As a homeschooling family, my wife and I are very involved in our children's education and since we're both a couple of nerds, much of our children's education is done on the computer. I use Linux for work almost exclusively so I was a bit curious to see if there were any good children's educational programs for Linux; it turns out that there are some very good ones and I'm going to discuss 3 of them today: Tux Paint, Tux Typing, and Tux of Math Command. Do you sense a theme developing here?
