Adding Integers with Color Counters

This video tutorial teaches how to add integers using color counters. It explains the concept of additive inverses and zero pairs, demonstrating how opposite numbers cancel each other out to make zero. The tutorial uses color counters, where yellow represents positive numbers and red represents negative numbers, to visually illustrate integer addition. Several examples are provided to show how to combine positive and negative integers, emphasizing the importance of identifying and canceling zero pairs to simplify calculations. Tips are given to avoid common mistakes in integer addition.
