Sorry for happening by this thread a bit late! I have a 9 yo who doesn't know all of his times tables yet by rote. We're working on it, though. Once I showed him how convenient knowing them all was for long division, he saw an actual use for just knowing them because it gets the problem done faster.

I am curious as above the Memorize in Minutes actually piqued my interest. I recently watched a show - Redesign my Brain - which used that type of technique for memorizing playing cards and remembering people. (http://www.abc.net.au/tv/programs/redesign-my-brain-with-todd-sampson/)
