Under 8 - 11 age groups - Instructing Referee
The main role of the instructing referee is to control the game to ensure it is played fluently and instruct and correct the players (with minimal blowing of the whistle) on how to behave and what the rules are, e.g. what a foul is, what a free kick is and how to throw in etc... Should these indiscretions happen a second time the referee should stop the game and apply the appropriate action and decisions. This person can be a club official, capable parent, older child or player, beginning or official referee from the federation or association.

Some tips;

• Discourage players from permanently standing in blatant offside positions and instruct them to move into
  onside positions. In the Under 10 & 11 age groups children should be made aware of the offside rule during
  training and be encouraged to adopt this philosophy during the game at all times.
