How can you tell they’ve got it: Right Angles & Turns?

If they’ve got it, you’ll see things like: Use a right-angle checker to identify right angles in shapes and the environment; Classify angles as right angles, less than a right angle, or greater than a right angle; Explain that 4 right angles make a full turn (360°). Or just try it together: If your child looks at the corner of a piece of paper, can they tell you that's a right angle — and that spinning all the way round takes four right angles?

Right Angles & Turns

Your child can spot right angles, like the corner of a page. They know four right angles make a full turn.

In curriculum terms

Identify right angles; recognise that two right angles make a half-turn, three make three-quarters, and four make a complete turn
