It is our pleasure to announce that the C/D Marathon Team will participate as a Charity Partner in the 2021 TCS New York City Marathon! We are delighted for the opportunity to showcase our inspiring group of math supporters who will run the world's largest marathon on Sunday, November 7, 2021.

Common Denominator, a nonprofit organization founded in 2002 stands mission-driven to bridging the math literacy divide for New York City middle schoolers in-need, by providing individualized math tutoring and mentorship. In the wake of the COVID-19 pandemic, C/D seamlessly pivoted from a brick-and-mortar program to a virtual online learning platform that continued to provide students with the stability to learn, play, express their feelings and thrive.
