This Common Core number system lesson covers how to add and subtract on a number line. 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 locate the first addend on the number line and move the distance of the second addend. Finally, they interpret the answer. In addition to the lesson, there are four pages of Independent Practice with questions modeled after the Common Core assessment items.
