Geenogee has some new math clips up on YouTube. I haven't seen anything out of this guy in ages, I guess he's still around because these were just added about a month ago. I put this in product discussions because typically, he sells his items via ebay or his personal website, so I'm going to keep checking for the full version there. If/when he updates his store(s), I'll add a link if I remember to check back. I like to use a wide variety of programs at the same time for reinforcement, and this is just one more way to expose my kids to math.
Until there, check them out here.
