You're working on
4-Digit Addition with NO REGROUPING, which means when you add the digits in each column (ones, tens, hundreds, thousands), the sum must be
9 or less — so you never need to carry over to the next column.
Let’s solve each problem step by step.

🔹 Problem 1:
```
4 2 8 3
+ 5 1 1 2
----------
```
Add column by column from right to left:
-
Ones: 3 + 2 =
5
-
Tens: 8 + 1 =
9
-
Hundreds: 2 + 1 =
3
-
Thousands: 4 + 5 =
9

🔹 Problem 2:
```
6 1 8 0
+ 3 7 1 2
----------
```
-
Ones: 0 + 2 =
2
-
Tens: 8 + 1 =
9
-
Hundreds: 1 + 7 =
8
-
Thousands: 6 + 3 =
9

🔹 Problem 3:
```
1 0 6 3
+ 1 7 3 0
----------
```
-
Ones: 3 + 0 =
3
-
Tens: 6 + 3 =
9
-
Hundreds: 0 + 7 =
7
-
Thousands: 1 + 1 =
2

## 💡 Explanation Summary:
Since this is “NO REGROUPING”, you simply add each digit column-wise without carrying. If any column added up to 10 or more, that would require regrouping — but none of these problems do! That’s why they’re labeled “NO REGROUPING”.
This helps students focus on place value and basic addition facts without the complexity of carrying.
Great practice for foundational math skills! 🎉
Parent Tip: Review the logic above to help your child master the concept of addition without regrouping worksheet for grade 4.
