3 Digit Plus 2 Digit Practice Activities
Printable maths drills for practising 3-digit plus 2-digit addition using place value, column alignment, and regrouping.
Practice that builds confidence
What children practise
These 3 digit plus 2 digit practice activities help children add numbers such as 342 + 25 or 476 + 58 with increasing confidence. The focus is on place value, neat column work, and understanding how ones, tens, and hundreds combine.
The printable worksheets include addition drills that build accuracy and fluency, from simple sums without carrying to problems where children regroup ones or tens. They are useful for home revision, class practice, warm-ups, and extra maths support.
In this Mathematics > Math Drills > Addition collection, children work with a 3-digit number and a 2-digit number, usually within 100-999 plus 10-99. They learn to read each addend, line up the ones and tens correctly, add from right to left, and record the sum clearly. The key vocabulary is addend, sum, ones, tens, hundreds, carry, and regroup.
How the skill progresses
Early practice can involve sums like 214 + 32, where each place can be added without regrouping. Children then meet examples such as 368 + 47, where 8 ones + 7 ones makes 15 ones, so 1 ten is carried. Later questions may require regrouping in the tens column too, helping children see that addition is not just counting on but combining place values.
A simple parent routine
Choose one worksheet and ask your child to solve the first two sums slowly while saying the steps aloud: “ones first, then tens, then hundreds.” After that, let them complete a short set independently. Check together with a pencil of another colour, not just for the final answer but for column alignment and carried digits. If an error appears, rewrite one similar sum on rough paper and solve it side by side.
Classroom uses for teachers
Teachers can use these sheets as morning maths drills, small-group remediation, quick checks after teaching column addition, or practice at a maths centre. They also work well for mixed readiness: some pupils may need place-value blocks or expanded form, while others can focus on speed with accuracy. A finished worksheet gives useful evidence of whether mistakes come from facts, alignment, or regrouping.
Common errors to watch for
Many children write the 2-digit number under the hundreds and tens instead of under tens and ones. Others forget to add the carried 1, carry into the wrong column, or treat 0 as a blank. Encourage them to draw faint place-value columns or box the ones column before starting.

Helpful answers
Frequently asked questions
What does 3 digit plus 2 digit addition mean?
It means adding a 3-digit number to a 2-digit number, such as 245 + 36. Children must align the ones and tens correctly before adding.
Should children start from the ones column or the hundreds column?
They should start from the ones column on the right. This makes regrouping easier when the ones or tens add up to 10 or more.
Do these worksheets include carrying?
The activities support practice with both straightforward addition and sums where children may need to carry or regroup ones and tens.
How can I help if my child keeps misaligning the numbers?
Ask your child to draw three light columns labelled H, T, and O. The 2-digit number should go under the tens and ones columns, leaving the hundreds place empty.
Are these worksheets useful for maths drill practice?
Yes. They provide focused addition practice so children can build speed, accuracy, and confidence with 3-digit plus 2-digit sums.
