The “short, old fashion way” only works for a very limited number of problems. When you get any more complicated than “2+2,” you have always been expected to show your work.
It may well be that this new method enables people to more easily handle math related issues in their day to day lives, but I believe I am destined to make do with what I've got, which seems to serve me well.

See post 39. I can do quite a few computations in my head. I don’t need to “show my work”. Yes in more complicated areas you need to systematically work a problem but most common math does not need this. You have failed to show how Common Core helps very young learners in math. There is no logic in the manner of some of the groupings unless you know higher math.
Let me make this simple for you.
Imagine someone knowing verb declensions who is starting to take Latin. In fact they have to already be familiar with declensions to understand what you are teaching. Yet they have never taken Latin before. Understand the problem?????
