Adding Integers: Techniques and Practice

Mr. Buffington teaches how to add integers without using a number line. The lesson covers the rules for adding integers with the same and different signs, provides practice problems, and applies these concepts to real-life scenarios like temperature changes. Students learn to find the sum or difference based on the signs of the integers and apply these skills to solve word problems.
