Finding the area of a trapezium

Complete lesson on finding the area of a trapezium. Aimed at students in KS3-KS4 covering the topic for the first time.

Students should’ve already been shown how to find the area of a rectangle and parallelogram for this lesson to have the greatest impact.

The animated slideshow walks students through the process of finding the area of a trapezium using the ‘Two trapeziums make a rectangle/parallelogram’ method, building students up to discovering the formula (often by themselves).

The 25 slide lesson begins with key word definitions and builds up to reasoning and problem solving questions such as ‘Finding the side length given the area’ and ‘Compound shapes’.

Resource includes:

1. Keyword definitions
2. Mini ‘hands-on’ investigation manipulating trapeziums (with printouts)
3. Example questions to demonstrate in front of the class x 3
4. Walkthrough example questions supported by animated visual methods x 5
5. ‘We do’ whole class consolidation questions x 2
6. ‘You do’ independent practise question covering (applying, reasoning & problem solving x 5
7. Answers to the practise questions
