To properly play a game, whether football, badminton or even Monopoly, people first have to learn the rules. By understanding where to be, what to do and what to expect during the course of play, players can avoid accidental collisions and injuries. Then, once they're out on the field, kids should pay attention to what's going on around them. They should especially listen to coaches and teammates -- they're the extra eyes and ears to keep other teammates where they ought to be. Not only will that reduce the chance of getting hurt or hurting someone else, kids will also play better.
