# Properties of Shapes

In Year One, children can recognise and name solids and 2D shapes. They are able to use this knowledge to see how groups have been sorted and to make patterns.

When in Year Two, children are able to describe the 2D shapes learnt in Year One in terms of sides and vertices. They are also able to recognise lines of symmetry. Children can also describe 3D shapes in terms of vertices, faces and edges.

In Year Three, children begin to describe shapes in terms of the types of lines and angles they have. They can recognise acute, obtuse and right angles as well as parallel, perpendicular, horizontal and vertical lines.

During Year Four, children revisit angles by comparing them and identifying the smallest/largest angel in a shape. This to help them check their measuring of angles in Year Five. They also return to symmetry, completing shapes to make them symmetrical and identifying shapes with lines of symmetry.

Children in Year Five learn how to find missing angles by using facts about angles on a straight line and around a points. They also learn how to use a protractor to measure angles and can check their measurements by using their knowledge of acute, obtuse and right angles learnt previously.

In Year Six, children learn about the different parts of a circle and how they relate to each other. They consolidate their knowledge of 3D shapes and explore the pattern in the total of the angles in polygons. They look again at the size of angles on straight lines and around a point, creating equations to help them remember this. Children continue practising how to use a protractor to measure angles as well as finding missing angles in triangles and quadrilaterals.
