When I first saw the Common Core way to subtract and add and whatnot, I actually really liked it. It was very more, uh, how would I put it. It felt more like what I identify as Mathematics.
This stuff here just kinda helps me think more like that it's preparing students more for the analytic and problem solving portion of Mathematics rather than the calculation aspect. Which I think is good. I think brute force calculation is kind of good to have? But I always thought there was too much. Especially for the fact that I have a phone next to me that beats me in being able to solve differential equations by far.
This is the start to analysis. Throwing more word problems and things like what were in that test at people means they'll have to understand how to analyze a problem or they'll fall behind. Which yeah, kinda sucks for some people. Pretty much everyone in my high school math classes didn't know how to do this, and maybe a fourth of the people in my honors sequences+series calculus classes in college didn't really know how to do it. Pretty much anyone I help out with Mathematics at a lower college level (Basically linear algebra and below) have those issues with analysis and problem solving (Which is probably the reason I'm helping them in the first place).
The society that exists nowadays just needs the analytic portion of this stuff more than it needs the raw computing, so I personally like the direction this is taking. It's more important to kinda get a feel for understanding why you are doing these steps and getting some sort of underlying feel to the process nowadays than it is to be able to crank out the process over and over when you can easily just be outclassed by a computer in basically any form of computational math out there.
I haven't looked more into it, I could imagine that it would be a total pain as a parent. I've heard literally all of my old teachers complain about it, but I haven't actually talked to any of my old math teachers now that I think about it. I'm not sure if it would be a pain as a current-generation teacher, maybe one that has been teaching for a while.
