As class sizes increase, effective classroom management is essential for maximizing learning. This 85‑minute session helps grades 5–12 math teachers build proactive, research-based systems using strategies from The Classroom Management Book by Harry and Rosemary Wong. Teachers will learn how clear procedures, organization, and expectations reduce disruptions and improve instructional time, especially in larger classes. Participants will leave with practical routines, planning tools, and a strong framework for starting the school year successfully.
