Cyberchase is a PBS show for kids that teaches math. It’s designed for children 8-12 but my 5 year old loves it. I’m impressed too. My son picked up on the concept of negative numbers from one episode involving an elevator traveling from above ground to below ground. In another episode, the cyber-kids use backwards induction to save the world! The cyber-kids even figure out the value of having a medium of exchange. If you have kids, check it out.
I also recommend, Between the Lions, the hippest kids tv show I have ever seen. One episode featured the music of Charlie Parker, recurring bits are Dr. Ruth playing Dr. Wordheimer (she counsels words on how to blend together), Martha Reader and the Vowelles, Gawain’s Word and more.
