Test students' ability to solve five multi-step real-world word problems suitable for Grades 3–5 that integrate fractions, multi-digit multiplication, and measurement (length and area). Problems should require reading comprehension, modeling with diagrams, unit reasoning (including working with fractional units and simple conversions), multi-step computation, and clear written explanations. Provide complete solutions with step-by-step reasoning, intermediate calculations, labeled diagrams as needed, and teacher notes on strategies, common errors, and extensions. Emphasize both conceptual understanding and procedural fluency while keeping contexts age-appropriate and rigorous.
