It would be entirely possible to teach advanced math topics to younger using just pictures.

One example great example is the pythagorean theorem which can be demonstrated with a series of triangles and squares.

I do not know of any current books that has done this to a degree a five year old could learn from, but there is a huge opportunity here.

The book How to Teach Your Baby Math touches on some of the fundamental differences between using visualization and symbology.
