Area and Perimeter

This resource, aimed at early years and lower primary, contains a collection of dynamic and interactive spreadsheets designed to illustrate teaching points on the topics of area and perimeter. Ideal for use with the whole class at the start or end of a lesson it provides screens on the following:

Pinboard draw squares, rectangles and other shapes to discuss area and perimeter; can also be used to generate random squares and rectangles.

Halve the board halve the area of a board in as many different ways as possible.

Estimating area generate asymmetric shapes and discuss ways to find their area.

What’s missing? a chart shows length, width, perimeter and area of a range of squares and rectangles, but some of the values are missing.

Square units a square is used to illustrate the relationship between Km.

Circle Area estimate the area of different circles and find patterns in the answers.

Rectangular shapes calculate perimeter and area of different L- shapes and symmetrical letters of the alphabet.

Triangles find the area of a variety of triangles by subtracting the area of the circumscribing rectangle.

This resource has been provided by the Virtual Textbook. It is part of the Geometry and Measure sub-collection, which contains many further curriculum linked interactive spreadsheets.
