This Instructional Activity is a part of the Lesson 7, Unit 4, Grade 7. The purpose of this activity is to help students understand that percent increase should be interpreted as a percent of the original or starting amount. Students are presented with two different methods to reason about and decide with which one they agree. As students work on the activity, look for students who agree with Clare and Priya, these students should be asked to share during the whole-class discussion. The focus of the discussion should be on why Priya's number line is the correct one and how the term percent increase affects the original or starting amount (it goes over 100%).
