Practice that builds confidence
What children learn
These Grade 1 math worksheets help children add a 1-digit number to a 2-digit number when no regrouping is needed. Students practise noticing the ones place, adding the ones, and keeping the tens the same.
The printable activities include clear addition problems, place-value-friendly layouts, and practice that supports both mental math and written work. Examples stay within no-regrouping addition, such as 23 + 4 or 52 + 6, so children can build accuracy before moving on to carrying.
In this addition set, children work with a 2-digit number plus a 1-digit number where the ones do not make 10 or more. The key idea is simple but important: add the ones, then keep the tens. In 34 + 5, children combine 4 ones and 5 ones to make 9 ones, so the answer is 39.
How the practice progresses
The worksheets are designed to strengthen place value while children solve addition facts. Problems may appear in horizontal or vertical form, helping students connect mental addition with written addition. Children see that the tens digit does not change in no-regrouping problems, while the ones digit changes according to the addition fact.
A parent routine for home
Choose a short row of problems and ask your child to circle the ones digit in the 2-digit number. Have them say, for example, 42 plus 3 means 2 ones plus 3 ones. After solving, ask, Did the tens stay the same? Use small objects, ten-frames, or quick drawings of tens and ones if your child needs a visual check.
Classroom uses for teachers
Teachers can use these pages for morning work, math centers, small-group review, or independent practice after a place value lesson. They are also useful for spotting whether students understand the difference between adding to the ones place and changing the tens place. Pair a worksheet with base-ten blocks or quick partner explanations for stronger math talk.
Common errors to watch for
Some children add the 1-digit number to the tens digit instead of the ones digit, turning 31 + 4 into 71. Others may start regrouping even when it is not needed. Watch for reversed digits, skipped signs, and answers that change the tens without reason. Encourage students to check that the ones add up to 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 add up to less than 10, so no carrying is needed. For example, 43 + 5 = 48.
Why is this skill important in Grade 1?
It helps children connect addition facts with place value. They learn that the ones place changes while the tens place stays the same in no-regrouping problems.
How can I help my child if they keep changing the tens digit?
Ask them to underline the tens digit and circle the ones digit before adding. Remind them to add only the ones, then copy the tens digit into the answer.
Should children use base-ten blocks for these worksheets?
Base-ten blocks can be helpful at first. Children can build the 2-digit number with tens and ones, add more ones, and see that no new ten is formed.
When is a child ready to move on to regrouping?
A child is usually ready when they can solve these problems accurately, explain why the tens stay the same, and recognize when the ones total is less than 10.
