what kind of work do they have you do in anger management classes?

Found this, it may help:

"A common skill used in most anger management programs is learning assertive communication techniques. Assertive communication is the appropriate use of expressing feelings and needs without offending or taking away the rights of others. It is typically started with the use of "I" statements followed by a need statement. For example, "I feel upset when you don't take my feelings into consideration when you talk about your past relationships. I hope you can be more thoughtful and know what you should and should not say the next time."
