Mathematics is a hierarchical subject, the ability to learn more advanced concepts or procedures is predictable based on prior learning. In order to prepare students and ensure success with future math content, educators must ensure that fluency is achieved in what will someday become a prerequisite skill. For example, students that are fluent with whole numbers will be able to generalize and adapt that knowledge to rational numbers. This session will dig deeply into the importance of fluency, and teachers will walk away with instructional strategies to support building fluency in their classrooms.
