Drawing 3D Shapes

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.


Drawing 3D Shapes Lessons


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.

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.  Mathematics Teaching and Learning Folder All teachers receive a folder […]

Mathematics OFSTED Inspection – The Deep Dive

Earlier this week, my school took part in a trial OFSTED inspection as part of getting ready for the new inspection framework in September 2019. This involved three Lead Inspectors visiting our school over the course of two days. The first day involved a ‘deep dive’ by each of the Lead Inspectors into Mathematics, English […]

How to Solve Quadratics by Factorising

The method of how to solve quadratics by factorising is now part of the foundational knowledge students aiming for higher exam grades are expected to have.   Here is an example of such a question. Solve x2 + 7x – 18 = 0 In my experience of teaching and marking exam papers students often struggle with […]
