What a great book! I am a high school teacher, and I'm not only trying to teach my students about literature and grammar, but also about teamwork, cooperation, and communication skills. This book has lots of activities that are divided into 4 levels from learning peoples' names to really opening up and sharing personal stuff. The instructions are easy to understand, and most require little preparation and supplies that you usually have around (pens, paper, tape, chairs, etc.) The book is well-organized beyond the 4 activity levels as well; for each game, the author clearly states the objective, the needed materials, instructions, and variations on the activities. For the second two levels, she also includes excellent discussion questions. It seems to me that these activities would really work with ANY group. Well worth the investment.
