Concept Progressions Series: Addition & Subtraction - September 25, 2026, Oxford, MS

Computational skills are foundational to students' mathematical learning. During this session, participants will investigate the development of addition and subtraction concepts in the early grades and examine how those foundational understandings extend to adding and subtracting fractions, integers, and polynomials. Participants will explore strategies for helping students recognize connections among these operations in order to build fluency, flexibility, and number sense.
