set out your lesson
Practise the bounded task in Measuring & Plotting Lengths; see exact limits before inferring broader coverage.
Before teaching
Use this short check, then start teaching.
Can read a centimetre ruler; measurements must be actual if described as observed.
Exact directed source edges retained; earlier authorship is not learner attainment.

The Longest Walk
Before you open · source notes
The longest walk supports measuring and plotting lengths. Not every volume measure.
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 compare two walked lengths and say which is longer.
Opening this link does not save learning or assess mastery.
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.

Check understanding
- Measure the lengths of several objects and record the data
- Create a line plot with a horizontal scale marked in whole-number units
- Interpret a line plot to answer questions about the data
“If your child measures the length of ten leaves to the nearest cm and records the results, can they display the data on a simple number-line plot — grouping leaves of the same length?”
