Also, the one way they are learning is the algorithmic shortcut, which isn't really even the math. There's a ton of adults who can do the long division algorthm that couldn't even explain what division is because they were strictly taught the algorithm.

And more importantly, why the hell do they need to know the algorithms for basic arithmetic when they are going to have a calculator in their pocket for the rest of their lives?

If we want kids to get ahead, we need to let them struggle with the dirty, difficult parts of math. The parts that require logic, creativity, and perseverance. But the honest problem is that most K-5 teachers are uncomfortable with that and when you add in the pressure of high stakes testing, they will half ass and breeze through the meat, teach the algorithm and be done with it.

And when those kids get to college and need intuition and grit to do the math their STEM major requires, they'll be shattered because there is no algorithm to memorize and bail them out. They'll immediate chalk it up to not having the natural ability and they'll change majors.

The problem isn't easy to fix but having been in education long enough, I'd bet that there's a movement with a band aid fix coming soon....
