Why this why now

This unit builds upon the preceding unit on shape and develops fluency of understanding of angles.

Prior knowledge requirements

  • Identify types of angles (acute, obtuse, right, reflex)
  • Understand angle facts (e.g. angles on a line, around a point)
  • Use a protractor to measure and draw angles

Why this why now

This unit builds upon the preceding unit on shape and develops fluency of understanding of angles.

Prior knowledge requirements

  • Identify types of angles (acute, obtuse, right, reflex)
  • Understand angle facts (e.g. angles on a line, around a point)
  • Use a protractor to measure and draw angles

Angles

In this unit pupils use their knowledge of corresponding, alternate and co-interior angles to reason through and solve more complicated problems.
