WorksheetsAbout this worksheet
This maker writes addition sums for you: choose how big the numbers are, whether the sums need carrying, and how many sums fit on the page. Every press of New sheet gives a fresh set, and the answers print on a separate page.
Start a child with 1 digit sums in a line. Move to 2 digit sums without carrying so that the child learns to add ones to ones and tens to tens. Bring in carrying only when that is steady. Sums written one number under the other train the child to keep the columns straight, which is where most mistakes begin.
What this skill is
Addition is putting two amounts together and finding how many there are in all. On paper it rests on one idea: ones are added to ones, tens to tens, hundreds to hundreds. When a column makes ten or more, ten of them are exchanged for one of the next bigger place. That exchange is what schools call carrying, or regrouping.
A worked example
Take 368 + 257, written one under the other.
- Ones: 8 + 7 = 15. Write 5, carry 1 to the tens.
- Tens: 6 + 5 = 11, and the carried 1 makes 12. Write 2, carry 1 to the hundreds.
- Hundreds: 3 + 2 = 5, and the carried 1 makes 6.
The answer is 625. A quick check: 368 is near 370 and 257 is near 260, and 370 + 260 = 630, so 625 is sensible.
Tips for parents and teachers
- Ask the child to say the sum aloud while adding the ones column. Saying "seven and five is twelve, write two, carry one" fixes the habit.
- For carrying, let the child write the small carried 1 above the tens column every time. Skipping it is the most common cause of wrong answers.
- Ten correct sums done calmly teach more than thirty done in a hurry. Use the 12 question sheet for daily practice.
- Time one sheet a week, not every day. Speed should follow accuracy.
How to use this sheet at home and in class
- At home: one 12 question sheet a day, at the same hour, is enough. Mark it together, and let the child redo only the wrong sums on the back of the page.
- In class: print three or four different sheet numbers of the same level so that children sitting together cannot copy, and keep one answer page for yourself.
- For a child who is still counting on fingers, stay with 1 digit sums in a line until answers up to 9 + 9 come without counting. Column sums become easy only after that.
Mistakes to watch for
- Writing both digits of a column total, so 27 + 15 becomes 312. The child has not understood that the 1 of 12 is a ten. Show it with bundles of ten sticks.
- Starting from the left column. It works without carrying and fails with it, which is why it goes unnoticed for weeks. Always begin with the ones.
- Crooked columns when numbers have different lengths, such as 405 + 62. Squared paper, one digit in each square, cures it.
What to try next
- Subtraction worksheets: the same columns, worked the other way.
- Missing numbers worksheets: to see addition and subtraction as one fact.
- Indian money worksheets: addition used on prices.

Common questions
What is addition with carrying?
When the digits in a column add up to 10 or more, you write the ones digit and carry the tens digit to the next column on the left. For example, in 27 + 15 the ones make 12: write 2, carry 1.
Can I get the same sheet again?
Yes. Every sheet has a sheet number at the bottom. Use "Copy link" to save or share a link that opens the same sheet with the same sums.
