This learning resource focuses on mental math strategies specifically for addition and subtraction. It introduces students to three key techniques: partitioning, compensation, and levelling. Each strategy is designed to help students tackle multi-digit problems effectively while enabling them to articulate their reasoning. The document outlines specific success criteria, detailing what students should be able to achieve, such as breaking numbers into their place value parts, adjusting them to make calculations easier, and balancing subtraction problems. It includes practical exercises for each strategy, followed by a real-world scenario involving a toy store to enhance understanding and application of the concepts learned. Students will engage in calculations and reflect on which mental strategies they find most efficient for solving given problems.
