3D shapes teaches students how to draw them using isometric and elevation drawings. Students progress onto constructing nets of a range of solids. This is a key topic before moving onto finding the volume and surface area of cubes and prisms in Year 10 Term 4 for the Higher GCSE course.

**Prerequisite Knowledge**

- draw 2-D shapes and make 3-D shapes using modelling materials; recognise 3-D shapes in different orientations and describe them
- compare and classify geometric shapes, including quadrilaterals and triangles, based on their properties and sizes

**Success Criteria**

- identify properties of the faces, surfaces, edges and vertices of: cubes, cuboids, prisms, cylinders, pyramids, cones and spheres
- construct and interpret plans and elevations of 3D shapes.

**Key Concepts**

- Students need to understand the geometrical difference between a prism and pyramid.
- Horizontal lines are not drawn on isometric paper.
- Students need to sketch a solid from elevation drawings and vice-a-versa

**Common Misconceptions**

- Students often get confused which elevation to draw and how to include hidden detail.
- Some students find it difficult to draw 3D shapes on isometric paper. Encourage the use of multilink cubes to aid drawings.
