The registration for the Math Circle Seminar at K-state for the 2023-2024 school year is now open! See the link in the first comment.

Dear friends of the Math Circle!

In March we will host one of the most popular national math competitions for students in grades 1-12. It is organized by Math Kangaroo USA, a national non-profit organization.
The competition consists of a singular round that is taken on the same date (third Thursday of March) by thousands of students all over the US. Kansas State University is registered as a public center meaning that every student residing in Kansas may register to participate in the competition at K-state.

If you are not familiar with Math Kangaroo competition, here are some of the problems that were on the exam in the past:
