Have you ever met a kid who was excited about doing math the Common Core way?
One of the issues with Common Core Math is that it really teaches children to jump through the hoops of diagramming the way the book says to do it (and that way is cumbersome), not actually solve problems or understand concepts. People model ideas differently, Common Core requires one overly pedantic way of doing it, for the intelligent who figure out a better underlying representation, the Common Core Math Way(!) is drudgery. That just means more hatred for mathematics. It would be better to show examples and ideas, get interest and excitement, then formalize, but formalize in a way that is useful later on.
Mathematics _is_ exciting, it is a puzzle. Teaching should reflect that.
