We present this activity as a way for adults to engage with just a few pupils at a time. It works well to encourage the youngsters to talk about their thoughts and how they have reached their conclusion/s.

There are a lot of variations but the open questions allow the children to speak freely. Please watch this very short video as a stimulus for what you could do with your own pupils. However, it would be worth reading the Notes first.
