Thanks for a Great Fall!


We had 3 great sessions this fall!

Our Septemeber session was run by Dr. Angela Antonou and Dr. Rita Patel.

During this Math Teachers’ Circle event, we explored new visual representations of functions and discover properties of numbers and functions using these new representations.


Our October Meeting was run by a guest leader from our Sister Circle, Brian Seguin.

IMG_7409.JPGDuring this session, we explored patterns and a Number Machine which takes in two numbers and produces a new number.


Our November Meeting was run by Dr. Amanda Harsy.


The session titled, “Voting Fairly,” was well timed with election day. During this event, we explored various voting systems. We applied and analyzed several established methods for determining the “voice” of the majority.


Participants also created and analyzed their own voting methods!

We look forward to more events this spring! Remember to RSVP for our January event!Math Circle Flyer Jan 28 2019 Xavier

RSVP for November 5 Meeting at University of St. Francis

Don’t forget to RSVP for the November 5 Meeting to be held at University of St. Francis in Tower Hall (N307 and N309).  You can register here:: http://bit.ly/MTCNov2018

Topic: “Voting Fairly” by Dr. Harsy.

Description: In this Math Teachers’ Circle Session, participants will explore voting systems. Specifically, this session will facilitate discovery and inquiry-based experiences in order for participants to apply and analyze several established methods for determining the “voice” of the majority. Finally, participants will be asked to create and analyze their own voting methods and decide which methods seem better suited to reflect the preferences of the voters.

Campus and parking information:  Directions to USF can be found here: https://www.stfrancis.edu/visitors/campusmaps/main/. You can also use the following address in your GPS: 500 Wilcox Dr. Joliet, IL 60586. A campus map can be found here: https://www.stfrancis.edu/visitors/campusmaps/main/. You may park in the Wilcox Street Lot which is near Tower Hall (the room for the event is N307 and N309, both located on the North side of the third floor of tower hall, which is the building numbered 11 and 12 on the campus map). Additional parking is available in the Recreation Center Lot.

If parking in Wilcox Street Lot, the building is directly across the street. Enter the nearest doors and walk toward the center (south side) of the building. You’ll reach a large set of stairs near the center of the building which you can take to the 3rd floor (exit to your right to travel north on the 3rd floor and you will reach N307/309; you’ll know you’re going the right direction if the rooms start with “N” instead of “S”). If you prefer an elevator, it is located just south of the stairs near a water fountain on the first floor; if you reach the cafeteria, you traveled too far.

We hope to see you there!

May Meeting of Modular Quilts and Star Polygons

During our May meeting hosted at Saint Xavier University, we discovered the mathematics of modular quilts and star polygons.

Dr. Dave Klanderman led an exploration that ties modular arithmetic to art.  We made colorful quilts based on modular 4 arithmetic using addition and multiplication tables for mod 4.

We also investigated reflection and rotational symmetries of star polygons with
Dr. Jaclyn Murawska and their connection to group theory.

February Meeting Recap


We had a blast exploring the mathematics behind the game SET.  Thanks Dr. Kristen Schreck for leading us through such a fun and enriching session and Thanks to the University of St. Francis for hosting us!


We first learned how to play the game SET and played a few rounds with the other mathematicians at our table.

We then answered some mathematical questions about the deck… how many sets are there? What is the probability of randomly choosing a set?


We then explored the geometry of SET… what do points, lines, planes, and hyperplanes look like in SET!


Thanks to all of you who came out! Out next and final meeting of the 2017-2018 school year will be on Monday, May 21st 6:00pm at Saint Xavier University. Hope to see you there! Remember to RSVP hereMath Circle Flyer May 21 2018 Xavier

Recap of January 2018 Meeting

We had a great turn out for our first Math Teachers’ Circle Meeting of 2018.  Rita Patel and Nicolette Staley presented on the mathematics of Sodoku. DSC_0486

Groups of K-12 teachers, professors, and future teachers worked together to solve some challenging Sudoku. We then discussed different problem-solving strategies one can use to approach these problems


We will continue our game theme in February at University of St. Francis in which we will talk about the mathematics behind the game SET.  Hope to see you there. Remember to RSVP at http://bit.ly/MTCFeb2018
