Solve 75-38 Using Number Line Jumps: Step-by-Step Subtraction

To solve this subtraction problem using jumps on a number line, we will break down the steps as follows:

• Step 1: Start at $75$ on the number line.
• Step 2: Subtract the $30$ part of $38$ by moving 30 spaces back from $75$. This gets us to $45$ because $75 - 30 = 45$.
• Step 3: Subtract the remaining $8$ by moving 8 spaces back from $45$. This lands us on $37$ because $45 - 8 = 37$.

Each movement on the number line helps visualize the subtraction in stages. By splitting the subtraction of $38$ into $30 + 8$, the student appreciates each component's effect on the original number.

Therefore, the solution to the subtraction problem $75 - 38$ is $37$.
