This lesson on adding integers demonstrates how to visually represent positive and negative numbers using counters, and how to add different combinations of positive and negative numbers. The rule for adding numbers with different signs is to subtract their absolute values, while adding numbers with the same signs involves adding their absolute values and then adding the sign. The lesson provides examples and practice problems for students to apply the rules of adding integers.
