Y4
Year 4 Triangles
This Year 4 Triangles lesson covers the prior learning of recognising and describing 2D shapes, before moving onto the main skill of recognising and clasifying types of triangle.
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.
