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, geometry, and group theory.

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.

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, Catalan numbers, recursion, and pigeonhole principle. Recommended background: high school algebra. (Grade school 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 2014 ARML Competition throughout the year. In June 2013 thirty-five students from twenty different schools represented Colorado at the national competition. Colorado placed 23rd in the U.S., out of 139 regional teams. 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.
