Year 5 Lengths and Angles in Shapes

This Year 5 Lengths and Angles in Shapes lesson covers the prior learning of quadrilaterals and triangles, before moving onto the main skill of lengths and angles in shapes.

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

 

National Curriculum Objective
Mathematics Year 5: (5G2a) Use the properties of rectangles to deduce related facts and find missing lengths and angles
Mathematics Year 5: (5G4b) Identify: angles at a point and one whole turn (total 360), angles at a point on a straight line and ½ a turn (total 180) other multiples of 90°

Due to the nature of the questions on the worksheets, this lesson is not available in interactive format.
