Two boys on one each and two girls on the other two chairs. There is also a blank space left in the circle. I usually mark this spot with an old cushion. Everybody writes their name on a piece of paper and puts it into a container. When everyone's name is in the container someone takes the container around and children select a name but without telling anyone else the name on the piece of paper they have picked.
Children are no longer their given name they are now the name on the piece of paper.
The object of the game is to get all of your gender on the four seats. The person sitting on the right of cushion calls out a name. The person with that name on their piece of paper moves and sits where the cushion is. The person who is on the right of the new empty space calls out a name and they move to the empty space and so on until all of the one gender is on the four seats. Children cannot call out their given name, they cannot say the name that the person is who has just moved.
