Your argument against Common Core is a meme.
The reason why
some people with college degrees don't understand Common Core approaches to math is because math has been taught in a one-size-fits-all way. Instead of a true understanding of math, it provided a method for solving problems that are meant to be memorized, but not necessarily understood.
Common Core standards understand that there are different approaches to solving math problems, and exposing children to different ways provides for a a deeper, meaningful mastery of those concepts.
But your cute meme is noted.
