These are the regular rules of soccer. There may be some variations for younger age groups. Besides understanding the topics below, it is important to become familiar with the Short-sided guidelines for ages 5-12.
11 players (1
goalkeeper and 10 field players)
A game must be
cancelled if there are less than 7 players on any team.
There are four main positions:
In AYSO, each game is split into four (4) quarters to guarantee that each player gets to play at least one half of the game. The referee stops the game approximately half way through each half to allow for substitutions.
U-19 * 90 minutes (45 minute halves) U-16 * 80 minutes (40 minute halves)U-14 70 minutes (35 minute halves) U-12 60 minutes (30 minute halves) U-10 50 minutes (25 minute halves) U-8 40 minutes (20 minute halves) K 32 minutes (16 minute halves)
*Due to High School, Divisions 1 & 2 follow slightly diifferent rules for substitutions. (See your coach for specifics)
As most people know, the goalkeeper is the only player who can touch the ball with his hands when the ball in the penalty area that he is defending.
The keeper can not use his hands outside the penalty area and must abide by the regular rules.
That sounds simple, but these are the conditions:
The other field players can use his or her hands only when the ball is out of play, such as for a throw-in, or to set up a goal kick, a corner kick or a free kick. If a player touches the ball with his hands at any other times, the opponent will be given a direct kick.
A goal is scored when the entire ball crosses the goal line.

The ball is out of bounds when the ball goes completely over the sideline (touch-line) or the end-line (goal-line). If the ball is touching the line even a little bit, it is still in play.
(Note: A player may be out of bounds as he plays the ball but the ball must still be in bounds.)
The team that last touched the ball as it goes completely over the touch-line, or goal-line, must give the ball up to the other team for the throw-in, goal kick or corner kick.
Touch-line: If the ball goes out at the side-lines, the ball is thrown in by a player of the team opposite the player who last touched the ball as it went out of bounds.
For a throw-in to be legal, both feet must remain on the ground during the throw and the throw must be delivered completely over the head with both hands (one on each side of the ball) in a smooth motion without twisting the ball. The thrower can not throw the ball to himself.
Goal-line: If the ball is put over the end-line by the team attacking, such as by a shot on goal that missed, the team that was defending gets to take a goal kick from within the goal area.
If the ball is last touched by the team defending as it goes over the goal-line, such as by a deflection by a defender or from a goalkeeper save, the team that was attacking gets to take a corner kick.
In the past few years, there has been some concern about the dangers of heading a soccer ball.
There has been no proof whatsoever that heading a soccer ball correctly can cause serious damage to your head. But definitely have the coach show your child where to head the ball correctly. (as shown below).
The front of the skull is one of the strongest bones in the body (as it protects your brain). The top of the head is the incorrect place to had the ball!
