This Instructional Activity is a part of the Lesson 6, Unit 5, Grade 7. In this activity, students return to the familiar context of climbing up and down a cliff to apply what they have learned about subtracting signed numbers. They represent the change in elevation with an expression and then calculate the value of the expression. This activity does not provide a number line diagram or ask students to draw one, but some students may still choose to do so.
