Arrange the chairs in a circle, facing the middle. All the children sit down.
An adult stands outside the circle and calls out "A great wind blows for everyone who....", fills in the blank with a statement that will affect some of the group (see ideas below). Anyone who is affected must stand up and find another chair which is at least 2 chairs away from their own.
If a large group of children stand up, the adult should quickly remove one of the chairs from the circle as soon as the kids stand up and begin moving. Any child who cannot find a chair moves outside the circle and helps the adult come up with ideas for the next "great wind blows".
Here are some ideas:
A great wind blows for everyone who has a little brother
A great wind blows for everyone who has a big sister
A great wind blows for everyone who has been to France
