> No we don't all know that. So I would question that assumption. There are many, many bad elementary school teachers. Moreover someone who understands a subject at a very deep level is more likely to be able to convey it in a simple to understand framework. Example Richard Feynman in physics or as to chess think English GM Michael Stean's "Simple Chess".
Ok, of course they are exceptions, it was just an expression. I wanted to say that a good elementary school teacher is perfectly competent to teach elementary mathematics and that his/her lack of PhD doesn't mean anything when it comes to teaching beginners. Yes, someone with PhD in mathematics can be a good teacher as well, but his PhD doesn't have anything with do with it, there are other skills which are much more important when it comes to teaching elementary maths.
