Review understanding and identification of right angles
I can recall understanding and identification of right angles.
Lesson details
Key learning points
- A right angle is a square corner.
- A right angle is a quarter turn.
- There are right angles in buildings and the environment.
Common misconception
Right angles are only where a horizontal and vertical line meet to create a square corner.
Ensure pupils are shown a wide range of right angles in a variety of orientations and contexts so that pupils can better generalise the features of a right angle.
Keywords
Right angle - A right angle is a quarter of a full turn. It can be known as a ‘square corner’.
You can use different angle tools to measure either the inside of a right angle (folded paper) or the outside of a right angle (angle strips). Ensure pupils are familiar with using both tools to find right angles in their own settings.
