In this lesson, you have learned about using place value. You can use it to name values, to write numbers as words, and represent numbers on grids. You can use place value to compare numbers. You have also seen place value used to plot numbers on a number line. Plotting numbers on a number line using place value makes it easy to visually compare them.
Give it a shot!

Order the numbers 652.15, 652.65, and 652.40 from least to greatest using a number line.
Consider setting up your number line like the one shown below.
A horizontal number line with the values between 652 and 653 marked by 0.1
The numbers from least to greatest are 652.15, 652.40, and 652.65.
A horizontal number line with the values between 652 and 653 marked by 0.1. The numbers 652.15, 652.40, and 652.65 are each marked with a closed circle.

| Set up a number line. |
| This was done for you in the problem. The number line should have space for all the numbers you need to plot. |
| Plot the numbers along the line. |
| The number 652.15 is between 652.1 and 652.2. The number 652.65 is between 652.6 and 652.7. The number 652.4 is a labeled point on the line.
A horizontal number line with the values between 652 and 653 marked by 0.1. The numbers 652.15, 652.40, and 652.65 are each marked with a closed circle. |
| Order the numbers from least to greatest. |
| On a number line, the values increase as you read from left to right. 652.15, 652.40, and 652.65. |
