(Conyers, Ga, U.S.)
This is a good game to play with larger crowds, that are even numbered. This game may SOUND boring but after a few rounds the kids are jumping up and down and screaming numbers at each other. Its fun for both the kids and the adults watching them.
You get all the kids to pair up with someone of the same gender. They turn back to back.
Then you have someone stand up in front of the room(this can be a "left over" child if you have an odd number). Then the kids randomly put up a number of fingers. When the person in the front of the room shouts "GO!" The kids turn around and count their partners fingers. Who ever counts first and calls it out is the winner and they move on to find a new partner.
