Math Hour | Math Hour Olympiad | Past Events | UW Math Circle |

Each spring, Seattle-area middle- and junior high-school students are invited to participate in the Monthly Math Hour on the University of Washington's campus. The Monthly Math Hour at the UW is a series of talks that will take place from **1-2pm on Sunday afternoons** to introduce students to the beautiful and exciting world of mathematics. The lectures are given completely **free** of charge in Savery Hall room 260.

Well-behaved parents and teachers are also welcome to attend with the permission of their children. Siblings are free to join in, too.

There will be time for questions and further discussion after the talks.

**Mathematical Tiling and Organization** (flyer) – handout, slides, video (

There are many mathematical problems that involve tiling (covering) all the squares on a chessboard (or similar board) with tiles of various sizes. We'll be talking about these problems and then taking tiling to the next level, with new shapes and sizes of tiles covering all types of surfaces. Plan to roll up your sleeves and move those tiles around.

**Math Playground** for younger siblings (grades K-5), organized by Prime Factor Math Circle, is back this year!

**Mildly Impressive Mathematical Card Tricks** (flyer) – slides, video (

In this talk, we'll look at a bunch of two-person magic tricks, centered on a common theme: how can you convey a lot of information with a small number of choices? We'll see a few examples of these tricks, and then learn a famous theorem that tells us why they work and when they don't. No slight of hand required, but you might need to do some arithmetic.

Math Hour Olympiad

We invite you to join our mailing list to be notified of future Math Hour events.

**Math Playground:** The younger siblings of Math Hour students are invited to get their share of fun at the Math Playground! The Math Playground is a series of exciting and educational math games and activities designed for elementary school students. The children will be busy with hands-on explorations, puzzles, and interesting problems and will stretch their logical thinking with mathematical games. Math Playground is designed for students in grades K-5, organized by Prime Factor Math Circle, and is held next door to the Math Hour lecture, in Savery Hall room 264.
