interpret line graphs representing change over time; discuss the relationships that are represented and conclusions that can be made
Students construct line graphs for ordered data, read interpolation and trends cautiously, and recognise how a broken or truncated vertical scale changes visual impact without changing the data.
A line graph connects values in an ordered variable; its axis scale controls how differences appear and must be read before interpreting trend.
Plot time on the horizontal axis, temperature on the vertical axis and connect points because values are ordered through time.
A discontinuous scale can reveal detail but can also exaggerate differences. Quote numerical change and inspect axis intervals.
Learning routine: Represent → Reason → Calculate → Interpret → Verify
Plot time on the horizontal axis, temperature on the vertical axis and connect points because values are ordered through time.
A discontinuous scale can reveal detail but can also exaggerate differences. Quote numerical change and inspect axis intervals.
Now transfer the same relationship to a new situation and justify the result with precise vocabulary.
Content description: interpret line graphs representing change over time; discuss the relationships that are represented and conclusions that can be made.
Build or represent line graphs and discontinuous scales and label the features, coordinates, data or outcomes.
Use a second representation or method and explain what each makes easier to see.
Apply the concept to a new design, data set or chance situation and verify every condition.
Core idea: A line graph connects values in an ordered variable; its axis scale controls how differences appear and must be read before interpreting trend.

Open Classroom ViewThe SkillrHub lesson remains the primary learning resource. This optional video reinforces the explanation; you can complete the lesson and practice without watching.
Before you watch:
Khan Academy — Read a graph showing how a quantity changes over time.
As you watch: How do you tell when a quantity stays the same, rises or falls?
Load video player Loads YouTube in this lesson. See the video notice below.
Try it: Make a five-day temperature line graph from sample data and explain the interval with the greatest change.
