S3.7.2 For the adult
Distance and time graphs
Can a picture show how a whole journey went?
What this chapter teaches
On a distance and time graph, a flat line means standing still and a steeper line means a faster speed. The learner draws a graph of a walk and finds the speed of each part.
Three questions to ask
There is no one right wording. Listen for the idea.
- What does a flat part of a distance and time graph tell you?
- Two walkers go 60 metres. One line is steeper. Who is faster, and why?
- How would you find the speed of one part of a graph?
After the chapter, the learner can
- Draw a distance and time graph for a journey
- Tell from a graph when an object is still, slow or fast
What they copy into their notebook
A distance and time graph has time across and distance from home up. A flat line is still. A steeper line is faster. A line going down is coming back home.
