This is my fourth year of not substituting in a public school urban environment, after 7 years of that adventure. Common core was just coming in. It's a nightmare. Teachers are told not just what to teach, but how to teach it. It's very difficult to time your teaching to take advantage of it when a student is ready to break through. Everything is manipulated.
I agree with everything you say. That's why I'm saying that it doesn't seem that the unions really want to get rid of Common Core. If they'd stood on that issue, they could've DEMANDED someone that was 100% states rights for curriculum and other education initiatives.
Like the majority of unions these days, the "union" (i.e. union leaders) don't really give a damn what the union members want.
