This Instructional Activity is a part of the Lesson 4, Unit 4, Grade 7. The purpose of this activity is to connect various representations of proportional relationships including images, equations, and descriptions. Students first match descriptions of a proportional relationship, involving a variable x, to tape diagrams that represent the situations. Then they create equations that describe the proportion using only variables. Finally, they apply their understanding to create their own scenarios and describe a proportional relationship, which is already represented in the form of a tape diagram. The focus of the discussion following the activity is on the numbers used to go from between significant quantities in a proportional relationship.
