Understanding angles

How to tell they’ve got it

Tick these off as you see them — no test required.

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

Try this together

If you ask your child 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)?
