As a matter of fact...
In third grade I was seriously excited when I figured out a way to take more away from less (that's how I thought of it)
The teacher absolutely and authoritatively told me it was not possible and to behave and do the problems.
It did stick and was hard to unlearn.
Its another matter to expand learning. Fractions were major fun..the did not falsify whole numbers, they added.
Look, I'm seriously bad at some things. Music for one; however much I enjoy it, I really don't understand it. I don't try to teach it. I could only do harm.
From what I am hearing from y'all, is that we shouldn't teach the theory of sound unless the model is accurate in the strict sense of Quantum Mechanics.
