After all those years teaching children to dance, it is no wonder you are fascinated with the developmental differences in your grands. I have similar fun with the kids at TKD...how quickly they grow from awkward to graceful to "too cool" for their own good, as you said.
It is partly the formal skill of assessing motor development I learned in teacher college, and partly reaching back to my own kids' growing-up years. You know how you had to choreograph to work with each stage of development...it is really a trick to teach a five-year-old a formal poomse, when right and left are still kind of "out there" for them.
Dance and martial arts are both wonderful ways to help them gain coordination, balance, and the ability to concentrate...not to mention, self-confidence.
People-watching is a great form of free entertainment, isn't it?
