I had the same experience— as a kid I realize now I just learned how to push numbers around on a page; after teaching elementary math I have a fundamentally different (and to me, better) understanding of how numbers work. Kids shouldn’t have to wait.
It wasn't until I taught elementary school and found myself breaking this down for young kids that I realized the difference. The old way did me a disservice that I see the impact of every day. I'm so excited that my daughter (a future DISD student) will be better served.
