To cc6 (sorry, very much don't want to derail the thread, so please ignore at will): one game that worked for our DD was "multiplication war"; you just play regular "war" (i.e., dividing a regular card deck in two and each player putting down one card at a time; higher card wins) with this variation: each player puts down two cards at a time; the player with the higher multiplication product wins the round (you can do face cards = 10 points, or whatever). This is a great idea that came from my DD's wonderful Montessori teachers (as opposed to her awful ones), but of course you can see it can also be used for all of the basic math facts with just a few changes. I hope that helps; I'm not sure what to suggest re the shutting down. Best of luck!!
