Having taught in primary schools for 40 years I still found your support a useful tool and a source of new and helpful information. You made my tutoring sessions a fun and successful way to learn. Many many thanks for being there for me.

A prism is a type of three-dimensional (3D) shape with flat sides. It has two ends that are the same shape and size (and look like a 2D shape). It has the same cross-section all along the shape from end to end; that means if you cut through it you would see the same 2D shape as on either end.

Apart from a cube and a cuboid, if you know the name of the polygon / 2D shape on the end of the prism it is easy to work out the name of the prism! (Triangle / triangular prism; Pentagon / Pentagonal prism, etc.)

Year 3 children will be taught to use modelling materials to make prisms and pyramids as well as nets for prisms and pyramids. Children could be given cardboard prisms and pyramids that they can unfold to see what a net looks like and might be asked what 2D shapes are needed to build the 3D prism or pyramid.

This is an excellent resource, for anybody looking to understand more about the curriculum that your children are studying and add some extra support at home. Highly recommended by a parent of two children who uses this from Reception to Year 4.

In each interactive tutorial, our digital teacher explains the method, shows you examples and then gives you a chance to practise what you've learned. Find out more.

If there is a specific area of learning your child needs support with, our packs offer information, advice and plenty of engaging practical activities. Written by teachers and experts and exclusively available to TheSchoolRun subscribers, learning packs (each 50+ pages long) are fun as well as practice-packed.

We often think of the famous pyramids in Egypt when the word ‘pyramid’ is mentioned. The Egyptian pyramids are square-based pyramids, but there are several other types of pyramids, each with a different polygon as its base.

A pyramid is also a three-dimensional (3D) shape. It has a polygon base and flat (triangular) sides that join at a common point (called the apex).

Year 2 children will be taught to name and identify prisms and pyramids in their learning of 3D shapes. They will learn to describe their properties for example the number of faces, edges and vertices. Children will be given colourful plastic models of 3D shapes to help them practise counting the number of faces, edges and vertices. They may be asked to complete tables to record their results.
