Common Core seems pretty stupid
My kids are long out of grade school so they, and I, were never burdened with learning math any way other than the tried and true way it's always been taught....the old fashioned way.
It is my understanding that as part of the Common Core teaching strategy, 2nd, 3rd, and 4th grade students are given different ways to work problems such as the one in the picture.....to train them to "think" about it correctly. I get that, but I've heard many frustrated parents say that their kids are being forced to learn math the new, convoluted way, even if they understand it the old way. My colleague here at work says that her daughter can work 3-digit addition/subtraction problems the old way with "carrying" and "borrowing", the way we learned it as kids. But if she arrives at the correct answer and didn't show her work the new way, which neither she or her mom can make sense of, then she receives an "F" for doing it incorrectly, even having gotten the right answer.
Am I missing something or is this how Common Core is taught in grade schools now?
I'd like somebody to explain the problem above to me. Where did the numbers in the box come from? And how does doing the problem this way make the concepts more understandable and clear?
