corbie Posted June 15, 2009 Share Posted June 15, 2009 Has anyone used Math Mammoth as their spine for math? (Light Blue series) I'm considering it. It seems straight forward, short - to the point lessons, self explanatory, and inexpensive. I have MUS blocks and tons of other manipulatives to help. I'm looking at Light Blue 2b or 3a. I like the emphasis on mental math. Any opinions? Quote Link to comment Share on other sites More sharing options...
