The build-out line is used to encourage the development of play from the backfield. It is used for 3 situations. This video explains it well. https://www.youtube.com/watch?v=sY408eOnAW4
Goalkeeper possession - when the goalkeeper gets possession of the ball, the offense must move behind the build-out line. The goalie may throw, roll, or kick (no drop-kick) the ball to any teammate on either side of the line. As soon as the ball is released, the offense may move forward. If an offensive player moves forward early and interferes with play, an indirect free kick is awarded to the defensive team, placed on the build-out line.
Goal kicks - when a goal kick is called, offensive players must also move behind the build-out line. They may move back over the build-out line once the ball is kicked. The goal kick may be taken early, but if the ball goes to the opponent, play continues.
Offside - Players can only be in an offside position only if they are closer to the opponents' goal line than the build-out line. See the section on offside rule for more details.
A goal is scored when the ball completely crosses the goal line. Coaches may keep score.
At this age, players are more capable of understanding rules and so referees (and coaches) should enforce them with a teaching attitude.
