# Perimeter of Rectilinear Shapes Lesson

This Year 4 Perimeter of Rectilinear Shapes lesson covers the prior learning of drawing 2D shapes and adding and subtracting lengths, before moving onto the main skill of calculating the perimeter of rectilinear shapes.

The lesson starts with a prior learning worksheet to check pupils’ understanding. The interactive lesson slides recap the prior learning before moving on to the main skill. Children can then practise further by completing the activities and can extend their learning by completing an engaging extension task.
