Sonia Kovalevsky Women in Math Day is an opportunity for high school students and their teachers to join the CSU Mathematics Department in celebrating women in mathematics! CSU’s inaugural SK Day occurred on March 12, 2020. Our first year had over 150 young women register! We explored topology, cryptography, game theory, and got to hear from inspiring mathematicians.

SK Day is an opportunity to explore modern math research, to see what possibilities math can give, and to grow the mathematical community.

We are excited to announce that we will be hosting another Sonia Kovalevsky Day on March 31, 2022! This is scheduled to be an in-person event on the CSU campus. We will be following the COVID procedures set by both CSU and any state or local guidelines. For more information about policies, see the CSU COVID page.

Registration is free for both schools and students! Registration is now closed.

More information about SK Day 2022 will be posted as we finalize our speakers and schedule!
