Name Wave
I learned this game when I did my "Tribes" training with the York Region District School Board.
Everyone stands in a circle. The leader of the group introduces herself to the group by saying her name, and doing an action (anything she likes) along with it. For example, I might say "Becky" while saluting at the same time. Starting with the person immediately to the leader's right, everyone repeats the leader's name with the appropriate action. The effect is that of a 'wave' of "Becky's" and salutes traveling around the circle. Once the leader's name/action have made it all the way around the circle, then the person standing immediately to the leader's right will say her name and show the group her action. The new name/action are repeated all the way around the circle. Repeat this process until everyone's name has been introduced.
