Y6 Maths
Year 6 Angles in Polygons
This Year 6 Angles in Polygons lesson covers the prior learning of identifying regular and irregular polygons, calculating missing angles in a triangle and calculating missing angles in a quadrilateral before moving onto the main skill of understanding interior angles in 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 6 (6G2a) Compare and classify geometric shapes based on their properties and sizes
Mathematics Year 6: (6G4a) Find unknown angles in any triangles, quadrilaterals and regular polygons
Mathematics Year 6: (6G4b) Recognise angles where they meet at a point, are on a straight line, or are vertically opposite, and find missing angles
