 Read and use the terms ‘vertex’ and ‘vertices’
 Recognise 3-D shapes and make collections, for example, of shapes that are prisms.
 Know that a prism has the same cross-section along its length, and that its two end-faces are
identical.

triangular faces at opposite ends and the other three faces are rectangles'; 'A hemisphere is a
sphere cut in half. It has one flat face and a curved surface.'
 Sort 3-D shapes using criteria such as the number of vertices, edges or faces . They find the
number of edges of assorted prisms to investigate the general statement : The number of
edges of a prism is always a multiple of 3.
 Sort 3-D shapes in different ways according to properties such as:
-Whether or not they are prisms
-The number of faces, edges, vertices
 To draw a picture of a cube, would you use straight or curved lines? What about a cylinder?

no right angles;
all sides equal;
five vertices.

 Recognise that two or more shapes can be put together
in different ways to make new shapes. For example, find
different shapes that can be made by fitting four cubes
together face to face.
