Exploring and investigating in maths is always more fun when you can use your hands and get creative.
We were finding out how many different nets we could make for various 3D shapes. We used different materials to make our nets.
It was also a good way to check the properties of the 3D shapes:
- We looked at the edges, where two faces meet
- We counted the vertexes, where the corners meet
- We counted the faces, the flat or curved surfaces
We even created some unusual shapes with many sides like the pentagonal dodecahedron
and the triangular pyramid prism,
Can you imagine what those two shapes look like?
