Wash your mouth with soap.
I pay for my grandkids to go to private school just so they will not learn "common core" math. The giants of the past: Einstein, Maxwell, Newton, Fermi, Lawrence, Edison, etc. never spent one second learning common core math.
You are correct but I taught math and my school required I use an outline provided by the state (CA) I had no problem doing this as I knew my subject and taught what had to be learned and work the required material. (and yes, I was able to demonstrate that I taught the outline too.
Only meant I had to pay attention to both, but I still got to teach math. And while they tried to mess with my HS math with the “new math” I still managed to get the true hang of the subject and good teachers (and I put home school teachers in this category) will do the same regardless of what useless laws the state of Mississippi come up with.
