The Coach as a Role
As a coach you must set the mood, start the activities, have the overview, step ind and change the activities if required, help the participants, instruct and monitor the physical aspects, and ensure that the rules and forms of the games and exercises are kept.
If you can, do participant in the activities. Often the kids finds this is fun, but do not participate in team activities unless you are more than 1 coach, one on each team.
Try to use your strength and abilities at a level that corresponds with your students age/abilities if you are participating.
