Baldwin’s Big List of Math Videos

Over the years I have shown kids math problems on You Tube videos. I have a collection of them here on this list. I do them on the fly and once in a while I make incredible mistakes, but I just let them continue to exist. So you may see and hear me make outstanding stupid errors, just deal with them. If you can’t find one that helps, holler to me and I’ll possible whip another one up for you.
