2D Shapes Carroll Diagrams

This resource is designed to develop an understanding of the sorting of 2D shapes on a Carroll diagram using particular properties as criteria. Shapes are sorted by two varying criteria.

Each of the four levels of difficulty can help children to identify and know the names of 2D shapes of different colours, sizes and orientations. Levels 3 and 4 support the understanding of the properties of regular and irregular 2D shapes, and right angles.

N.B. Squares are classed as rectangles in this game. Too often children are taught to categorise rectangles and squares differently when they should be learning that squares are really 'square rectangles'. This is recognised in the National Curriculum for England in Year 1 Statutory requirements.
