Adding Integers with a Chip Board Model

The video tutorial focuses on adding integers using a chip model. It begins with an introduction to the materials needed, such as red and yellow chips and a chipboard. The instructor demonstrates basic addition with chips, explaining that yellow chips represent positive numbers and red chips represent negative numbers. The concept of zero pairs is introduced to simplify calculations. Several examples are provided, including -5 + 1, -3 + 5, -7 + 2, and a more complex problem, 2 + -4 + 5. The video encourages practicing with both chips and a number line to build confidence in adding integers.
