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 to build fluency, flexibility, and number sense.  There are currently six unique sessions within this professional learning series. You may register for one or more sessions.  Time: September 25, 2026  – 9:00am-4:00pm Credits Available: 0.6 CEUs Cost: $150 per session Registration Deadline: September 17, 2026    Event Details Event Type
