This Instructional Activity is a part of the Lesson 2, Unit 5, Grade 7. In this activity, the context of temperature is used to help students make sense of adding signed numbers. First students reason about temperature increases and decreases. They represent these increases and decreases on a number line, and then connect these temperature changes with adding positive numbers for increases and adding negative numbers for decreases.
