Start with multiple squares of different sizes and remove squares, forcing your group out of "cliques" and into the final large square.

Ask group members to enter any square with whomever they feel most comfortable. Ask them to take a look around and see if it is surprising to see with whom they ended up.

Next, ask them to exit and remove the first square. Continue until there is only one square and everyone is in it. You may also choose to facilitate the two sections of this activity independently.
