For this last session of the Fall 2014 meetings, we explored a type of number puzzle involving labeling undirected graphs.
The Department of Mathematics at Boise State University is excited to announce we’ll be continuing the Boise Math Circle sessions during Spring 2015.
The program directors have extended invitations to Fall 2014 participants to continue, and are also recruiting new participants. If you or someone you know likes solving problems and wants to learn more about the creative side of math, please consider applying.

Please help us recruit participants by letting your students know about the program. If you’d like attendance reports for your students (e.g., for extra credit) , please send us an email. You’re of course welcome to join the sessions.
For this session, we worked on Modular Arithmetic by thinking about a circular number line arranged like a clock.
Dr. Brandy Wiegers, assistant professor of mathematics at Central Washington University, was our guest circle leader on Saturday, November 11, 2015.
Dr. Brandy introduced us to some interesting questions about covering up rectangles using simple square or rectangular tiles.
Map-making has some interesting connections to math. For example, it’s tough to draw a round earth on flat paper. Other problems can come up when one tries to highlight regions in a map using color. Our big question for this session is:
How can you color a map with only a few colors?

How much fruit is in that slice of fruit? In other words, what is the area of a polygon? If the polygon is drawn on a grid, how can you find the area by counting the grid points?
When we look at a highway, we often think of it as a straight line. Of course it is not straight—it curves with the earth. Still, if we say that the straight lines on the surface of the earth are the great circles, then we can begin to do geometry. Continue reading Spheres and geometry
Just a notice that we are not meeting Saturday, October 4, due to school district in-service days. See you next week!
We began our second session by noticing that in a perfect city grid such as (some of) Boise’s downtown and north end, there are a lot of ways to get from point A to point B. So how many are there really? Continue reading Downtown walking distances
The Sona sand drawings are part of the oral tradition of the Tchokwe people of Angola. The drawings are both art and science, and hold many interesting mathematical properties. Continue reading Sona sand drawings
