If you can swing the extra cost, Mathnasium may be a better fit. Their tutors actually sit down and work with your child, not just correct worksheets done at home. The Kumon price range is somewhere around $100 per month, whereas Mathnasium is closer to $300 per month (just ballparks). OP here, sounds like my DS is more of a Kumon candidate actually. He's in 5th.
