This product is a fabulous introduction to the hard to teach operations and algebraic thinking standards. It is aligned with the 4th grade common core standards to teach students about multiplicative comparisons. It teaches students how mulitplication is a way to compare numbers. It also provides students with practice writing multiplicative comparison statements. It moves on to show students how to use bar models to solve multiplication and division word problems that involve multiplicative comparisons. A note taker is also provided that follows along with the PowerPoint. This allows students to get important notes down which still paying attention to the content of the presentation.
Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 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.
Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.1
I hope you find this resource helpful to teach this standard, and I hope your students enjoy it as well. Please remember to leave feedback!
