Adding and Subtracting Integers with Counters

In this video, Mr. Harvey teaches how to add and subtract integers using counters. Yellow counters represent positive numbers, while red counters represent negative numbers. The concept of zero pairs, where a positive and a negative cancel each other out, is introduced. Examples of adding and subtracting integers are provided, demonstrating how to handle different combinations of positive and negative numbers. The video concludes with a summary and tips for students to remember the key concepts.
