This game blends Cognitive Behavioral Therapy and Play Therapy to help children become aware of their thoughts and filter out negative or irrational thoughts.  To play this game, you will need a paddle, a bag of pompoms, and a bucket or box.  I was able to find all of these supplies at Dollar Tree.  I bought a paddle ball game.  I removed the ball and string before use. 
 
This game comes with full instructions, prompts while playing the game, and discussion questions for after the game.
