How it works
Count the sides and corners to name a flat shape: 3 triangle, 4 quadrilateral, 5 pentagon, 6 hexagon.
Solid shapes have faces. A cube has 6.
A shape stays the same shape when you turn it.
Worked examples
Count the sides
- A shape has 5 straight sides.
- Touch each side as you count: 1, 2, 3, 4, 5.
- A shape with 5 sides is a pentagon.
A turned shape
- A triangle is turned on its side.
- Count the sides: 3.
- Turning does not change a shape. It is still a triangle.
Faces of a solid
- A cube is a solid shape. Its flat sides are called faces.
- There is a top, a bottom and 4 around the sides: 1 + 1 + 4 = 6.
- A cube has 6 faces.
