We've dabbled in Kumon workbooks. They are really great for giving your child confidence and repetition in doing math facts. Alot of kids where we live go to the Kumon Center for hours each week and just drill, baby, drill! on their math facts.
That would be just way too boring for us. The weakness, I think, for Kumon is that it lacks creativity and supporting problem solving skills. It also doesn't really teach you the topic- it sort of assumes that you already know the skill. Singapore Math also doesn't teach new topics that well but was pretty good for problem solving skills.
My third grader is just finishing the 5th grade math workbook put out by Bright Child. It's pretty good. At least it explains things a bit, and he is smart enough to figure out the rest. I'm going to start him soon on the 6th grade algebra one they put out.
