Exploring Adding Integers with the Same Signs

The video tutorial by Mr. Pastori introduces the concept of adding integers with the same signs. It begins with an explanation of using counters to model addition, where positive and negative counters cancel each other out to form zero pairs. The lesson progresses to modeling addition problems using counters and number lines, providing examples of adding both positive and negative integers. The tutorial concludes with a reflection on the rules of adding integers with the same signs, emphasizing that the sum of two positive numbers is positive, and the sum of two negative numbers is negative.

What happens when you add a positive one and a negative one?

• You get a positive number
