Now make two right angles using the two sticks.
Can you make three right angles? Four right angles?

Why do this problem?

This problem will help children identify right angles and multiple right angles in their environment.

Key questions

Can you see any right angles in the room?
How do we know that's a right angle?
Have you tried moving this lolly stick?

Possible extension

For a tricky challenge, some children could try Take the Right Angle which asks them to find times when the hands on a clock make a right angle.

Possible support

It might help just to move the sticks around over each other to get some ideas. Learners  could use lolly sticks or headless matches if  they are not using the interactivity.
