To each pair, you can add
with one person to be the observer. After one round, change roles.
Prepare two illustrations that are the same except for seven minor differences. For example, one shows a man with a moustache, in the other picture, that person does not have a moustache. One picture shows a bee above a flower. In the other picture, the flower is there without the bee.
Divide the group into pairs. Each pair sits back-to-back. Give each person in each pair a different of the picture. Each person is allowed to see only their own version. Each pair works together to discover the differences between their versions. They work on this by each one describing their picture to their partner.
