Add In Columns 2 Digit Plus 1 Digit No Regrouping Practice Activities
Printable Class 1 maths worksheets for adding a 2-digit number and a 1-digit number in columns without regrouping.
Practice that builds confidence
Building the idea of column addition
These Class 1 addition worksheets help children add a 2-digit number and a 1-digit number in vertical columns without regrouping. They practise reading the tens and ones places, adding only the ones, and keeping the tens digit unchanged when no carry is needed.
The printable activities include clear column sums such as 24 + 3 and 56 + 2, with space to write answers neatly. Children build confidence with place value, correct alignment, and simple addition facts before moving to sums that need regrouping.
In this set, children work with a 2-digit number plus a 1-digit number, written one below the other. The important idea is place value: the 2-digit number has tens and ones, while the 1-digit number belongs in the ones column. For example, in 34 + 5, children add 4 ones and 5 ones to make 9 ones, while the 3 tens stay the same, so the answer is 39.
No regrouping keeps the focus clear
All sums are chosen so the ones total is less than 10. This means there is no carrying to the tens column. Children can concentrate on alignment, counting on, and writing the answer in the correct place. Useful maths vocabulary includes tens, ones, digit, column, add, sum, and answer.
A simple parent routine
At home, ask your child to point to the ones column before solving each sum. Say, “Add the ones first,” then let the child count on from the larger ones digit if needed. After the answer is written, ask, “Did the tens digit change?” For a sum like 42 + 6, the child can explain: 2 + 6 = 8, so 42 becomes 48. This short talk helps them understand the method instead of only filling blanks.
Classroom uses for teachers
Teachers can use these worksheets after introducing tens and ones with bundles, sticks, beads, or place value charts. They work well for guided practice, maths centres, early finishers, homework, or quick revision before teaching regrouping. The format also helps teachers spot whether a child understands column placement or is simply adding all visible digits.
Common errors to watch for
Some children write the 1-digit addend under the tens column by mistake, turning 35 + 4 into a confusing layout. Others try to add the tens digit and the 1-digit number, or write two digits in the ones place. Encourage neat columns and a left-to-right check of the final number: tens first, then ones.

Helpful answers
Frequently asked questions
What does 2 digit plus 1 digit no regrouping mean?
It means adding a 2-digit number and a 1-digit number where the ones add up to less than 10, so children do not need to carry to the tens column.
Why should the 1-digit number be written in the ones column?
A 1-digit number has only ones, so it must line up under the ones digit of the 2-digit number. This helps children add the correct place values.
Are these worksheets suitable before teaching carrying?
Yes. They are designed for practice before regrouping, helping Class 1 children understand column layout and place value first.
How can I help my child solve these sums at home?
Ask your child to point to the ones column, add the ones digits, copy the tens digit, and then read the full answer aloud.
What mistake is most common in this topic?
Many children misalign the 1-digit number under the tens column. Remind them that the single digit belongs under the ones place.
