Practice that builds confidence
Place value in column addition
These Grade 1 addition worksheets help children add a 1-digit number to a 2-digit number in vertical columns without regrouping. Students practice lining up ones, adding the ones first, and keeping the tens digit unchanged when no new ten is made.
The printable activities include neatly spaced column problems, answer spaces, and mixed practice that builds accuracy before speed. They are useful once children understand tens and ones and are ready to move from objects to written addition.
This collection focuses on problems such as 34 + 5 or 62 + 7, written one number above the other. Children see that the 1-digit addend belongs in the ones column. Because these are no-regrouping questions, the ones total is 9 or less, so the tens digit stays the same.
How the practice progresses
The pages give repeated practice with the same structure: look at the columns, add the ones, then write the complete 2-digit sum. The format helps children connect mental addition with written work. They learn vocabulary such as digit, ones, tens, column, sum, and no regrouping without being distracted by carrying.
Simple parent routine
At home, ask your child to point to the ones column before solving each problem. Have them read the equation aloud, for example, “forty-two plus six.” After they write the answer, ask, “Did the tens digit need to change?” This quick check turns each problem into place-value practice, not just counting.
Classroom uses
Teachers can use these worksheets for guided practice after a place-value lesson, independent math centers, morning work, or a short review before introducing regrouping. The clear vertical layout also makes it easy to spot which students understand alignment and which students are still adding digits from left to right.
Common errors to watch for
Some children write the 1-digit number under the tens column, producing answers that are too large. Others add the tens digit and the 1-digit number, or they reverse the digits in the answer. Encourage neat writing, one digit per column, and a final reread of the completed number.

Helpful answers
Frequently asked questions
What does no regrouping mean in these addition worksheets?
No regrouping means the ones digits add to 9 or less, so children do not need to make a new ten or carry to the tens column.
Why is the 1-digit number written under the ones column?
A 1-digit number has only ones, so it should be placed under the ones digit of the 2-digit number. This helps children add by place value.
Are these worksheets suitable before teaching carrying?
Yes. They are designed to strengthen column alignment and place-value understanding before children move on to addition with regrouping.
How can I help my child check an answer?
Ask your child to add the ones again and then check whether the tens digit stayed the same. For example, in 53 + 4, 3 + 4 = 7, so the answer is 57.
What common mistake should I look for?
Watch for the 1-digit number being placed under the tens column. If that happens, have your child draw a quick tens-and-ones chart and rewrite the problem.
