Double-Digit Addition With Regrouping quiz

Learn how to add double-digit numbers step by step, including examples and practice problems. Perfect for kids learning math!

 

What Is Regrouping?

Regrouping happens when the sum in one column is more than 9.
We carry over the extra to the next column.
It’s like moving apples from a small basket (ones place) to a bigger basket (tens place).

Step-by-Step Example

Let’s solve 47 + 36 together:

  1. Add the Ones Place:The ones digits are 7 and 6. Adding them gives 13.

    We write 3 in the ones place and carry over 1 to the tens place.

  2. Add the Tens Place:The tens digits are 4 and 3. Adding them gives 7.

    Don’t forget the 1 we carried over! So, 7 + 1 = 8.

  3. Write the Answer:The ones place is 3, and the tens place is 8. The final answer is 83.

Practice Problems

  • 56 + 27 =
  • 68 + 34 =
  • 79 + 15 =

Tips for Success

  • Start with the ones place: Always add the right column first.
  • Carry over: If the sum is 10 or more, move the extra to the next column.
  • Write neatly: Keep numbers aligned to avoid mistakes.
