Registration Deadline: Friday, November 1, 2019

Teachers will use the online registration system to:

  • Register their school.
  • Enter the names of all students who will be participating.
  • Enter the number of posters you will bring to the Mathematics Fair.
  • Indicate how many three-person teams are desired.
  • Indicate if you are a large or small school.
  • Enter the number of parking passes requested.

Due to record participation last year, it is highly recommended that you register your school and students early.  Schools who register after the deadline may not be allowed to participate in the team competition.

Math Day Check-in:  Registration check in begins on Thursday, November 7th at 7:30 a.m. on the third floor of Lory Student Center outside the Grand Ballroom.  Even though your school has pre-registered, you MUST check in at our registration desk.  We will verify the names of all students that you bring and collect any registration fees due.

Paying your registration fee:  We now have two options for paying your registration fee of $20 per student and $12 per parking pass.
On November 7th at the registration table you may pay by check or credit card when you check in.  Currently we only have the option of taking your credit card payment in person on Math Day, but hope to have the ability to accept credit card payments on the registration site in the future.

To pay your full registration fee before math day you may send a check made out to Colorado State University by November 1st to the following address:

Department of Mathematics
Math Day Registration
1874 Campus Delivery
Fort Collins, CO  80523-1874

All student participants will receive an ID name tag at the registration desk that must be worn throughout the day so that students participating in the team competition can be identified.

The Math Day Public Lecture is an event that you won’t want to miss! Dr. Beth Malmskog, a 2014 alumna of the CSU mathematics PhD program, will be our key-note speaker this year.

The title of her talk is: Math vs. Gerrymandering: A case study in using math to help draw fair maps in Colorado

Abstract:  Gerrymandering is the process of manipulating the boundaries of electoral districts for political gain. This is considered by many to be deeply unfair, but it has been common practice in states across the country for more than 200 years.  Gerrymandering has become even more of an issue in recent years with the rise of powerful technologies and focused strategies. The constitution mandates that all states must draw new maps will be drawn in 2021, and people across the country are looking for ways to ensure that the new maps are fair. Math is an essential tool in this fight. This talk will introduce a mathematical perspective on gerrymandering and describe the work I am doing in Colorado with my collaborator Jeanne Clelland and a large group of students. We apply exciting new ideas from mathematics and tools created by the Metric Geometry and Gerrymandering Group and the Voting Rights Data Institute to generate hundreds of thousands of random possible districting plans for Colorado. These let us paint a picture of how likely different outcomes are for Colorado elections with these unbiased maps.  Our data and analysis provide a rich new perspective on Colorado’s political geography, and allow us to begin a conversation about how mathematics is essential to the 2021 redistricting in Colorado and the rest of the country.


Dr. Malmskog’s bio:

Mathematics Professor at Colorado College in Colorado Springs, Colorado

An active researcher in discrete mathematics, arithmetic geometry, number theory, coding theory, and cryptography.
Grew up in Wyoming.

Loves reading, writing, playing the accordion, listening to music, forcing others to listen to good music as a DJ, hiking, biking, cross country skiing, eating delicious food, spending time with various subsets of {animals, friends, family}.

Loves to share in the wonders of mathematics with all through multimedia, teaching, and outreach.

A strong supporter of adult basic education and college in prison, she co-led a Math Circle at Graterford State Correctional Institution, near Philadelphia, PA, and has taught mathematics courses in Graterford and the Colorado Youthful Offender System facility in Pueblo, CO.

The Mathematics Fair is a new event and your participation is strongly encouraged! We would like to encourage active engagement from all of our participants.

Components of the fair include:

  • A Mathematical themed puzzles and games corner.
  • A Mathematical themed section on constructions, devices, models, and art.
  • A Mathematical themed poster session.

We encourage each of you to participate in any and all of these components. In particular, please encourage your students to design a poster (individually or in groups) to be displayed.

For planning purposes, please let us know how many posters you plan to bring. Poster display boards will be provided.

Within the poster session, there will be three broad categories:

  • Mathematical Models and Art – Including multi-media, 3D printing, mechanisms, etc.
  • Original Mathematics Research
  • Mathematical Ideas, History, and Educational Innovations

Prizes will be awarded to the best posters in each category. In addition, participants will be eligible for a prize determined by random drawing.

A highlight of the day is a college bowl-style competition which features a full, double-elimination tournament with three-member teams from 64 schools competing in separate tournaments representing large and small schools.

Every school is allowed one 3-person team; however, you may request additional teams and every effort will be made to accommodate multiple teams for each school.  This is determined on a first-come, first-serve basis and will be decided after all schools have checked in at the registration table.

Information about the number of teams each school has been allowed, the name assigned to each team along with the time and place of their first competition will be posted on the two large monitors located outside the Grand Ballroom beginning at 10:30 a.m.  The typical nomenclature for naming is as follows

Best High School A, Best High School B, Best High School C

Important:  Once you know how many teams you have and BEFORE competitions begin, decide the roster for each 3-person team.  Complete the team roster card provided at the registration desk listing the name of the team, and ALL team members.  This card must accompany the team to all competitions.  Schools who make it to the finals must present this card so that team membership can be verified.

Once the competition begins these teams are set and substitutions between teams is not allowed.  Substitutions within teams is only allowed between rounds.  If a team is eliminated, ALL members of that team are out of the competition and cannot move to a different team still competing.

At 11:00 a.m. the large school competitions begin.

At 11:20 a.m. the small school competitions begin.

Large monitors displaying team competition brackets will be maintained outside the Grand Ballroom.  This allows both teachers and students to keep track of their school’s progress in the TEAM competitions.

Study materials and sample questions for the Team Competition can be found here

Lunch is on your own, as your schedule permits. Lory Student Center offers a number of dining choices. In addition there are a wide variety of choices adjacent to campus including Fuzzy Tacos, Wendy’s, Jim’s Wings, MacDonald’s, Five Guys Burgers and Fries, Pita Pit, Sonic, Bluebird Cafe, Rainbow Cafe, Pickle Barrel, Chipotle, and Noodles.

For students participating in the TEAM competition, we recommend lunch during one of the 20 minute off-periods during the early rounds of competition, as there are no off-periods for winners in the rounds after 1:00pm.

Visitor parking permits are $12.00 each. These parking permits will be available at the registration booth on the third floor of the Lory Student Center. Prior to the event, permits can be purchased through the registration process and mailed for your convenience.

A daily parking pass can also be purchased online by visiting  if that would be more convenient.
