arml team 2017

Interested in broadening your mathematical knowledge and sharpening your analytical thinking? Join the Colorado Math Circle for exciting math talks and problem solving sessions hosted by the University of Colorado at Boulder. Speakers will include math professors and mathematicians from around the state. Topics are expected to include number theory, combinatorics, probability, and geometry.

The Euler Group is intended for advanced high school students. It will meet throughout the year to work on problem solving, focusing on topics outside the standard math curriculum. Past topics have included cyclotomic polynomials, knot theory, computability theory, and dynamical systems. (Note: Younger students should wait until ninth grade before attending, even if they are currently studying high school or college level math.)

The Galois Group is intended for advanced middle school students. It will meet throughout the year to work on problem solving. Past topics have included modular arithmetic, combinatorics, and the pigeonhole principle. The Galois MATHCOUNTS club will meet on Wednesday afternoons at CU-Boulder to practice contest math problems. (More details here.) Recommended background: high school algebra. (Note: Younger students should wait until sixth grade before attending, even if they are currently studying middle or high school math.)

You may attend any meeting without pre-registering but if you would like to add your name to the Colorado Math Circle mailing list, please complete this registration form.


Check our calendar for the 2016–17 meeting schedule.


Meetings will take place in the CU-Boulder Engineering Center or Duane Physics Building or Benson Earth Sciences Building. (See driving directions.) The classroom location will change from month to month so please check our calendar for the correct room number.

We will be preparing for the 2017 ARML Competition throughout the year. In June 2016 thirty-seven students from sixteen different schools represented Colorado at the national competition. Colorado placed 30th in the U.S., out of 131 regional teams. One team member placed 12th among 2000 participants in the competition. Twice the Colorado team has won national honors: placing first in the B division in 2006 and placing sixth in the B division in 2011. Three times Colorado students have ranked among the top ten individuals in the competition.
