2nd Grade Math Worksheets - 2-Digit Addition With Regrouping ... - Free Printable

The worksheet provided is focused on 2-digit addition with regrouping. The task involves solving addition problems where the sum of the ones place may exceed 9, requiring you to "regroup" (carry over) a ten to the tens column.

Step-by-Step Solution:

#### Problem 1:
```
TENS ONES
5 7
+ 2 8
```
1. Add the ones place: \( 7 + 8 = 15 \). Write down 5 and carry over 1.
2. Add the tens place: \( 5 + 2 + 1 (\text{carried over}) = 8 \).
3. Final answer: 85

#### Problem 2:
```
TENS ONES
4 3
+ 7 8
```
1. Add the ones place: \( 3 + 8 = 11 \). Write down 1 and carry over 1.
2. Add the tens place: \( 4 + 7 + 1 (\text{carried over}) = 12 \).
3. Final answer: 121

#### Problem 3:
```
TENS ONES
2 5
+ 8 9
```
1. Add the ones place: \( 5 + 9 = 14 \). Write down 4 and carry over 1.
2. Add the tens place: \( 2 + 8 + 1 (\text{carried over}) = 11 \).
3. Final answer: 114

#### Problem 4:
```
TENS ONES
2 6
+ 2 4
```
1. Add the ones place: \( 6 + 4 = 10 \). Write down 0 and carry over 1.
2. Add the tens place: \( 2 + 2 + 1 (\text{carried over}) = 5 \).
3. Final answer: 50
