Year 3 Right Angles in Shapes

This Year 3 Right Angles in Shapes lesson covers the prior learning of counting vertices on 2D shapes, before moving onto the main skill of recognising right angles within shapes.

The lesson starts with a prior learning worksheet to check pupils’ understanding. If they need more practice, you can choose other resources for that step. 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 Objectivexs
Mathematics Year 3: (3G4a) Recognise angles as a property of shape or a description of a turn
Mathematics Year 3: (3G4b) Identify right angles, recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn; identify whether angles are greater than or less than a right angle
