Beach Ball Race- kids work together to hold beach ball between their backs for the first leg of the race, then their sides, then elbows. The field Day Challenge is halfway down on web site includes water relay, tricycle race, and tug-of-war.
Candy Medals - so fun for a special kids game night to award the winners. But kids aren't the only ones who like candy, so it ought to work with teachers during PD. Think I'll give this idea a try and maybe I'll use something other than candy.
