Properties of 2D and 3D shapes and angle

Finding out what congruent shapes are, how to recognise a scalene triangle and using Venn diagrams and tree diagrams to classify shapes.

Looking at the properties of cuboids, prisms and pyramids.

Nets of cubes and pyramids and making 3D shapes from cubes. Using a pinboard to make 2D shapes that obey set rules.

More nets of 3D shapes which can be cut out and folded to make the shapes.

Net of a 12 sided shape, more on nets for a cube and some ideas for tangrams.
