It offers a good overview of some properties of shapes. All 3D shapes have faces (for example, the square parts on a cube, or the circle at the end of a cone), vertices (pointed corners) and edges (ridges where the faces meet). Different shapes have different numbers of these features (e.g. a cube has six square faces, eight vertices and twelve edges, a sphere has zero vertices, one face, and no edges.)
Engage with some of the games and videos on the website above and explore the features.
Please do not worry about being completely correct, the key objective is for your child to name the shapes and begin to talk about them using mathematical language.
