Switch, Change, Rotate

You'll need a nice big open area for this one.  Works well with 20 or more for about 20 to 25 minutes.

A sample activity from The Empty Bag

Process:  Ask your players to get into groups of 3-4 and stand in a single-file line facing in the same direction.  This activity involves the facilitator giving specific commands the small groups are asked to follow--to the best of their ability.  First, you'll want to do some practicing with the small groups standing in one place.  The first command is, "Switch."  The player at the front of the line peels off and goes to the back of the line--practice.  Next, say "Change."  The line of players is required to turn 180 degrees to face the opposite direction--practice.  Next is "Rotate."  This command requires the front and back players to exchange places--practice.  Spend a little time practicing with each command while the groups are stationary.  At this point you are going to add the command, "Move."  On this command the groups start walking (doesn't need to be fast) around the room (within the established boundary area) in their single file line formation---the head of the line being the leader.  The lines are allowed to weave around the area as long as each small group stays together.  The last command you will need to give the groups is, "Freeze."  This obviously stops all the action.  So, now the groups have all the commands they need.  Here is the ultimate challenge.  Start out the groups with, "Move."  then begin working in the Switch, Change, & Rotate commands as the groups are walking around.  (If you have some music to play during the activity it gives the groups some beat to walk to).  Give the groups enough time between calls to get into the correct formation.  Be sure to mix up the "commands" so the groups do not know in what order the commands will be given!!  After a few minutes the groups should have it down pretty well.  This activity brings you wonderful leadership issues and how the group members help one another.
