My 9 year old daughter loves math and is getting quite good at it (she can derive the quadratic formula from first principles, knows a few other basic proofs, and can factor big numbers faster than I can). Unfortunately, although she has a good number of friends, none of them like to talk about math, so I'm her only "math buddy".<p>I figured someone here might have some ideas for finding some math community for her. Preferably in-person (in Washington), but virtual could work too. Thanks for any suggestions!
Art of Problem Solving & Math Olympiad have communities everywhere and she can hang out on their forums and start practicing past contests.<p>Get her a tutor from Preply (you can find incredibly affordable math tutors in foreign countries) and have them work through past contests.
There's Khan academy which is free. (Online)<p>Are there advanced classes for her to take in your school district?<p>Then there's math competitions.<p><a href="http://hub.wastudentmath.org/Competitions" rel="nofollow">http://hub.wastudentmath.org/Competitions</a><p>Wish you & daughter success.
