"The Post-It Note Club". Kids are divided into groups of 4-5 (same gender is best). Give them a bunch of Post-It note pads, and have them designate a person to be post-it(ed?). The goal is to cover the person entirely with post its in five minutes. The team who covers their person with the most post-its wins. (Any post-its that fall off do not count) The site has ideas for more games.
