I think Common Core is intended to isolate the children, make them children of the “state” by convincing them that their parents don’t know anything (Common Core) but the teachers at school know everything. Parents can’t help kids with their homework but the school can. I think it’s a means to train the children to look outside the home for knowledge.
Good point, I would add whether it is intended to do that or not, that is what it is doing.
Isolating parents from children.
I don't know if it's intentional but you are dead on about the result. My third grader pulls out this sort of overly complicated baloney and I say "no no no, it's actually easy if you just...." and she cuts me off, tells me she's not allowed to do it that way and the teacher will know because she has to show her work. Then she cries because she can't figure it out and says she's a failure.
