We will be starting off the new quarter with some algebra activities.

Handouts: Handout | Solutions

We will discuss board-tiling problems-- is it possible to completely cover a region with a particular set of tiles without overlap? -- and interesting mathematical problems that arise from these puzzles.

Handouts: Handout

We will continue to expand on last week's topic of tilings.

Handouts: Handout | Solutions

We will be working with some algebra problems this week.

Handouts: Handout | Solutions

Continuing our work in algebra last week, we will look at remainders and divisibility.

Handouts: Solutions | Handout

We will continue our work in algebra with GCDs.

Handouts: Handout | Solutions

The Euclidean Algorithm is a way to find the greatest common divisor of two numbers. Using what we've learned in algebra in the past weeks, we will investigate how this method works.

Handouts: Handout | Solutions

Some more fun with algebra, primes, and GCDs!

Handouts: Handout | Solutions

We will finish out the quarter with some friendly competition!


Welcome back to Math Circle! We will kick off the quarter with some applications of graphs and geometry.


More work with graphs and geometry.
