Unit: 4.5 Multiplicative Comparison and Measurement (Grade 4). 4.5 Multiplicative Comparison and Measurement Unit Goals Students interpret, represent, and solve multiplicative comparison problems using an understanding of the relationship between multiplication and division. They use this thinking to convert units of measure within a given system from larger to smaller units. Section A Goals Analyze, describe, and represent multiplicative comparison situations. Solve one-step and two-step problems involving multiplicative comparison. Section B Goals Convert from larger units to smaller units within a given system of measurement. Solve multi-step problems
