Visual explanations of geometry, trig, and calculus made sense. But as a kid I never got the multiplication thing. Even now as an adult I understand what they are trying to do, but it isn't "obvious" to me.

Heck as a kid I read illustrated books and didn't realize until I had finished the book that it even had pictures.
