# Calculate Perimeter Lesson

This Year 3 Calculate Perimeter lesson covers the prior learning of measuring the perimeter of simple 2D shapes, before moving onto the main skill of calculating the perimeter.

The lesson starts with a prior learning worksheet to check pupils’ understanding. If they need more practice, you can choose other resources for the step here. 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.
