Hmm...I now know of two ways to do multiplication using fingers, and I'm not sure which one you are talking about. There is a cool book called Fingermath that I picked up at the library book sale and got addicted to for a while, and I like its methods. Then there is the stupid thing that my DS6 learned at school (I think...he may have made it up himself) that is really keeping him from just memorizing his multiplication tables. He counts up from the last one that he knows, basically. And when I try to free him from that, because I know he could simply memorize the tables in a day if he made up his mind, and he knows half of them already, he freaks out about it. Arrgh!
