February 16, 2017 Recap: Cryptography

img_6012On February 16th, Dr. Sharon Robbert from Trinity Christian College led our second meeting of 2017. The topic was Cryptography and Dr. Robbert led our group on a classical Whodunit mystery. Throughout the session, we learned how to use different cryptography systems to solve clues to solve the mystery.
img_6014Some of the cryptographic elements discussed during the session included scytales, rail fence ciphers, shift ciphers, vigenere ciphers, one time pads, substitution ciphers, and more.img_5998

We ended the session with suggestions for how we can implement cryptography into our classrooms. Cryptography is a great way to engage students and connect to a variety of mathematical fields including, geometric measurement, modular arithmetic, statistics and frequency analysis, number theory and more.
img_6004Thanks Sharon for a great session! img_6009.jpg

Our next Math Circle Meeting won’t be until May 18th*6:00-8:30 pm at Lewis University. RSVP here:

See you next time!

*Due to K-12 testing schedules and spring breaks

Recap of January 19th Meeting: KenKen

In our first meeting of 2017, the Southwest Chicago Math Teachers’ Circle delved into the mathematics behind the game, Kenken, and how teachers could use it in their classrooms.

Kenken puzzles are n by n squares and like Sudoku, the solution requires that each row and column have the digits 1 through n exactly once, but in any order. What distinguishes Kenken from Sodoku is that a Kenken the board is divided into irregular boxes or “cages” which include a number with an operation like addition, subtraction, multiplication, or division. The numbers in the boxes must result in the given number in each “cage” after completing the given operation. IMG_5996.JPG


Kenken puzzles range in difficulty from very simple to extremely difficult which makes them great to use in classes with mixed abilities. Students who get hooked on these puzzles will have a fun way to practice their simple addition, subtraction, multiplication and division facts.


We enjoyed solving these problems individually and in groups and then discussed different problem-solving strategies that we used while solving these puzzles.


Join us for our next meeting on February 16th, 6-8:30 pm at Trinity Christian College.

Our topic will be Cryptography!

Remember to RSVP: and we hope to see you there!
