Team Building

This past weekend I had the privilege of taking 24 adult volunteers and student leaders to Lake Aurora Christian Camp in Lake Wales, Fl. for a day of team building and connecting. They have a low ropes challenge course where we divided into two teams that were lead by some camp employees. It was so cool to watch some of our student leaders and volunteers work together to accomplish the particular task at hand.
Examples of the tasks were: "Truth Fall" - each team member is asked to climb up a tree to a platform about 4-5 feet up and stand on it, turn back ward and fall into the arms of your team-mates. "Spider Web" - pass your team-mates thought the holes made from a rope that is stretched and staggered between two trees that creates a web like deal. There were several other tasks, but you get the idea.
In my opinion this day was one of the most productive team building and empowering events we have ever been a part of. It was an event where we all learned the importance of communication and encouragement. Communication was completely necessary as the teams set out to accomplish a particular task. Student leaders would talk to adult leaders and vice-versa. Age wasn't an issue. Adult volunteers would encourage a student leader. So much accomplished. So effective, yet simple.
What types of activities have you lead your teams on? Do you have leadership training days? If so what do you use to train?
