This document describes a math lesson on multi-step word problems involving equations. It includes examples of setting up equations to represent relationships between variables in real-world scenarios involving buying beverages, saving money each week, collecting books, and the cost of rides at a fair. Students are asked to identify independent and dependent variables, create tables and graphs modeling the equations, and write sentences describing the variable relationships. The closing asks students to check a friend's work on a taxi cab cost problem, where the friend has identified the variables incorrectly.
