The Julia Robinson Mathematics Festival is a nonprofit on a mission to inspire joy in mathematics through exploration and collaboration. We do this by engaging educators and students through festive events, supporting underserved and underrepresented communities, and creating high-quality, accessible materials. Since our first math festival at Google’s headquarters, we have supported almost 500 hosts in organizing events that engage K–12 students and their teachers. More than 40,000 people have created magical math moments across 26 states, 17 countries, and 6 continents.
