I'm not a child psychology professional: I bought this book to help me to address behavioral issues for my own children. As a parent with limited experience in anger management, the introductory material ("Theoretical and practical background") was helpful and informative. It presents the basic theory of how anger manifests itself in children, describes the key objectives of managing anger in children, and reviews basic techniques. In particular, it points out special aspects that make anger management different for children, compared to adults.
The games, on the other hand, did not seem to have very much to do with anger management, per se. They consist of a nice collection of social interaction games (introducing yourself to others, using language to describe subjective experiences, variations on "telephone," variations on musical chairs, collaborative activities (story-telling, drawing, etc.), memory games, pattern recognition games, etc.). Having minimal experience with anger management, I was expecting a more direct connection between the anger management strategies described in "theoretical and practical background" and the games themselves.
