This Instructional Activity is a part of the Lesson 12, Unit 5, Grade 7. This activity builds students understanding of how negative rates can be used to model directed change. Students use their knowledge of dividing and multiplying negative numbers to answer questions involving rates. They are not expected to express these as relationships of the form y = kx in this activity, though some students might. In the second question students will also need to convert between different rates.
