Welcome to our 3 Digit Addition Worksheets page.
Here you will find a wide range of free printable Second Grade Addition Worksheets, which will help your child learn to add numbers with up to 3 digits.
This page contains a range of resources to help you learn and practice your 3-digit addition skills.
We have several worked examples so you can see how to work out different additions step-by-step.
We also have a range of worksheets suitable for different levels of ability.
Using our resources will help your child to:
Step 1) Add the Ones digit of both numbers together.
We add the Ones: 5 + 8 = 13 Ones.
We regroup the 13 Ones into 1 Ten and 3 Ones.
We carry over 1 Ten and move it to the top of the Tens column.
We write a 3 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.
We add the Tens, including the Ten we carried over: 1 + 2 + 1 = 4 Tens.
We write this number under the line in the Tens place.
Step 3) Add the Hundreds digit of both numbers together, remember to add any Hundreds that were carried over.
We add the Hundreds: 6 + 4 = 10 Hundreds.
We regroup the 10 Hundreds into 1 Thousand and 0 Hundreds.
As there are no further digits to add up, we write the 1 in the Thousands place and a 0 in the Hundreds place.
This example does not need any regrouping.
Step 1) Add the Ones digit of both numbers together.
Adding the Ones gives us: 7 + 2 = 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: 4 + 3 = 7 Tens. We write this below the line in the Tens place.
Step 3) Add the Hundreds digit of both numbers together, remember to add any Hundreds that were carried over.
Adding the Hundreds gives us: 2 + 1 = 3 Hundreds. We write this below the line in the Hundreds place.
This gives us a final answer of 247 + 132 = 379
Step 1) Add the Ones digit of both numbers together.
Adding the Ones gives us: 6 + 8 = 14 Ones = 1 Ten + 4 Ones. Write the 4 Ones below the line in the Ones place. 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.
Adding the Tens gives us: 1 + 0 + 4 = 5 Tens. We write this below the line in the Tens place
Step 3) Add the Hundreds digit of both numbers together, remember to add any Hundreds that were carried over.
Adding the Hundreds gives us: 5 + 2 = 7 Hundreds. We write this below the line in the Hundreds place.
This gives us a final answer of 506 + 248 = 754
Step 1) Add the Ones digit of both numbers together.
Adding the Ones gives us: 2 + 6 = 8 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: 8 + 7 = 15 Tens = 1 Hundred + 5 Tens. We write 5 Tens below the line in the Tens place. We carry 1 Hundred into the Hundreds column.
Step 3) Add the Hundreds digit of both numbers together, remember to add any Hundreds that were carried over.
Adding the Hundreds gives us: 1 + 4 + 1 = 6 Hundreds . We write this below the line in the Hundreds place.
This gives us a final answer of 482 + 176 = 658
Step 1) Add the Ones digit of both numbers together.
Adding the Ones gives us: 4 + 9 = 13 Ones = 1 Ten + 3 Ones. We write 3 Ones below the line in the Ones place and carry over 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.
Adding the Tens gives us: 1 + 7 + 8 = 16 Tens = 1 Hundred + 6 Tens. We write 6 Tens below the line in the Tens place. We carry 1 Hundred into the Hundreds column.
Step 3) Add the Hundreds digit of both numbers together, remember to add any Hundreds that were carried over.
Adding the Hundreds gives us: 1 + 9 + 3 = 13 Hundreds = 1 Thousand + 3 Hundreds .
We write 1 in the Thousands place and 3 in the Hundreds place.
This gives us a final answer of 974 + 389 = 1363
Step 1) Add the Ones digit of the 3 numbers together.
Adding the Ones gives us: 8 + 7 + 6 = 21 Ones = 2 Tens + 1 One. We write 1 One below the line in the Ones place and carry over 2 Tens into the Tens column.
Step 2) Add the Tens digit of the 3 numbers together, remember to add any Tens that were carried over.
Adding the Tens gives us: 2 + 2 + 5 + 8 = 17 Tens = 1 Hundred + 7 Tens. We write 7 Tens below the line in the Tens place. We carry 1 Hundred into the Hundreds column.
Step 3) Add the Hundreds digit of the 3 numbers together, remember to add any Hundreds that were carried over.
Adding the Hundreds gives us: 1 + 7 + 4 = 12 Hundreds = 1 Thousand + 2 Hundreds.
We write 1 in the Thousands place and 2 in the Hundreds place.
This gives us a final answer of 728 + 457 + 86 = 1271
