Keep an eye on what your kids are seeing online. Parents need to stay involved in what their children are being exposed to. It's so important.

I want girls to feel the confidence you get from being smart. They get so many messages that tell them the most important thing is to be beautiful.

What I got which was unusual, especially as a child actress, was parents who believed that Hollywood was not that important. They told us education, family, health, all come first and they meant it.

So somebody told me that if I wasn't a coffee drinker yet, by the end of college I'd have to be, because a math major is so tough I would have to stay up very late. I was going to need coffee to do that. Well, merely because they said that, I never drank coffee in college, never got addicted to it, never needed it.

It's a great way to get the kids involved in science and parents are invited to stay too.

My message is: You don't have to give up being popular, fun, or fashionable in order to be smart; they can go hand and hand. Doing math is a great way to exercise your brain; being smart is going to make you more powerful in life.
