Adding 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 without carrying.
Practice that builds confidence
What this skill builds
These Class 1 maths worksheets help children practise adding a 2-digit number to a 1-digit number without regrouping. Learners work with sums such as 23 + 4, where the ones can be added directly and the tens stay the same.
The printable activities include clear addition practice using place value, horizontal and vertical formats, and child-friendly number work. They build confidence with tens, ones, addends, and sums before children move on to addition with carrying.
Adding a 2-digit number and a 1-digit number without regrouping teaches children to look carefully at place value. In examples like 41 + 7 or 52 + 3, only the ones place changes. The tens digit remains unchanged because the ones do not make 10 or more. This is an important bridge between single-digit addition and later 2-digit addition with carrying.
How the practice progresses
The worksheets move from straightforward number sentences to more structured practice where children identify tens and ones, add the ones, and write the sum. Vertical problems help them line up digits correctly, while horizontal problems encourage mental addition. Children repeatedly see that 34 + 5 means 3 tens and 4 ones, then 4 ones + 5 ones = 9 ones, so the answer is 39.
A simple parent routine
At home, ask your child to read the sum aloud first: “Twenty-three plus four.” Then ask, “Which digit is in the ones place?” Let the child add only the ones using fingers, counters, or quick mental counting. Finally, have them say the full answer and check that the tens digit has not changed. Keep the tone light and focus on accuracy before speed.
Classroom uses for teachers
Teachers can use these printables for independent maths practice, small-group reinforcement, homework, or quick revision after a place value lesson. They also work well in learning centres where children sort sums into “no carrying” examples and explain why no regrouping is needed.
Common errors to watch for
Some children add the 1-digit number to the tens digit instead of the ones digit, writing 23 + 4 as 63. Others misalign digits in vertical addition or change the tens digit unnecessarily. Encourage children to circle the ones digits before adding and to check whether the ones total is less than 10.

Helpful answers
Frequently asked questions
What does 2-digit plus 1-digit addition without regrouping mean?
It means adding a 1-digit number to a 2-digit number when the ones place does not make 10 or more. For example, 24 + 3 = 27, so no carrying is needed.
Is this worksheet collection suitable for Class 1?
Yes. The practice is designed for Class 1 children who are learning place value and simple addition with tens and ones.
How can I explain no regrouping to my child?
Tell your child to add the ones first. If the ones answer is less than 10, the tens digit stays the same. For example, in 35 + 2, add 5 + 2 to get 7, so the answer is 37.
Should children use objects while solving these sums?
Yes, counters, beads, sticks, or fingers can help at first. Once children understand that only the ones are being added, they can begin solving mentally.
What mistakes are common in this topic?
Children may add the 1-digit number to the tens digit, misplace digits in vertical sums, or try to carry even when it is not needed. Circling the ones digits can help prevent these errors.
