Why this why now

This unit is a summation of KS3 work on shape, but extends into parts of a circle and more complicated compound shapes.

Prior knowledge requirements

  • Identify and name standard 2D and 3D shapes
  • Calculate area, perimeter, and volume of standard shapes
  • Break down complex shapes into known components
