Basic fact fluency is the foundation for everything that follows in elementary math, yet many students stall at counting strategies or freeze under pressure on timed tests. This edWebinar equips K–3 teachers with practical, research-informed thinking strategies that move students beyond rote memorization toward genuine fluency with addition and subtraction facts.
Viewers will explore how students actually progress from counting, through derived facts, to automatic recall, and will learn to teach core strategies: doubles, near-doubles, make-ten, counting on and back, and fact families with confidence. Viewers will also discover how to assess fluency in ways that reveal student thinking rather than just speed, how to support learners stuck at counting strategies (including older students needing remediation), and how to explain this approach to parents who grew up on flash cards.
Every viewer will gain a clear roadmap of fact development and classroom-ready strategies they can use tomorrow—no math-specialist background required. This recorded edWebinar is of interest to K–3 teachers and school leaders.
