It’s been awhile since I’ve posted here, but I’ve been posting like crazy to the http://mathmojo.com/kenken page. I’ve already got 24 videos up about how to do KenKen®, from simple 4×4 KenKen, to sadistic 9×9 KenKen puzzlers without operation signs.
I’m finding that the feeling I get from KenKen is similar to that “numbers juggling” feeling I get when I do mental calculations, like large multiplication problems.
It’s possible that KenKen is about the best mental fitness activity you’ll ever come across. If you homeschool, there’s nothing better you can get your child into. Check out the http://mathmojo.com/kenken page to find out more.
