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.

Congratulations to **Hongyi Chen** of Fairview HS who has been invited to attend the Mathematical Olympiad Summer Program (MOSP) for the third consecutive year, based on his performance in the 2017 USA Mathematical Olympiad (USAMO)!

Only the top 50-60 students who write the USA Mathematical Olympiad or USA Junior Mathematical Olympiad are invited to attend MOSP, the U.S. IMO training camp.

Congratulations to the math circle members who qualified for the
**2017 USA Mathematical Olympiad** (USAMO):

Hongyi Chen | Fairview HS |

Aaron Lou | Highlands Ranch HS |

Avi Swartz | Cherry Creek HS |

and **USA Junior Mathematical Olympiad** (USAJMO):

The winners of the Open Round of the **2017 NACLO (North American Computational Linguistics Olympiad)** have been announced. The contest, which took place on January 26, attracted 1500+ participants in the U.S. and Canada. Congratulations to

Hannah Zhang | Fairview HS |

Cynthia Lin | Fairview HS |

Andrea Lin | Fairview HS |

who ranked among the top 10% and advanced to the NACLO Invitational Round! Special congrats to Hannah who ranked 23rd overall!

Congratulations to **Kevin Wang** of Fairview High School who will be one of ten finalists participating in the 2017 **Who Wants to Be a Mathematician** competition! The national contest will take place in January at the Joint Mathematics Meetings in Atlanta. Good luck to Kevin!

Congratulations to the **Colorado ARML A1 Team** which just returned from the 2016 ARML competition! They placed 30th nationally out of 131 teams and 5th in the western division.

Special congratulations to **Hongyi Chen** of Fairview HS who qualified for the individual tiebreaker round and placed 12th out of almost 2000 participants from around the country!

Congratulations to **Hongyi Chen** of Fairview HS who has been named one of the top 12 winners of the 2016 USA Mathematical Olympiad! Congratulations to **Avi Swartz** of Cherry Creek HS who has been invited, along with Hongyi, to attend the Mathematical Olympiad Summer Program (MOSP)!

In 2016, 140,000 U.S. students participated in the American Mathematics Competitions (AMC) 10/12 exams which lead to the selection of the U.S. IMO (International Mathematical Olympiad) team. Only the top 50-60 students who write the USA Mathematical Olympiad or USA Junior Mathematical Olympiad are invited to attend MOSP, the U.S. IMO training camp.

The last time two Colorado students qualified for this select program was in 2008. Congrats to Hongyi and Avi!

The Colorado Math Circle has won **first place** in the **2015-2016 ARML Power Contest**! This is the first time we have won the contest after placing among the top seven teams for ten consecutive years. Congratulations to all who participated!!

The Colorado Math Circle is tied for third place after Round 1 of the **2015-2016 ARML Power Contest**. Congratulations to all participants! Round 2 of this team contest will take place in February.

Congratulations to **Casey Zhang** of Fairview High School who will be one of ten finalists participating in the 2016 **Who Wants to Be a Mathematician** competition! The national contest will take place in January at the Joint Mathematics Meetings in Seattle. Best of luck to Casey!

Congratulations to **Christine Soh** and **Andrea Lin** of Fairview High School for their excellent performance in the 2015 **Math Prize for Girls** competition! Christine placed among the top students and qualified for the Math Prize for Girls Olympiad in November. Andrea scored just below honorable mention. Congrats to both!

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.

We are fortunate to be supported by the CU-Boulder Department of Applied Mathematics, Department of Mathematics, and the Rocky Mountain Section of the Mathematical Association of America (MAA). Previous supporters of the math circle include the CU Outreach Committee.
