Event Information

  • The individual round consists of 4 sets of 8 problems each.
  • The team round consists of fewer but more challenging problems aimed at testing a student's depth in mathematics.
  • Teams consist of 6 people each. Participants can form teams beforehand, but they all need to be in the same grade. If participants do not have a team, they will be put into teams on the day of the tournament.


Toy Drive

OCMC not only strives to inspire young mathematicians, but it also provides some students with financial need with an interactive learning environment. (We also teach math in the Santa Ana Unified District to students who have the passion but lack the resources to become mathematicians.) It's the holiday season, and we would like children to have a warm and merry Christmas with presents. We encourage you to expand upon our cause and make a difference. All volunteers and participants, please consider bringing in a new, packaged, but unwrapped gift valued at $5-$20 to the Thanksgiving Tournament. Thank you for your donation! Your generosity will touch a child's heart this Christmas!



OCMC would like to thank St. Margaret's Episcopal School for its gracious support of the Thanksgiving Tournament.



If you have any questions about participating in this event or if you are a high school student interested in volunteering for the event, please contact Natalie Yee at This email address is being protected from spambots. You need JavaScript enabled to view it.. Thank you for your interest!
