Line graphs
Construct and interpret line graphs for continuous data (e.g. temperature over time, plant growth); read intermediate values, identify trends, and solve comparison and difference problems
Lesson
Set out your lesson
“Line graphs means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- 20 counters
- Paper and pencil
Extra for the adult
Worked example. Start with 12 counters, remove 4, 8 remain. Write 12 − 4 = 8.
Optional challenge. For Line graphs, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Line graphs, not 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
- Read values from a line graph showing temperature over a day, including estimating between plotted points
- Construct a line graph from a table of continuous data, choosing an appropriate scale and labelling axes correctly
- Use a line graph to solve a two-step problem, such as finding the time period with the greatest rate of change
“If your child recorded the temperature outside every hour for a day, could they plot those readings on a line graph with proper labels — and then use it to answer questions like 'when was it warmest?' or 'how much did it drop between 3pm and 6pm?'”
