Snake in the Gutter
A group game that works well inside and out of schools is Snake in the Gutter. The game requires several kids, usually at least six or more. A pretend line must be created to serve as the gutter. At least three children should be designated "snakes." The snakes remain on one side of the line while the other children -- who are on the opposite side of the line -- try to cross without being tagged during the crossing. The game begins when someone announces "snake in the gutter."
Throw 'em Out
Some games not only come free of charge, but they help to teach children the positive benefits of teamwork. To play "Throw 'em Out," divide the children up into teams of two. The game also requires several foam balls as well as one blindfold per team.
One of the kids in each group wears a blindfold. The other partner is the "leader" who guides their partner using voice instructions; however, the leader is not allowed to touch or throw the foam balls. Once the blindfolded player finds a loose foam ball they throw it at the opposing team based on their partner's instructions. If a team gets hit with a ball, they are out.
Prisoner's Dilemma
Since the advent of the Internet, many great games have become available to anyone with a computer and an Internet service provider. "Prisoner's Dilemma" is a famous game theory conjecture of the 20th century.
One online game based on this conjecture is available at the Serendip website (see Resources). It requires you to compete against a computer inmate, choosing to compete or cooperate with them. You will get different amounts of coins based on their actions. If you compete, while they choose to cooperate, then you receive five coins and vice-versa. If you both cooperate, you get three coins. If you both compete, you each get one coin. The goal is to keep the coin average of return high.
Scavenger Hunts
Kids love scavenger hunts, and they can be a clever tool for having kids find gifts during a holiday, such as Easter. The rules are simple: a designated person hides objects, whether it be toys, candy or other random items. The children then go look for the items. To add an extra spin to the game, give each child a list of clues.
