I am a retired teacher (42yrs), and this is an excellent article.  Common Core is/was a fraud thrown on parents/schools/teachers/etc.  We were "forced" to adopt it or face financial consequences.  Schools are forced to "teach to the test" in order to  make sure the students "show" achievement or schools/teachers are punished.  Granted, our school systems need a major overhaul, but this is NOT the way forward.  Our state finally "dumped" Common Core, but in reality kept parts of it and renamed it "College and Career Ready". LOL  same ol same ol...new name/same package.
