Learning How to Add Numbers with
Regrouping

2. What is Addition?
• Addition is the process of finding the total or
sum by combining two or more numbers.

3. Understanding Place Value
• Place value tells us the value of a digit based
on its position in a number. In a two-digit
number, the first digit represents tens, and the
second digit represents ones.

4. What is Regrouping?
• Regrouping is when the sum of the digits in
one place value is more than 9, so you carry
over to the next place value.

5. Adding Without Regrouping
• Example: 25 + 14
• Step 1: Add the ones: 5 + 4 = 9
• Step 2: Add the tens: 2 + 1 = 3
• Answer: 39

6. Adding With Regrouping
• Example: 26 + 17
• Step 1: Add the ones: 6 + 7 = 13 (Regroup 13
into 1 ten and 3 ones)
• Step 2: Add the tens: 2 + 1 (carried) + 1 = 4
• Answer: 43

7. Let’s Practice!
• Solve these problems:
• 1. 48 + 36
• 2. 57 + 28
• 3. 69 + 24

8. Interactive Activity
• Work in pairs to solve the following problem
on the board: 34 + 28

9. Tips for Success
• • Always add the ones place first.
• • Don’t forget to carry over the number.
• • Double-check your work!

10. Review
• Today, we learned about addition with
regrouping. Remember to add the ones first,
regroup if necessary, and then add the tens.
