I know everybody loves Singapore Math, but I didn't love it for my kids when we casually tried it for aftersschooling. I'm afraid I forget exactly why.

I believed DD is using a Harcourt-Brace series now. It seems oddly easy compared to last year's book, which was both challenging and poorly written and conceptualized (a weird mix). I don't feel like she's learning as much this year, but at least the book doesn't have errors and confusing problems. Note that this is her fourth math curriculum and she is in fourth grade (but did switch schools once).
