Talking Points
- Understanding the Number Line: "Imagine the number line as a road that goes on forever in both directions, with 0 at the center."
- Positive and Negative Numbers: "Positive numbers are to the right of 0 on the number line, while negative numbers are to the left."
- Adding Positive and Negative Numbers: "When you add a positive number, you move to the right on the number line. When you add a negative number, you move to the left."
- Subtracting Positive and Negative Numbers: "Subtracting a positive number means moving to the left on the number line. Subtracting a negative number means moving to the right."
