I did this intuitively, but i teach my kid this. Like if you had 62 + 87 you can do it the way we were taught of writing them on top of each other, or you can add 60+80 and 2+7. Sometimes it makes things easier.
I do think that kids should just memorize shit and learn the theory later, especially with algebra onwards.
