Activities in this teaching pack include a worksheet to practise identifying the area of different irregular shapes by counting full and half squares and a set of cards to model how to measure the area of example shapes by using full and half squares.

The interactive presentation gets the children to explore how to identify the area of different irregular shapes by counting their matching number of full and half squares.

This lesson is part of a maths scheme of work to get the children to identify, record and compare the surface areas of a range of different rectilinear and irregular shapes by counting their matching numbers of squares. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
