Rock Paper Scissors Baseball
Set up four objects in a baseball diamond configuration. Split your kids into two separate teams, lining both teams up at home base. When you say "go," the first player from each team begins walking heel to toe around the bases in opposite directions as quickly as possible. Wherever the two players meet, they face off with a quick game of rock-paper-scissors. The winning player continues walking around the bases, and the losing player runs home as quickly as possible. When the losing player reaches home, the next player on his team may start walking the bases to head off the progressing player. This continues until one team has made it all the way around the bases a set number of times.
