Zearn is a nonprofit organization whose mission is to ensure all children love learning math. To transform students' understanding of math and their attitudes toward it, they created Zearn Math, a top-rated K-5 curriculum, a classroom model and administrative implementation tools used to create daily differentiation and engagement for all students. Zearn Math is designed so that each day, students work through engaging digital content at their own pace and learn targeted lessons with their teacher and peers. Zearn Math is built on the Universal Design for Learning (UDL) framework, a set of research-based guidelines for developing flexible learning environments that accommodate individual learning differences. Zearn Math enables individualized learning with coherent and aligned curricular materials: Independent Digital Lessons, Small Group Lessons, Whole Group Materials, and Assessments. To support districts and schools with implementation, Zearn offers School Accounts, Professional Development, and Printed Materials.
