This is a powerpoint lesson on adding integers. The first slide introduces adding integers by giving real-world scenarios. On the 2nd slide the rules for adding integers are given. There are 18 problems (with solutions) on the 3rd slide and 16 problems using + and - signs on the last. I use these problems by calling on each student to solve the problem while giving me the rule. Or you can use white boards and have the students write the answers and hold them up for quick assessment.
