Engaging, inquiry-based lessons with low-cost materials can be easy to implement! The two educators from Connecticut selected to attend the Museum of Mathematics’s Rosenthal Prize Summer Institute will share highlights of three movement-based low-floor, high-ceiling lessons they sandboxed at the institute and have tried with elementary, middle, and high school students. From their experiences teaching these award-winning lessons, they will share lessons learned, resources to use the free lessons, and advice for creating environments that foster community and wonder.
