Area of Rectangles, Triangles and Parallelograms (pptx)

Lesson objective:

To be able to find the area of triangles.

The lesson uses students pre-existing knowledge of areas of rectangles and parallelograms to workout how to find areas of triangles. Through a series of worked examples, students should realise that some triangles are either half a rectangle, or half a parallelogram, and hence gain a better understanding of how the formula for the area of a triangle works.

Includes; worked examples, practise questions, and a plenary.
