what after math mammoth?

I went back to MUS.  I have used just the blue series to review better, and I have used two years worth of light blue full curriculum.  Thsi year, I moved my fifth grader back into MUS, because at the end of next year I’d have to choose to move him into something else anyway.   He’s doing just fie back in MUS.  I don’t love beta, gamma, or delta.  Epsiolon is ok.  I wish there was more real life, different approaches to solving word problems but I think you just can’t beat the ease of use for MUS.  I think that the way Maria Miller teaches multiplication and long multiplication and fractions – it’s all so excellent.  Better than MUS, IMHO.  But I missed the simplicity of MUS.
