### 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 Russell Brown by email or telephone (859 257 3470) if you are interested in participating in High School Circle. The Circle will meet every other week on Sunday afternoons from 2 to 4.

#### 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. Students should have an interest in mathematics and willingness to learn new ideas. The sessions are informal and include problems to help develop the ideas needed to attack new topics.

#### How do I get started?

We will hold an organizational meeting for parents and students on Tuesday, 22 August 2017 from 7 to 8pm at the Math House, 654 Maxwelton Ct. near the campus of the University of Kentucky. If you are not able to attend this meeting, please contact Russell Brown by email (russell.brown@uky.edu) or telephone (859 257 3470) for information about the Circle.

#### When and where will the Math Circle meet?

We will meet at the Math House, 654 Maxwelton Ct, on the campus of the University of Kentucky from 2 to 4 on Sundays. The schedule is available at http://www.math.uky.edu/~circles/hscircle/schedule.html.

#### Is there a map to help find the Math House?

Visit the google map for the location of the Math House and suggestions for parking.

#### What is the cost?

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.
- We will not make assignments that must be done outside of our meetings. We will give optional reading or problem sets for interested students.
- Use a calculator.

#### Are there other math circles near Lexington?

Georgetown College offers a Math Circle for middle school students. Visit their website at http://www.georgetowncollege.edu/mathcircle/
