Area of 2-D shapes

In this lesson, we will use different units of length to describe perimeter; calculate the perimeter of polygons and estimate the perimeter of 'curved' shapes.

Describing perimeters

In this lesson, we will use different square units to describe area and use informal counting strategies to calculate area.

Describing areas

In this lesson, we will analyse the effect of cutting, moving and combining shapes on area and perimeter.

Cutting and combining shapes

In this lesson, we will explore the perimeter and area of rectangles as the dimensions change.

Exploring rectangles

In this lesson, we will learn to calculate the area (and perimeter) of rectilinear shapes by 'combining' rectangles.

Rectilinear shapes

In this lesson, we will learn to calculate the area of parallelograms by rearranging rectangles and we will arrive at a formula for the area of a parallelogram.

Area of parallelograms

In this lesson, we will learn to calculate the area of triangles and link the area of triangles to the area of parallelograms.

Area of triangles

In this lesson, we will solve further problems involving area of triangles.
