🚀 NEW: Mental Math Foundations (Multiples of 10 & 100)Before tackling the long division algorithm, students must master the "Zero Pattern" strategy. This resource includes a dedicated warm-up section for: Dividing by Multiples of 10: (e.g., 800÷2=400)Dividing by Multiples of 100: (e.g., 3,600÷6=600)Pattern Recognition: Helping students see the relationship between basic facts and large quotients.
