[quote=Anonymous]My child switched from no particular math curriculum, or a loose regurgitation of Investigations (which was abysmal) to Singapore Math in 4th grade (school-wide curriculum). This topic (borrow/carry or regroup) reduced my child to tears in public school, and there was a major fight between teachers about how to teach the regrouping concept, which certainly didn’t help matters.

I’m not a math educator, but maybe some familiarity with a curriculum like Singapore Math would be helpful at this point, even if only as an adjunct to whatever system your child is currently using. Amazon has some of the workbooks, textbooks, guides and errata. My child had to backtrack a bit (the levels are set to have a/b phases for each grade level, with the b level being equal to the first half of the next grade level).

This point might be a good time to work out whatever issues are afoot — they will be prepping for the road to algebra before you know it. Four years, and a lot of work using Singapore Math probably saved my child’s math education. My child will never be an ace algebra student, but is proficient enough to be really solid in AP Statistics.
