I just read this National Review article [1] criticizing common core, but it all kind of makes sense to me. I get that when you have 6 of soemthing and visually move 4 away, two things remain. IS there something more insidious I'm missing here? Is the idea that 82 is 0 hundreds, 8 tens, and 2 ones all the crazy? I kind of like it. But, I don't have kids and the only thing I ever taught kids was how to tie knots and sharpen an ax at summer camp, so what do I know.
