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?????
That's the point.
It won't be "higher" math, anymore.
To borrow from your own example, how many FReepers have any more than a vague idea (including myself) to what you're referring?
