I adapted this brainstorming game slightly from an activity in the book Intraemprendizaje by Iñazio Irizar (http://intraemprender.blogspot.com.es/).

1. Players seated in a circle, one person standing in the middle points to a player and says, "C!" The player has five seconds to say a word starting with C. If they miss, they go to the center.

2. In Teams: given a theme or object, people brainstorm words related to that object that begin with C.

3. Sound Challenge
Players seated in a circle, one person standing in the middle points to a player and makes a phonetic sound (for example one of the sounds on Don Cherry's version of the Gattegno sound color chart -- "buh"
The player has five seconds to say a word starting with that sound. “Bat!”
If they miss, they go to the center. Matt is the referee.
