Add 2 Digit Numbers In Columns With Regrouping Practice Activities
Class 2 printable maths worksheets for adding 2-digit numbers in columns with regrouping from ones to tens.
Practice that builds confidence
Building the idea of regrouping
These Class 2 maths worksheets focus on adding two 2-digit numbers in vertical columns when regrouping is needed. Children practise adding the ones first, making a ten, carrying to the tens column, and writing the final sum correctly.
The printable activities include carefully arranged column sums that build accuracy and confidence. They are useful for home practice, revision after a classroom lesson, or extra support when children are learning how place value works in addition.
In this skill, children move from simple column addition to sums where the ones total is more than 9, such as 37 + 45. They learn that 7 ones + 5 ones makes 12 ones, which is regrouped as 1 ten and 2 ones. This connects directly to place value: ones stay in the ones column, and the extra ten is carried to the tens column.
Progression in the worksheets
The practice begins with clear 2-digit column sums so children can focus on alignment and the order of steps. As they continue, they meet more combinations where the ones column requires regrouping. The format encourages them to add ones first, record the carried ten neatly, then add the tens. This repeated structure helps children see that regrouping is a logical exchange, not a trick.
A simple parent routine
At home, ask your child to read each number aloud before solving: “three tens and seven ones.” Let them circle the ones column, add it, and say whether regrouping is needed. If the ones make 10 or more, they can write the ones digit below and place the carried 1 above the tens column. After finishing, ask, “Does the answer look reasonable?” For 37 + 45, a sum around 80 makes sense.
Classroom uses
Teachers can use these pages after demonstrating column addition with base-ten blocks, place value charts, or quick board examples. They work well for independent practice, small-group reteaching, maths centres, or homework. A teacher can also project one problem and ask pupils to explain where the carried ten comes from before completing the worksheet.
Common errors to watch for
Some children add the tens first, forget to carry, place the carried 1 in the answer line, or write 12 in the ones column instead of regrouping it. Others misalign digits when copying numbers. Encourage careful column checking: tens under tens, ones under ones. Neat spacing matters because it protects the thinking.
Child-friendly strategy
Use the phrase: “Add ones, make a ten, carry it, then add tens.” Children can whisper this routine as they solve each sum. It gives them a dependable path through every 2-digit column addition problem with regrouping.

Helpful answers
Frequently asked questions
What does regrouping mean in 2-digit addition?
Regrouping means exchanging 10 ones for 1 ten. For example, if the ones column adds to 12, the child writes 2 in the ones place and carries 1 ten to the tens column.
Are these worksheets suitable for Class 2 maths practice in India?
Yes. They are written for Class 2 children practising 2-digit column addition with carrying, a common early maths skill after basic addition and place value.
Should children add the ones column or tens column first?
For this method, children should add the ones column first. This shows whether a ten must be carried before they add the tens column.
How can I help my child if they forget to carry?
Use a place value chart or draw bundles of ten. Ask the child to show how 10 ones become 1 ten, then write the carried 1 above the tens column before adding the tens.
What mistakes are common in 2-digit addition with regrouping?
Common mistakes include writing both digits of the ones total in the answer, carrying to the wrong place, forgetting the carried 1, and not lining up tens and ones correctly.
