Hello all,

I'm looking for some collective wisdom. My older child is fascinated by series and sets/set theory (ze's been reading "The Cat in Numberland" and loving it). My knowledge of sets/theory is based primarily on my seventh grade "honors" math class in which the teacher was prone to telling stories about how to capture bats, should one accidentally come into your house. So I am not a great, or even good, source.

Does anyone have any experience with finding a tutor who has an extremely deep knowledge of a particular subject (e.g., set theory), but who also can handle a six year old (who, for example, thinks that bathroom humor is HILARIOUS)? How do I even start?

All thoughts/insights/experiences/warnings welcome - thanks!
