Investigate how polygons can be joined and folded to form 3D shapes
I can investigate how polygons can be joined and folded to form 3D shapes.
Lesson details
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.
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.
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.
