Absolutely! There’s nothing wrong with staying within ones comfort zone...until you can’t.

Admittedly, I’m old school too, but I have enough background in higher math to see what they’re trying to do, and it’s a sound approach that will put the average kid on par with “our” best math students.

Sorry I just read this reply.
No it will not put our kids on par etc.
Why? Small children are concrete thinkers. Abstract thought comes later. This only makes them confused. We had old methods of teaching that worked. But heaven forbid lets do something that was never Beta tested and was not thought up by anyone who ever set foot in a lower or even high school classroom.

That's reasonable. Perhaps the benefits of teaching "mathematics" via this new line of understanding/comprehension will bring about a much-improved and independently-thinking citizenry, superior to the slide-rule users, in the next generation or two (or three). Or perhaps...not.

(Neither you nor I know how this will turn out. You are much more optimistic than am I.)
