Solving Problems Using Multiplicative Comparison

4.OA.A.1 Interpret a multiplication equation as a comparison, (e.g., interpret 35 = 5 x 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5). Represent verbal statements of multiplicative comparisons as multiplication equations.

 

4.OA.A.2 Multiply or divide to solve contextual problems involving multiplicative comparison and distinguish multiplicative comparison from additive comparison. For example, school A has 300 students and school B has 600 students: school B has two times as many students is multiplicative comparison; school B has 300 more students is additive comparison.

 

4.MD.A.2 Solve one- or two-step real world problems involving measurement with all four operations within a single system of measurement including problems involving simple fractions

Generation Genius - Multiplication Comparisons
In this unit students are introduced to multiplicative comparison problems. For students to develop this concept, they must be provided rich problem situations that encourage them to make sense of the relationships among the quantities involved.
