This Common Core number system lesson covers how to add and subtract rational numbers. The lesson includes research-based strategies and strategic questions that prepare students for Common Core assessments. In this lesson, students first rewrite subtraction to add the opposite if needed. Then, they determine which addition rule to use, apply it, and interpret the answer. In addition to the lesson, there are four pages of Independent Practice with questions modeled after the Common Core assessment items.
