2 Digit Addition Worksheets
Here are our range of two-digit Addition Worksheets with regrouping set out in columns.
Using these sheets will help your child to:
- use column addition to add up two 2-digit numbers together where regrouping of Ones into a Ten is needed;
- use column addition to add up two 2-digit numbers together where regrouping of Tens into a Hundred is needed;
- set out a 2 digit column addition;
The sheets have been split into sections so you can easily select the right level of difficulty.
- Section 1 has regrouping of ones into a ten;
- Section 2 has mixed 2 digit addition with and without regrouping within 100;
- Section 3 has regrouping of tens into a hundred;
- Section 4 has regrouping of both ones into a ten and also tens into a hundred.
Note: In First Grade, you only need to worry about Sections 1) and 2) looking at 2 digit addition within 100. You do not need to look at regrouping the Tens in to a Hundred.
How to do 2-Digit Addition
How to do 2-Digit Addition
Step 1) Add the Ones digit of both numbers together.
- Write the number of Ones below the line in the Ones place.
- If the total of the two digits is 10 or more, then regroup the 10 Ones into 1 Ten and move it into the Tens column.
We add the Ones: 7 + 5 = 12 Ones.
We regroup the 12 Ones into 1 Ten and 2 Ones.
We carry over 1 Ten and move it to the top of the Tens column.
We write a 2 under the line in the Ones place.
Step 2) Add the Tens digit of both numbers together, remember to add any Tens that were carried over.
- Write the number of Tens below the line in the Tens place.
- If the total of the two digits is 10 or more, then regroup the 10 Tens into 1 Hundred and move it into the Hundreds column.
We add the Tens, including the Ten we carried over: 3 + 2 + 1 = 6 Tens.
We write this number under the line in the Tens place.
As there are no further digits to add up, we have finished.
This gives us a final answer of 37 + 25 = 62
2 Digit Addition Worked Examples
Example 1) Work out 63 + 16.
This example does not need any regrouping.
Step 1) Add the Ones digit of both numbers together.
Adding the Ones gives us: 3 + 6 = 9 Ones.
We write this below the line in the Ones place.
Step 2) Add the Tens digit of both numbers together, remember to add any Tens that were carried over.
Adding the Tens gives us: 6 + 1 = 7 Tens.
We write this below the line in the Tens place.
As there are no further digits to add up, we have finished.
This gives us a final answer of 63 + 16 = 79
Example 2) Work out 59 + 34.
This example needs regrouping from the Ones to the Tens.
Step 1) Add the Ones digit of both numbers together.
- If the total of the two digits is 10 or more, then regroup the 10 Ones into 1 Ten and move it into the Tens column.
Adding the Ones gives us: 9 + 4 = 13 Ones = 1 Ten + 3 Ones.
We carry over the 1 Ten into the Tens column and write the 3 below the line in the Ones column..
Step 2) Add the Tens digit of both numbers together, remember to add any Tens that were carried over.
Adding the Tens gives us: 5 + 3 + 1 = 9 Tens.
We write this below the line in the Tens place.
As there are no further digits to add up, we have finished.
This gives us a final answer of 59 + 34 = 93
Example 3) Work out 74 + 62.
This example needs regrouping from the Tens to the Hundreds.
Step 1) Add the Ones digit of both numbers together.
Adding the Ones gives us: 4 + 2 = 6 Ones.
No regrouping is needed.
Step 2) Add the Tens digit of both numbers together.
If the total of the two digits is 10 or more, then regroup the 10 Tens into 1 Hundred.
Adding the Tens gives us: 7 + 6 = 13 Tens = 1 Hundred + 3 Tens.
As there are no further numbers to add up, we can simply write 1 in the Hundreds place and 3 in the Tens place.
As there are no further digits to add up, we have finished.
This gives us a final answer of 74 + 62 = 136
Example 4) Work out 87 + 28.
This example needs regrouping from the Ones to the Tens and from the Tens to the Hundreds.
Step 1) Add the Ones digit of both numbers together.
- If the total of the two digits is 10 or more, then regroup the 10 Ones into 1 Ten and move it into the Tens column.
Adding the Ones gives us: 7 + 8 = 15 Ones = 1 Ten + 5 Ones.
We carry over the 1 Ten into the Tens column and write the 5 below the line in the Ones column.
Step 2) Add the Tens digit of both numbers together, remember to add any Tens that were carried over.
If the total of the two digits is 10 or more, then regroup the 10 Tens into 1 Hundred.
Adding the Tens gives us: 8 + 2 + 1 = 11 Tens = 1 Hundred + 1 Ten.
As there are no further numbers to add up, we can simply write 1 in the Hundreds place and 1 in the Tens place.
As there are no further digits to add up, we have finished.
This gives us a final answer of 87 + 28 = 115
Example 5) Work out 32 + 26 + 47.
This example has three 2-digit numbers to add up and needs regrouping from the Ones to the Tens and from the Tens to the Hundreds.
Step 1) Add the Ones digit of both numbers together.
- If the total of the two digits is 10 or more, then regroup the 10 Ones into 1 Ten and move it into the Tens column.
Adding the Ones gives us: 2 + 6 + 7 = 15 Ones = 1 Ten + 5 Ones.
We carry over the 1 Ten into the Tens column.
Step 2) Add the Tens digit of both numbers together, remember to add any Tens that were carried over.
If the total of the two digits is 10 or more, then regroup the 10 Tens into 1 Hundred.
Adding the Tens gives us: 3 + 2 + 4 + 1 = 10 Tens = 1 Hundred + 0 Tens.
As there are no further numbers to add up, we can simply write 1 in the Hundreds place and 0 in the Tens place.
As there are no further digits to add up, we have finished.
This gives us a final answer of 32 + 26 + 47 = 105
