Lesson details

Key learning points

  1. A right angle is a square corner.
  2. A right angle is a quarter turn.
  3. There are right angles in buildings and the environment.

Common misconception

Pupils may think there is only ever one right angle in an object or shape.

Provide opportunities for pupils to explore objects and shapes that have more than one right angle and show that these are not always rectangular e.g. some trapeziums can have more than one right angle.

Keywords

  • Right angle - A quarter of a full turn, a 'square corner'.

Take time to make a right angle checker with pupils, using split pins and paper or folding paper to make a right angle. This will support pupils in exploring their environment to identify right angles.
