Exploring Integer Operations with Changing Signs

Mr. Cassidy's lesson focuses on integer operations, specifically adding and subtracting positive and negative numbers. The lesson uses a number line as a visual aid and introduces rules for handling operations with parentheses. Students practice rewriting and solving problems using these rules, aiming for mastery before moving on.
