Grade 3 - Subtraction - Compensation

In this video, we'll explore the "compensation" strategy, also known as "constant difference" in some math curriculums. This technique simplifies subtraction by adjusting both numbers, making the calculation easier while keeping the difference between them the same. It's a useful method to avoid the more complex steps of borrowing and regrouping. We'll see how this approach works and why it's an effective tool for solving subtraction problems more efficiently.
