The Colorado ARML A Team placed 20th overall at the 2012 ARML Competition. This year 140 fifteen-member regional teams from around the country participated. Team A's Relay Round score was the 10th highest in the country.
The CU-Boulder Outreach Committee has awarded the Colorado Math Circle $6900 for the 2012–2013 academic year. We greatly appreciate the generous financial support we have received from the Outreach Committee and Department of Applied Mathematics these past few years.

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.

Check our calendar for the 2012–13 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 2013 ARML Competition throughout the year. In June 2012 thirty-two students from eighteen different schools represented Colorado at the national competition. Colorado placed 20th in the U.S., out of 140 regional teams. In 2006 the Colorado ARML Team won first place in the B Division, outscoring over 80 teams from around the country and abroad.

Each year the math circle hosts weeklong summer workshops, including Sophie Math for girls.

There is no fee for participating in the Colorado Math Circle. We are supported by the CU-Boulder Outreach Committee and the Department of Applied Mathematics, as well as the Rocky Mountain Section of the Mathematical Association of America (MAA). Special thanks to Dr. Anne Dougherty for sponsoring our math circle.
