Math-u-See: I still love it. I still believe he pirated it from Mortenson Math, but he has much better workbooks. I highly recommend getting the VHS version because you will spend much less money. Obviously the VHS version has been discontinued and turned into a more profitable venture by breaking each main category into its own level and has probably been changed somewhat, but the old way works very well. Math-u-see has a website with lots of review material right there--very nice, but I haven't used it much. If you can get your hands on it, the workbook with extra practice sheets is a nice addition. You won't always use it though. (At least I haven't.) If you don't have manipulatives, Math-u-see sells a small set inexpensively. If you have Saxon Math manipulatives, sell them. Mortenson Math manipulatives work very well. Another reason I believe he pirated it.
