Therapeutic games are great but usually pretty expensive. Children and teens disclose and express a lot more during games than if I were to just ask them questions. One way I keep the cost down is by buying low cost regular games and give them a therapeutic twist (see jenga and feelings tic-tac-toe posts).
Bare Books has really cheap blank game boards, books, puzzles, etc. A professional looking blank board game is just $3.95. They have flat rate shipping so I suggest getting together with a couple people to place your orders. Click the photo to check it out.
