Good to remember, when you are having a bad day would you want someone to make it WORSE? Kids don't always know how to say what is bothering them. Be their savior NOT their problem or antagonist. They will value you for it.
Power Cards are often used with Autistic children, but I believe they can be helpful for all children. Power Cards are highly visual and they contain short blurbs or lists of information that will help a child in various situations that he may come across.
