The same 3D shapes can be composed from different 2D nets
Lesson details
Learning outcome
I can identify different 2D nets which will create the same 3D shape.
Key learning points
- A net is a 2D shape that can be folded and joined to create a 3D shape.
- There can be more than one way to create a net for a given 3D shape.
- Not all arrangements of shapes will form the net of a 3D shape.
Keywords
Net - A net is a 2D representation of the faces of a 3D shape, that can be folded up into the 3D object.
Common misconception
It is perfectly possible for pupils to be highly numerate but struggle with the spatial awareness needed to visualise / imagine whether a 2D net will fold together to form a 2D shape.
As part of the lesson design process you may wish to incorporate manipulatives such as construction materials for those pupils whose learning needs scaffolding. As with all scaffolding, aim to move pupils away from this when you can.
Teacher tip
If pupils are miscounting the faces of a 2D shape when planning to create its net, provide small sticky notes for them to place on a face when it has been counted.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
