Overview

Students get the foundation for understanding multiplication and division in second grade. The first layer in building this foundation is a concrete understanding. They will use objects as counters to create equal groups. Making equal groups, drawing pictures, and using repeated addition all build a strong foundation for third grade, where students will dive right into multiplication and division.
