# Math Circle at the University of Washington

Homework is assigned at the end of every meeting. Usually, there is no time set aside during the Math Circle meetings to work on this homework. Instead, it's expected that each student work at home by himself or herself on the problems.

Each assignment consists of more challenging problems, expanding on what was covered in our meeting. It is not unexpected for a student to spend a couple hours on the content and still not fully complete the homework.

Of course, do not be discouraged if you cannot solve a problem! In fact, we expect everyone to keep a record of their work, including the approaches that turned out not to work. This will be invaluable in really understanding why a specific approach may or may not work.

The first half of the each meeting is spent going over the homework assigned at the end of the last meeting. During this time, students have the opportunity to discuss their solutions in a one-on-one environment with the volunteers.
