Freeze
Instruct all of the children to stand around the stage area in a large circle. Select two kids as the first actors. These initial actors will step into the circle and begin acting out a simple scene of their choice. Once the rest of the group has begun to understand the premise of the scene, anyone within the circle may yell "Freeze!" The actors must immediately freeze, and the child who yelled freeze is to step into the circle, tap one of the original actors on the shoulder and take their exact position. Once they are in position, the the new actor must change the topic of the scene. This process continues until everyone in the circle has participated. (See Reference 1.)
What Are You Doing?
Ask the children to stand in a line at the edge of the stage. When the activity coordinator indicates to do so, the first child runs to the center of the stage and begins to act out an activity with no words. As the coordinator shouts "go," the next participant runs on stage and promptly asks, "What are you doing?" The first actor must immediately answer with any activity other than what they were actually acting out. The new actor is to quickly begin pantomiming the activity answered by the previous actor.
Subtitles
Instruct part of the group to work together and act out a scene from a popular movie. However, the actors must all speak in a "foreign language." This language does not have to be real, but should have a certain accent to it. Another actor translates each spoken line to English. The end result should be a fun translation that's nothing like the original.
One Word at a Time
Standing in a circle, children hear the topic of a story by the group's coordinator. Children then start telling the story one word at a time as each person in the circle contributes a word to the story. Encourage participants to create a story that is creative while remaining coherent.
