Recognise angles as a property of shape or a description of a turn
What mastery looks like
- Identify angles at the corners of 2-D shapes
- Describe a turn (e.g. quarter turn, half turn) in terms of the angle made
- Explain that an angle measures the amount of turn between two lines meeting at a point
Check your understanding
If you ask Understanding angles to point to an angle on the corner of a book or door frame, can they find it — and explain that swinging a door open is also a kind of turn (angle)?
