What you need to know
You need to:
name 2-D shapes
count the number of sides and vertices
find vertical lines of symmetry
compare and sort common 2-D shapes and everyday objects
name 3-D shapes
count the number of faces, edges and vertices on a 3-D shape
compare and sort common 3-D shapes
find the 2-D shapes on the 3-D shapes.
- Some examples of 2-D shapes:
circle
triangle
square
pentagon
hexagon
octagon
- A line of symmetry is an imaginary line where you could fold the shape and the two sides are exactly the same.
- Some examples of 3-D shapes:
cube
