        1   .Being angry doesn't really solve much, but what people do when they feel angry is important.

The goal is to calm down and try to solve what is bothering you. This is hard for some kids and adults,

too. Instead of calming down, some kids might keep getting more and more upset until they explode like

a volcano!

       2    .Their anger might be so strong that they lose control of their temper. They may act in ways

unacceptable and hurtful. People may say that someone has trouble controlling their temper.  3  

Some kids might get so angry that they scream at their parents, break something , or even worse , hit

their brothers or sisters.  4   .However, it's not OK for a kid to do any of those things .Kids don't want

to act in this way , but sometimes angry feelings can be hard to manage. So what to do?

     Well, the good news is that kids don't just have to keep making the same mistakes over and over

again.  5   .Imagine your temper as a puppy inside you that needs some training. The puppy is not
