In this lesson, students apply what they learned about interpreting and representing multiplicative comparison situations to problems in context. The numbers students encounter here are greater, encouraging them to transition from discrete diagrams to tape diagrams that are more abstract, in which each section is labeled to represent a quantity (MP2).

Students continue to write equations, with symbols representing the unknown, and to describe the meanings of their equations in the context of the word problems. In both activities, they extend their understanding of multiplicative comparison and tape diagrams to solve a two-step problem.
