Area and Perimeter

In this lesson, we will practise using the formulae to calculate the area of rectangles, parallelograms and triangles. We will model how to determine which measures within a diagram are appropriate to use for the formulae.

In this lesson, we will practise applying the formula to calculate the area of a trapezium. We will consider examples that use different trapezia in different orientations to help us determine what measures are suitable to use in our formula.

In this lesson, students will find the area of compound shapes by dividing the shape up into simpler more easily recognisable shapes and finding the sum of their parts.

In this lesson, students will find the perimeter of polygons and compound shapes by dividing the shape up into simpler more easily recognisable shapes and finding the sum of their perimeters.
