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.

We will be preparing for the 2018 ARML Competition throughout the year. In June 2017 thirty-five students from eighteen different schools represented Colorado at the national competition. Colorado won 5th place in the B Division and ranked 22nd nationally out of 133 fifteen-member regional teams. Three times the Colorado team has won national honors: placing first in the B division in 2006, sixth in the B division in 2011, and fifth in the B division in 2017. Colorado students have ranked among the top ten individuals in the competition in three different years.
