Is this literally about states that have poor math achievement, or is it along the lines of some states aren’t teaching math because <insert culture war things>? It’s become difficult to tell when a good faith discussion on public education is happening.
California is considering copying San Francisco's ban on teaching Algebra to 8th graders. So maybe more imagined than real, but real for a small number of people.
My experience is very old. I went to one of the most highly rated county school systems in the US. The quality of math instruction was horrible. It was called new math back in the 60’s. I think we are on at least the third iteration, new new new math. In grad school I finally had a good teacher.
