3D shapes and nets
Unfold a box to see its net.
Unfolding a box
Open out a cardboard box. You get a flat shape called a net. Folding the net makes the box again.
Prisms and pyramids
A prism has two matching ends joined by rectangles. A pyramid has a base and triangles meeting at a point. A cube is a special prism.
A net of a cube
A cube net has 6 squares. There are 11 different cube nets! Not every 6-square shape folds into a cube.
Faces, edges, vertices
Faces are flat surfaces. Edges are lines where faces meet. Vertices are corners. A triangular prism and a square pyramid both have 5 faces.
What I learnt
- I can describe prisms and pyramids.
- I can recognise nets of 3D shapes.
