Frogs and Ants
I learned this game at the 2005 OCA Conference, at the "No Equipment, No Planning Time, No Problem" session facilitated by Matt Barr.
This is a large group tag game. In a group of 30 or so, assign 5 frogs to be "IT" and the rest of the players are ants. Designate the playing area, including a safe zone (the ant colony). Start the game by having the ants run around the playing area. The object of the game is for the frogs to touch the ants. Once an ant is touched, it must lay on its back with both arms and both legs in the air. This cry for help signals FOUR ants to rescue their fellow ant. A rescue is successful if four ants (all arriving at the same time) can carry their fellow ant to the safety of the colony where it is reborn to play again. The four rescue ants must arrive at the injured ant at the same time and start working or risk being touched by a frog and becoming injured ants themselves. If there are four ants attached and working at the same time, they cannot be touched by a frog. The working ants must transport the injured ant to the safe area (colony) where all can then rejoin the game in progress.
