3 Digit Plus 2 Digit Practice Activities
Printable 3-digit plus 2-digit addition worksheets that help students line up place values, regroup accurately, and build fluency.
Practice that builds confidence
What this addition skill builds
These printable math drill activities help children practise adding a 3-digit number and a 2-digit number with clear attention to ones, tens, and hundreds. Students build accuracy by setting up each problem, adding by place value, and regrouping when needed.
The worksheets include focused addition practice for numbers such as 247 + 36 or 508 + 74, giving learners repeated chances to strengthen written computation. They are useful for homework, extra practice, math centers, review packets, or quick fluency checks.
Adding a 3-digit number and a 2-digit number helps students connect place value with the standard addition algorithm. They learn that the 2-digit number must be placed under the tens and ones, not shifted into the hundreds column. This supports stronger understanding of digits, columns, sums, regrouping, and the role of zero in numbers such as 306 + 58.
How the practice progresses
The page focuses on one operation and one number structure, so children can concentrate on accuracy before speed. Problems may include sums without regrouping, regrouping from ones to tens, and regrouping from tens to hundreds. A typical example such as 364 + 29 shows both key steps: 4 + 9 creates a new ten, then the tens total may create a new hundred.
A simple parent routine
At home, ask your child to read the problem aloud, point to the ones column, and check that the 2-digit addend is aligned correctly. Have them solve two or three problems slowly, explaining where any regrouped ten goes. After the page is complete, choose one problem and verify it with an estimate: 364 + 29 is close to 360 + 30, so an answer near 390 makes sense.
Classroom uses for teachers
Teachers can use these printables for morning work, small-group intervention, independent practice, or a math center after a mini-lesson on regrouping. They also work well as a quick check to see which students need more support with column alignment, basic facts, or carrying into the hundreds place.
Common errors to watch for
The most common mistake is writing the 2-digit number under the hundreds and tens instead of the tens and ones. Some students forget to add the regrouped ten, while others carry a number but place it in the wrong column. Encourage neat vertical work, one digit per space, and a quick reasonableness check after each answer.

Repeating that short routine helps students become more confident and independent with 3-digit plus 2-digit addition.
Helpful answers
Frequently asked questions
What skill do these 3-digit plus 2-digit worksheets practise?
They focus on adding one 3-digit number and one 2-digit number using place value, vertical alignment, and regrouping when the ones or tens column totals more than 9.
Should the 2-digit number be lined up under the hundreds place?
No. The 2-digit number should be aligned under the tens and ones places. For 247 + 36, the 3 goes under the 4 and the 6 goes under the 7.
Do students need to know regrouping before using these pages?
Students should understand basic addition facts and have some exposure to regrouping. These worksheets are useful for practising and strengthening that skill in a focused way.
How can I help my child check an answer?
Have your child estimate before or after solving. For example, 508 + 74 is close to 510 + 70, so an answer near 580 is reasonable.
What mistakes are most common with this type of addition?
Students often misalign the 2-digit number, forget to add a regrouped ten, or place the carried number in the wrong column. Slower, neater column work usually helps.
