This Instructional Activity is a part of the Lesson 4, Unit 3, Grade 8. In this activity, they will consider representations of two different proportional relationships and make comparisons between them. Arrange students in groups of 2-3. Assign to each group (or ask groups to choose) one of the three question sets. Tell groups that they will make a visual display for their responses to the questions. The display should clearly demonstrate their reasoning and use multiple representations in order to be convincing.
