#### Use a number line to compare integers to determine value.

A number line is a visual representation of numbers arranged in order from least to greatest, typically displayed horizontally. It can be a useful tool for comparing the values of integers because it provides a clear visual reference for their relative positions. Here's how a number line can be used to compare integers:

1. **Positioning**: Each integer is represented by a point on the number line. For example, the integer 0 might be at the center, with positive integers extending to the right and negative integers extending to the left.

2. **Relative Distance**: The distance between two points on the number line corresponds to the difference in value between the integers they represent. For example, the distance between 5 and 3 on the number line is the same as the distance between -5 and -3.

3. **Comparison**: To compare the values of integers on a number line, you simply need to look at their positions relative to each other. Integers to the right are greater than those to the left. For example, 4 is greater than 2 because 4 is to the right of 2 on the number line.

4. **Inequality**: You can also use the number line to represent inequalities between integers. For example, if you have the inequality 5 > 3, you can represent it on the number line by placing a point representing 5 to the right of the point representing 3.

5. **Ordering**: By visually inspecting the number line, you can determine the order of integers from least to greatest or vice versa. This is particularly helpful when dealing with a sequence of integers or when comparing multiple integers at once.

Overall, a number line provides a straightforward and intuitive way to compare the values of integers and understand their relationships in terms of magnitude and order. It's a foundational tool in elementary mathematics education and remains useful in more advanced contexts as well.
