This Instructional Activity is a part of the Lesson 7, Unit 8, Grade 7. In this activity, students practice what they have learned about simulations by matching real-life scenarios to simulations. In the discussion, students are asked to explain their reasoning for their choices and think about other valid choices that could be made. Keep students in groups of 3. Give students 5 minutes of small-group time to take turns matching the items and discussing their reasoning, followed by whole-class discussion.
