This is one of the simplest, yet most challenging drama games. Sit or stand in a circle. The idea is for the group to count to twenty, one person saying one number at a time. Anybody can start the count. Then a different person says the next number - but if two or more people happen to speak at the same time, counting must start again from the beginning. It is possible to get to twenty if everybody really concentrates - but try and be relaxed as well.
A psychological but fun group dynamics game from Augusto Boal. There should be no talking until the exercise is over. The group sits or stands in a circle and closes their eyes. The leader tells them that one person will be selected by a tap on the shoulder. The leader walks around the whole circle, then asks the group to open their eyes. The group members must look around and try to guess who was chosen. They are asked to remember who they decided upon but not to reveal it at this point.
