About these decimal addition worksheets
Adding decimals is column addition with one extra rule: line up the decimal points. Numbers with fewer decimal places can be padded with zeros (2.5 = 2.50). Choose the number of decimal places and the size of the numbers.
Settings you can change
Each sheet has 20 questions by default (from 6 to 40), a name, date and score line, and an answer key on a separate page. Best for grades 4–6 (ages 9–12).
- Decimal places: Tenths, Hundredths, Thousandths.
- Number size: Under 10, Under 100, Under 1,000.
- Layout: Column (stacked), In a line.
Teaching tips
- Fill empty places with zeros before adding.
- Estimate first by rounding to whole numbers.

New questions every time
The questions are written by rules on your device, not picked from a fixed sheet, so every tap of “New worksheet” gives a different set. Nothing is uploaded. Explore all math worksheets.
Frequently asked questions
Why add zeros?
Writing 2.5 as 2.50 keeps the columns lined up with numbers that have two decimal places, without changing the value.
Which grades are these worksheets for?
Grades 4–6 (ages 9–12), depending on the settings you choose. Switch on “Big print” for younger children.
Can I make a different decimal addition worksheet for each student?
Yes. Tap “New worksheet” for a fresh set of questions with the same settings. Each sheet has its own answer key, so you can hand out different versions.
Is it really free to print?
Yes. There’s no signup and no limit. The worksheets are generated on your device, and you can use them at home or in class.
What is the worksheet code?
Every sheet prints a short code. Typing the same code with the same settings rebuilds exactly the same questions, so you can reprint a sheet later or share the code with another teacher.
