6. Maybe think of some fun math puzzles?

I eventually majored in math, and I was mostly motivated early-on by math problems with solutions that surprised me, going against my intuition at the time.

My father often gave me those kinds of problems, like this one:

Obviously, it would need to be done with whatever the child is currently learning.

My Dad even gave me the "Three Utilities Problem" when I was a little kid, but that didn't seem very mathematical to me back then.

All that I knew was that it seemed to be impossible, after repeated tries, so I gave up. Yet that puzzle stuck with me, and I recalled it while taking a "Graph Theory" class in college. Then I used that new knowledge to PROVE it was impossible, which was about an 8-page proof for me I think. I did that just for "fun" back in those days.
