Three by Four
Adapted from "Two by Three by Bradford" in Augusto Boal's Games for Actors and Non-Actors.
Team of three. Player one says, "One". Player two says, "Two." Player three says, "Three." Player one says "Four." Repeat the sequence again and again, picking up speed.
Once the team is smooth, the joker introduces a sound in the place of "one." The teams play again, this time using the sound in the place of "one."
Once the team is smooth again, change the sound into a word.
Repeat until all four words have been replaced by words and the team is saying a sentence.
