1/2ST have been learning and revising 2D and 3D shapes and their dimensions.
Did you know that 2D shapes have 2 dimensions:
- sides and
And that 3D shapes have 3 dimensions:
- faces (the flat parts)
- edges (where two faces meet) and
- vertices (the 3D name for corners).
Today we played 2D and 3D shape bingo, where each student had a physical 2D or 3D shape. They also had 1 sheet each. Each sheet had 12 different boxes that listed the dimensions of a variety of 2D and 3D shapes. If you found someone who had the shape that matched the dimensions listed, then that person could sign their name.
Can you name and identify some 2D and 3D shapes around your home or workplace? Write to us to let us know what you have found!
