2025 Winter Math Competition on Dec 13th!
Math Competition
Thank you to everyone who participated in the INTEGIRLS DC 2025 Winter Competition! Thanks to the hard work of the INTEGIRLS DC team and our generous sponsors, we were able to host over 150 girls and non-binary people from the DC metropolitan area at our in-person event on 12/13.
It was remarkable to see the culmination of months of planning and preparation result in such a successful competition. We hope our competition was able to foster a feeling of community or belonging in every attendee, whether a first-time or seasoned competitor. We are incredibly proud of all participants for choosing to challenge themselves.
Special thank you to the Akamai Foundation, Akamai Foundation, AoPS Gaithersburg, SIG, Casio, David Morin, DE Shaw & Co., and Jane Street for sponsoring and donating prizes.
We hope to see everyone at our next competition! 🩷👩🔬🧬
