How it works: a quick refresher
The rules this worksheet practices, then one problem worked from start to finish.
| Strategy | How it works |
|---|---|
| Start at the left | Compare the ones digits first. 4.2 is greater than 3.9, because 4 is greater than 3. |
| Then the tenths | If the ones match, compare the tenths. 0.5 is greater than 0.45, because 5 tenths is more than 4 tenths. |
| Then the hundredths | If the tenths match, compare the hundredths. 0.37 is less than 0.38. |
| A missing place is zero | 0.5 is the same amount as 0.50, and 0.4 is the same amount as 0.40. |
| More digits can be smaller | 0.45 has more digits than 0.5, and 0.45 is the smaller number. |
Worked example
Compare 0.5 and 0.45.
- 1Write 0.5 as 0.50 so both numbers show hundredths.
- 2The ones digits match. The tenths digits are 5 and 4.
- 35 is more than 4, so 0.50 is greater than 0.45.
- 40.5 > 0.45.

Common questions
- Is there an answer key?
- Yes. Every worksheet has a matching answer key with each answer worked on the same grid or layout as the question. The worksheet code printed at the bottom of each page pairs a sheet with its key.
- Why is 0.5 greater than 0.45 when 45 is greater than 5?
- The digits after the decimal point are tenths and hundredths, not whole numbers. 0.5 is 5 tenths, which is 50 hundredths. 0.45 is 45 hundredths. 50 is more than 45.
- Is 0.4 equal to 0.40?
- Yes. The zero on the end of 0.40 means no extra hundredths. It does not change the size. 0.4 and 0.40 are the same amount, so the sign is =.
- How many different versions are there?
- About a million per skill. Each time you press the button the problems are generated fresh, so you can print a different version for every student, a retake, or another night of practice.
- Are the worksheets free?
- Yes. They are free to print and copy for your home or classroom, with no sign-up.
