I like it alot and so do my kids! This year the twins are starting 1st grade and my eldest will be in 3rd grade and we have been using Singapore Math for 2 years. My eldest son was in the public school for the last 3 months of it last year (the result of a cross-country move and not much knowledge of the homeschooling laws here) and when he took the Stanford 9 test, at the end of second grade, he scored in the 98th percentile.
