Grade 3 - Subtraction - Subtraction Visualized with a Number Line

In this video, we'll explore how to solve a subtraction problem using a number line, a visual tool that helps students understand the process of getting smaller as they subtract. We'll break down the number being subtracted by place value, allowing us to take away large chunks first and then smaller amounts, making the subtraction more manageable.

By using a number line, students can see exactly how much they're subtracting step by step, which helps reinforce their understanding of subtraction as a concept. We'll also briefly compare this method with the standard algorithm to show how the two approaches connect, emphasizing the importance of mastering the concept of subtraction before moving on to more traditional methods.
