Investigate how polygons can be joined and folded to form 3D shapes
Lesson details
Learning outcome
I can investigate how polygons can be joined and folded to form 3D shapes.
Key learning points
- 3D shapes can have flat faces. Each face is a 2D shape.
- 2D shapes can be folded and joined together to build 3D shapes.
Keywords
3D / three-dimensional - A shape with three measurable dimensions, e.g. width, height and depth.
2D / two-dimensional - A shape with only two measurable dimensions, e.g. width and length, but no thickness.
Face - The flat 2D surfaces of a 3D shape.
Common misconception
Children may apply the names of 2D shapes to 3D shapes (such as square and cube).
Have examples of the confused 2D and 3D shapes (such as square and cube) for the children to handle and explore. Discuss what is the same and what is different about them.
Teacher tip
Children would benefit from opportunities to explore how to join and fold 2D shapes to form different 3D shapes. This could be using construction materials as well as taking apart and building together different-shaped cardboard boxes and other packaging.

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.
