I dislike common core for any number of reasons
That said common core are a set of standards not the metjodoligy. The stupid PhD in math who decided that elementary school should be able to do anything more than memorize tables and utilize them is insane. Concrete thinking doesnt even begin until age ten or so Abstract thinking (draw a conclusion) doesnt happen until even later. Asking young brains to do what they neurological can not is just plain stupid
And I thought the new math they taught us in the sixties was bad
I remember that being told to us.
Pissed my Dad off. He had ONE math book for all off high school. He became a EE.We still his math book. It meant that teachers had to teach.
