Your son is just a tad young for the age groups these books are aimed at to read by himself. The rant and rave on wednesdays is aimed at 9 an up, but he may be able to read them. The first set mentioned is aimed at 8 and up.
You might want to check out "When I feel angry" which is aimed at preschool to about age 7 http://www.amazon.com/When-Feel-Angry-Way-Books/dp/0807588970/ref=pd_sim_b_3?ie=UTF8&refRID=1M8V5EXPFNAPZD9WFW8P . It also has several other good choices listed on the bottom of the link.
It would be a good idea to read all of these with your son so that you are also aware of the techniques. And they should probably be read more then once and maybe even acted out. When he does get angry, then you can remind him of things he can do. Probably the most important thing is for him to be able to recognize that he is getting angry.
Thank you. His in 1st grade now. His anger started when I got a divorce but it stopped and now is coming back. His teacher believes it is the only child syndrome because he is use to being 1st at everything and his anger often happens when he is not selected for something in class etc. I will check out those books because he loves to read.
By now a bright child should have been able to figure out when or when not to talk at school. Early in the year, when kids are figuring or testing out the system - yes, certainly easy to get called out for talking. By now, it should not be going on. So there is an indication of a problem either with the teacher or the child. And, actually, boredom is a problem for bright kids at this age and not knowing how to deal with it.
Did he have same problems in first grade. If not, that might indicate more of a teacher problem. If he has had the same problem for 3 years, then other things could be going on.
But to answer your question. kids do need to be taught how to handle their anger. There are a couple sets of books aimed at this age group. One is, " How to Take the Grrrr Out of Anger" (Laugh And Learn). That and several more are found here - http://www.amazon.com/Take-Grrrr-Anger-Laugh-Learn/dp/1575421178/ref=pd_sim_b_7
Another good set is the," Don't Rant and Rave on Wednesdays!" The Children's Anger-Control Book. That and others in the set are found here - http://www.amazon.com/Dont-Rant-Rave-Wednesdays-Anger-Control/dp/0933849540/ref=pd_sim_b_1
Hope this helps.
