Bar graphs
Interpret and present discrete and continuous data using appropriate graphical methods, including bar charts and time graphs
Lesson
Set out your lesson
Choose category bars or a time graph and read the axes.
Before teaching
Use this short check, then start teaching.
Inferred, not a taxonomy edge: learner can access the supplied prompt with agreed support and can explain or mark a response. If earlier skills are unfamiliar, use the prerequisite topic for teaching; an authored prerequisite is not proof this learner is ready.

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
- Read a time graph showing temperature changes over a day
- Present data about plant growth over weeks as a time graph
- Explain the difference between a bar chart (discrete) and a time graph (continuous)
“Can your child choose the right type of chart for some data — for example, a bar chart for favourite colours or a line graph for temperature over a week — and draw it correctly?”
