Math Circle

Learn more about MSUB's fun Math outreach!

"It matters little who first arrives at an idea, rather what is significant is how far that idea can go"
- Sophie Germain

Math Circles across the world are a mathematical outreach activity, designed to let students, teachers and parents see and explore ideas and topics in mathematics not usually covered in the standard curriculum. Guided by professional mathematicians, we focus on creativity, collaboration, problem solving and discovery!

Monatana State University-Billings, with support from the Mathematical Association of America and the Dolciani foundation, is proud to host our own Math Circle for Students grades 4 through 8 in the Billings Area! Please let me know if you are interested in participating, or helping, or if you have any questions or comments! Email me at

Spring 2021 Schedule: (due to the pandemic, sessions are now online, please contact us for more info!)

1/20 Checkerstax! two players, red and black, sit before stacks of checkers with mixed colors. They can only lift up checkers of their own color, but when they do they can keep all the checkers above the ones they lift. The last player to move wins. Can we determine right away who the winner will be in any game? How can we adjust this game to form a new number system?
2/10 Staircases! How many different ways can you stock blocks together to form staircases? This seemingly simple question leads to deep and interesting queries about patterns and connections!
3/10 King Chicken! A chicken is a King Chicken if its pecks other chickens or pecks a chicken who pecks other chickens. What can we say about flocks and how kings may appear?
4/14 Counting Cats! What do Mountain peaks, paths, handshakes and parentheses have in common?
