I Tweeted this last night and it got reTweeted a bunch of times so I thought I should share it here for people who missed it. When I was in elementary school I really enjoyed watching Mathnet on PBS. For those that aren't familiar with it, Mathnet was part of Square One which was a show designed to teach math lessons in a fun way. I did a quick search on YouTube for Mathnet and sure enough many of the stories are available in their entirety on YouTube. I don't know what kind of copyright restrictions are or are not being broken by the people who uploaded the videos, so I can't say if the videos will be up forever. In the meantime if you want to show an episode to your students or just want to feel a bit of elementary school nostalgia, I've embedded a few episodes below.
And who can forget Mathman?!
