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:

There is no registration cancelation, or a refund offered after the registration. Math Kangaroo offers financial assistance to families in hardship; please contact [email protected] to ask for assistance and provide appropriate proof of hardship.
