Central Kentucky Mathematics Circles

Exploring mathematics in a friendly, informal environment

Circle Suspended

The Math Circle has been suspended since the COVID pandemic began in March 2020. We have no plans to resume meetings for the forseeable future.

There are several Math Circles available online. One possibility is the JRMF Community Math Circle.

Central Kentucky Mathematics Circles

The Central Kentucky Mathematical Circles (CKMC) serves pre-college students in Central Kentucky by providing stimulating and engaging mathematical enrichment guided by Faculty Affiliates from throughout the Bluegrass region. Our goal is to provide students with opportunities and encouragement to become passionate and excited about mathematics. General information about math circles and their history can be found on the National Association of Math Circles website.

High School Math Circle:

The High School Math Circle welcomes all interested high school students. There are no admission requirements. Information for parents and students who are considering joining the Circle may be found at our introductory page, by contacting either of the CKMC Directors. Information for participants and the schedule is also available.

Information about the High School Math Circle

Mathematicians from central Kentucky colleges and universities have helped to organize the Central Kentucky High School Math Circle since the fall of 2009. A math circle is an enrichment program for high school students with an interest in mathematics. This program will allow students to explore mathematics beyond what is covered in the high school curriculum.

Please contact the directors if you are interested in participating in the High School Math Circle. The Circle will meet every other week on Sunday afternoons from 2 to 4.

Frequently asked questions

What is a mathematics circle?

A mathematics circle is a group of people who work together to explore new mathematics. Our mathematics circles will be focused on the interests of high school students and sessions will be led by faculty and students from local colleges and universities. Sessions are informal, fun, and consist of students and leaders working together on a series of problems. Examples of topics that we will consider are:

  • Does a game have a winner? How can we find a winning strategy?
  • Why are there only five regular polyhedra?
  • How many ways can we make change for a dollar using US coins?
  • How can we construct a regular pentagon with ruler and compass? What geometric figures can be constructed with ruler and compass? Are there more figures that can be constructed by origami (paper folding)?
  • How can we transmit messages securely over the internet?

Who should join the Central Kentucky High School Math Circle?

We welcome students in 8th through 12th grades. Our sessions are accessible to students who have some familiarity with Algebra and Geometry.

There is no fee to join the High School Math Circle. We ask participants to provide refreshments.

What are some things that we will do at our math circle?

  • Work with fellow students.
  • Look for interesting patterns, make conjectures (guesses), and try to determine when they are true.
  • Learn how to make sense of an unfamiliar problem.

What are some things we will not do at our math circle?

  • Lecture.
  • Work on homework, study for high school classes, or work problems from the AP Calculus exam.
  • We will not concentrate on preparing students for mathematics competitions.
