Adding 2 Digit Plus 1 Digit Practice Activities
Printable grade 3 worksheets for adding a 2-digit number and a 1-digit number, with place value practice, regrouping, and fluency building.
Practice that builds confidence
What this skill builds
These grade 3 addition worksheets help children add a 2-digit number and a 1-digit number accurately, including examples that do and do not require regrouping. Students practise using place value, counting on, and checking whether the ones make a new ten.
The printable activities include clear equations in horizontal and vertical formats, mixed practice, and problems that strengthen mental math. They are designed for independent work, math centers, homework, or quick skill review.
Adding a 2-digit number plus a 1-digit number looks simple, but it is an important bridge between basic facts and larger multi-digit addition. Children learn to keep the tens place steady while they combine the ones. For example, in 34 + 7, they think 4 ones plus 7 ones equals 11 ones, which becomes 1 ten and 1 one, so the answer is 41.
From counting on to place value
The worksheets support a steady progression. Some problems can be solved by counting on, such as 52 + 3. Others require regrouping, such as 68 + 5. Students see addition written across and down the page so they can connect mental strategies with column addition. Helpful vocabulary includes addend, sum, ones, tens, regroup, and make a ten.
A simple routine for parents
Choose one page and ask your child to solve the first two problems aloud. Have them circle the ones digits, add those first, and decide whether a new ten is made. After every few problems, ask, “Did the tens change? Why?” Finish by letting your child check one answer with a number line, base-ten blocks, or a quick drawing of tens and ones.
Classroom uses for teachers
Teachers can use these printables during addition review, small-group intervention, morning work, or math centers. They also work well as a quick check before moving into 2-digit plus 2-digit addition. For partner practice, one student can solve while the other explains whether regrouping was needed and how the tens digit changed.
Common errors to watch for
Many children add the 1-digit number to the tens digit instead of the ones digit, turning 43 + 6 into 103 or 49. Others forget to regroup when the ones total is 10 or more. Encourage students to line up numbers by place value, say the ones addition clearly, and check if the answer is reasonable.

Helpful answers
Frequently asked questions
What does 2-digit plus 1-digit addition mean?
It means adding a number from 10 to 99 to a single-digit number from 0 to 9, such as 46 + 8 or 72 + 5.

Yes. They are useful for grade 3 students who need fluency with smaller addition before working on larger multi-digit sums.
