Measurements from real-life situations give different shapes of graph.
Using the cards, match each scenario with its graph.

When interpreting a graph, which key features are useful?
At the end of the activity
Describe a real situation that would give a linear graph.
Describe a real situation that would give a curved graph.
Describe a real situation that would give a graph with more than one section (straight or curved).
