Our school was too cheap, said it was too expensive. This was when kids were in elementary, now 10th grade & freshman in college. They probably are still too cheap. I’ve heard mention on various message boards with teachers asking each other IF they’ve started the Common Core, which I’m not familiar with.
I’m not familiar with “Common Core” math since I’ve been retired for quite a while, but I don’t like the word “common”-sounds like a diminished program to me.
