We are halfway through Beyond, which is why I'm considering 1B, vs. just starting 1A. He has completed quite a bit of traditional, textbook math. He has his addition facts memorized, as in you can drill them quickly. He can do subtraction, but doesn't have them memorized and it takes some thinking. He just took the 1A placement test. He completed the test right at 80%, which Singapore would consider passing. He missed most of the subtraction questions, as well as some of the problems where an addend was missing: ___+3=13
He has been through so much math, that I'm hesitant to put him at the beginning (1A), but he definitely lacks the critical thinking skills that I know Singapore enforces, as well as he's not up to speed on his subtraction facts. So, for those of you who have been through the program, should I go ahead with 1B, or should we start at 1A?
