Anh is building a big tower and his grandfather tells him to come and eat dinner. Anh wants to continue building his tower because he wants to build the biggest tower. Anh's grandfather tells him again to come and eat. Anh becomes very angry and unable to speak and his knocks his tower down. His grandfather then tells him to go to his room and sit with his anger. Anh throws a fit in his room and a red hairy monster shows up and tells him he is his anger. The monster helps Anh understand his anger and how to work through it. Anh's anger tantrum begins to exhaust him and him and his anger eventually sit silently still and begin to breath slowly. As Anh is breathing slowly, he begins to feel better and his anger becomes smaller and smaller. This book would be great for K-3rd grade because it teaches students that it is okay to feel angry and that anger can go away when you sit with your anger and began to breathe slowly.
