I don't normally pimp websites that sell stuff, but if you want to get into math, check out the Joy of Mathemathics dvd available at The Teaching Company - www.TEACH12.com . It's a very entertaining introduction to some of the amazing things you can do with math. I've been watching it with my 8 and 13-year-old kids and while some of it's over their heads, they get most of the concepts very quickly, and we've have none of the usual "math is boring" complaints. But don't pay full price - the prices look outrageous, but they seem to put everything on sale once a month or so for much more reasonable cost.
