How to estimate the area under a curve using the trapezium rule.

As learning progresses, they interpret the area as displacement from a velocity-time graph.

**Differentiated Learning Objectives**

- All students should be able to use trapezia to estimate the area under a parabola within a given range.
- Most students should be able to estimate the area under the curve of a non-linear function with a given range.
- Some students should be able to interpret the area under the curve of a velocity-time graph as a measure of displacement.
