Division by three yes no game powerpoint

Simple PowerPoint (with 50 slides) asking whether numbers are divisible by three or not. Each time annimation then says "Yes" or "No".

Use it after teaching it as a plenary or as a discussion as a starter.

Pupils can write their answers (and then show the correction) on individual pupil whiteboards - either on own, in pairs or in tables of four.
Pupils can use red, green, yellow (for don't know) cards to show their answer. For extra fun you can have them point "Usain Bolt Style" to the left or right of the room for their answer. For complete chaos you can have them run to the left of the right of the classroom for yes or no.

The important thing is to get pupils to explain their answers to help everyone's understanding.

You can quite easily and quickly add many more questions by simply duplicating a yes or no slide and adding in your changes.

I would usually back this exercise up with a worksheet or textbook exercise which they can do independently afterwards.

You can extend this by getting the pupils to make up their own slides (on their whiteboards) to test other pupils.
