Exciting changes have taken place with Math Day!

After 40 years the PROBE exam was retired and replaced with the Math Day Public Lecture Series and Mathematics Fair.  These exciting new events provide the opportunity for students to experience a broader exploration and representation of what mathematics has to offer, and to showcase some of their own work. The highlight of the day is still the college-bowl-style competition which features a full, double-elimination tournament with 3-member teams from 64 schools.

With this exciting change, we encourage your participation in Colorado State University's Math Day event. Math Day is transitioning to a day of explorative, cooperative, and interactive mathematics for high school students from the State of Colorado and surrounding area. Math Day will be held on Thursday, November 1, 2018 in the Lory Student Center at Colorado State University.

The cost is $20.00 per student and registration is by recommendation of high school teachers.

Activities will include:

Math Day Public Lecture:

The Math Day Public Lecture is a new event and will feature a promient mathematician. This is an event that you won’t want to miss!

Mathematics Fair:

The Math Day mathematics fair is a new event and your participation is strongly encouraged!

Components of the fair include:

  1. A Mathematical themed puzzles and games corner: Share your favorites!
  2. A Mathematical themed section on constructions, devices, models, and art: If you or your students have something you would like to share, please bring it.
  3. A Mathematical themed poster session: Design a poster to display at the fair.

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:

  1. Mathematical Models and Art - Including multi-media, 3D printing, mechanisms, etc.
  2. Original Mathematics Research
  3. 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.

Team Competition:

  1. A college bowl-type tournament involving three-member teams from high schools around the state. A trophy is awarded to each of the small and large school winning teams.
Study materials and sample questions for the Team Competition can be found here.

Visitor parking passes are $12.00 per vehicle. Participants may include the correct amount with the registration payment. The requested number of parking passes will be mailed with the post-registration follow-up mailing. For information on Math Day contact Bryan Elder at (970) 491-7925 or by email at
