While we at MC2 don’t directly run contests, we know that some of our students find them elsewhere. One contest you may not have heard about is “Who Wants to be a Mathematician?” Kids from anywhere in the US can enter, and ultimately you earn a free trip to San Diego to attend a final contest with a $5,000 grand prize.
Interested? Check out this website, and get your classroom math teacher to email paoffice@ams.org to say you want to enter (or email them yourself with your teacher’s name and email address)!
