Overview

What is DECAGON?

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!

Location

This year, we will be hosting at two locations: Centennial High School(4300 Centennial Lane, Ellicott City, MD, 21042)and Glenelg High School(14025 Burntwoods Rd, Glenelg, MD 21737)

Lunch

Lunch is free at Glenelg! Lunch can be purchased for cash at Centennial. We will be serving cheese and pepperoni pizza.

Test Guidelines

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.

Individual Round

Competitors will pick 2 of the following categories to compete in:

  • Algebra/Number Theory
  • Geometry
  • Probability/Combinatorics

Each test will be 15 questions long. Competitors will have 50 minutes to complete each test.

Team Round

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).

  2. Team 2
  3. Team 3

Countdown Round

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).

Theme Round

The theme round is a more fun and casual round, and this year's theme will be revealed at the event.
