Our U6 teams play a version of the game that is significantly modified from the  FIFA Laws of the Game.  The U6 teams play with fewer players (4 players on the field) and play on a smaller field (50 feet by 70 feet).  This allows developing players to have a much greater number of "touches" on the ball.  The rules for U6 play have significant changes that ensure that the young kids can get the most out of playing.
