Kids who have self-awareness do a better job self-monitoring. That means your child is able keep track of what he’s doing (either in learning or socially) and figure out what’s working and what’s not working. Self-awareness also leads to self-reflection—thinking over things that happened in order to find ways to make things work better next time.
The Anger Iceburg is a way to show students that sometimes anger is an emotion we use to cover up other emotions we don't want to show. Maybe you're embarrassed and instead of showing that emotion, you show anger. Learning to identify when anger isn't really what we're feeling is a great way to show students how to cope with those emotions.
