![]() ![]() Here’s what the National Curriculum expects to be taught about 2D shapes and 3D shapes, separated by year: 3D shapes in Year 1 Geometry is taught in every year group in KS1 and KS2.

A hexagonal prism has 8 faces, 18 edges and 12 vertices.A pentagonal prism has 7 faces, 15 edges and 10 vertices.A cuboid has 6 faces, 12 edges and 8 vertices.A cube has 6 faces, 12 edges and 8 vertices.A triangular prism has 5 faces, 9 edges and 6 vertices.A cylinder has 2 faces, 1 curved surface and 2 edges.A square-based pyramid has 5 faces, 8 edges and 5 vertices.A tetrahedron, or triangular-based pyramid, has 4 faces, 6 edges and 4 vertices.A cone has 1 face, 1 curved surface, 1 edge and 1 vertex. ![]() A hemisphere has 1 face, 1 curved surface and 1 edge.Tetrahedron or Triangular-based pyramidĪs well as the names, children need to know the properties of 3D shapes as listed below and in the printable table.Learning 3D shapes through Third Space Learning’s online interventions 3D shapes names A cone has one vertex, and a cube has 4 vertices. The singular of vertices is actually vertex which can be a bit confusing. Vertices are where two lines or edges meet in maths we refer to the corners of 3D shapes as vertices. What is an edge?Īn edge is where two line segments or faces meet. A sphere has 1 curved surface but no face. For example a square based prism has 5 faces. What is a face?Ī face is a flat surface to a 3D object. The properties of 3D shapes are their faces, edges and vertices which all have specific meanings in the context of primary school maths lessons. For example did you know that both a cube and a cuboid with a square base and straight sides are actually considered prisms. It’s worth knowing that geometrically prisms incorporate more solid shapes than you might traditionally think of as prisms. In primary school, your child will learn about the following key geometric shapes: spheres, cones, prisms and pyramids. This contrasts with 2D shapes where children must learn about both regular and irregular shapes. However, in the primary curriculum, children only need to know the names and understand the properties of the most common 3D shapes. Nearly everything we see and interact with in our day to day lives is a three-dimensional shape, from Lego bricks to sunflowers. Examples of 3D shapes are around us all the time.
