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.

Last year my school had a OFSTED trial inspection. Whilst the maths team recieved favourable feedback the inspectors noted a need for a focus on whole school literacy. Because of this I was asked to demonstrate how we develop student’s literacy in mathematics. Literacy in Mathematics By developing student’s literacy in mathematics we aim to […]

There are two key learning points when solving problems with angles in polygons. The first is to understand why all the exterior angles of a polygon have a sum of 360°. The second is to understand the interior and exterior angles appear on the same straight line. Students can be told these two facts and […]

When getting ready for a new school year I have a list of priorities to work through. Knowing my team have all the information and resources they need to teach their students gives me confidence we will start the term in the best possible way.
