@St_Rev "Does 8+5 satisfy 'has ten?' Yes" But trying to construct a meaning of 'has' that reads 'is' seems unintuitive, maybe unproductive. -
@blue_traveler "If you add 8 and 5, do you have *at least* 10?" "Yes, you have 10, and 3 left over." That's plain English. -
@St_Rev I wonder why there's an attempt at new nomenclature, other than it's "new math" again. Or do you think it's just a fuddled prompt? -
@blue_traveler New Math was a specific movement: https://en.wikipedia.org/wiki/New_Math -
@St_Rev I'm superficially familiar with it, based on a maths prof showing me a YouTube comedy video about it

@St_Rev I thought the point was teaching the cognitive algorithm "make a multiple of ten and add the remainder" -
@Watercressed Not sure what the point of that would be. -
@St_Rev It's similar to way I add numbers, so common core planners might have observed their own thoughts and decided to teach it. -
@Watercressed Ah, possible. -
@St_Rev@Watercressed That's exactly what it is, "make ten" & then +/- remainder. Singapore Math curric & others teach this for mental math

@St_Rev it's so hard to write good test questions that I used to give my students extra points for finding flaws in questions <3 -

@St_Rev "this just teaches them to be rules lawyers" yup they are paralegal students and plus it's fun
