Year 5 Regular and Irregular Polygons
This Year 5 Regular and Irregular Polygons lesson covers the prior learning of describing and drawing 2D shapes, before moving onto the main skill of recognising and distinguishing between regular and irregular polygons.
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.
National Curriculum Objective
Mathematics Year 5: (5G2b) Distinguish between regular and irregular polygons based on reasoning about equal sides and angles
Due to the nature of the questions on the worksheet, the Extension worksheet is not available in interactive format.
