Danica McKellar, the actress who played Winnie on the Wonder Years, is a math whiz! She's written a book aimed a middle-school girls because studies show that's when girls start to lose interest in math. Danica says, "If you turn on the TV, it's all about how you look. I want to tell girls, Go ahead and get the cool makeup - I do! But know that being smart is an essential part of the package, and math makes you smarter."
