Grab & Tag
If you're looking for a fun outdoor game for two kids to play, set up two bases about 40 feet apart for a quick game of grab and tag. Have the kids each start on a base and place a ball between them in the grass or sand. When you say "go," each player runs toward the ball, grabbing it and running back to his own base, or chasing the player with the ball, trying to tag him before he makes it home. The player who successfully makes it home or tags his opponent wins a point. The first player to five wins the game.
