The Centennial National Math Honor Society is partnering this year with the Glenelg National Math Honor Society to host the new DECAGON Tournament, a continuation of the annual CHS Mu Alpha Theta Tournament! All levels of math competition experience are welcome.
The tournament is a great way for competitors to test their math skills in a fun, low-stress competition.
Students of all grades may register for free. If you plan to form a team with people you already know, please list the members of your team. If you register as an individual, we will place you on a team for the team round, so don’t worry!
We will be hosting at two locations:
Lunch is free at both locations! We will be serving cheese and pepperoni pizza.
All answers should be in simplest form. The only permitted materials are pencils and paper. Computational aids, including but not limited to calculators, rulers, protractors, and graph paper are strictly prohibited.
Check out some of our rounds from previous years to get used to the format and difficulty on our Archive Page!
Competitors will pick 2 of the following categories to compete in:
Each test will be 15 questions long. Competitors will have 50 minutes to complete each test.
Teams of up to 4 will take the team test. Competitors may form prearranged teams. Those without teammates will be put in a team. The test will be 10 questions and 30 minutes long. The team score will be calculated by adding twice the team round score to four times the average score on all tests of all members (as some teams have fewer than 4 people).
The top 4 competitors from each individual category will participate in a countdown round for that category. Competitors will compete head-to-head in this round. A problem will be displayed through a presentation, and the contestants will race to solve the problem (with pencil and paper).
The theme round is a more fun and casual round, and this year's theme will be revealed at the event.
