This is the thing that really baffles me. My kids went through K-12 when Common Core was a thing, and there was a huge backlash about it, so I decided to look it up and to see how it was being used in our school district.

A few states published their Common Core guidelines. I looked at one state, and the curriculum goals looked no different than the things that I learned when I was a kid. It seemed completely ordinary. I remain baffled about why it was so controversial.
