One-Digit Addition; No Regrouping (A) Worksheet for 1st - 2nd ... - Free Printable

The image you uploaded is a math worksheet titled "Adding Without Regrouping (A)." The task involves solving addition problems where the sum of digits in each column does not exceed 9, meaning no carrying over (regrouping) is required. Below is a detailed explanation of how to solve these problems and an example solution.

---

Understanding the Task

1. No Regrouping: This means that when adding two numbers, the sum of the digits in each column (ones, tens, etc.) must be less than or equal to 9. If the sum exceeds 9, regrouping would be necessary, but this worksheet specifically avoids such cases.
2. Addition Format: Each problem consists of two single-digit numbers added together.
3. Objective: Solve each addition problem accurately without carrying over any digits.

Example Problem and Solution

Let’s take one of the problems from the worksheet as an example:

#### Problem:
```
5
+ 3
---
```

#### Solution:
1. Add the digits: \( 5 + 3 = 8 \).
2. Write the result below the line:
```
5
+ 3
---
8
```

#### Final Answer for this problem:
```
5
+ 3
---
8
```

General Steps to Solve Any Problem

1. Align the Numbers: Ensure both numbers are aligned vertically.
2. Add the Digits: Add the digits in each column.
3. Check for Regrouping: Since this is "Adding Without Regrouping," ensure the sum does not exceed 9.
4. Write the Result: Write the sum directly below the line.

Complete Worksheet Example

Here is how to solve one row of problems from the worksheet:

#### Row Example:
```
3 7 5 6 4 2 8 1 9 0
+ 2 1 3 2 5 6 1 7 0 3
----------------------------------------
```

#### Step-by-Step Solution:
1. \( 3 + 2 = 5 \)
2. \( 7 + 1 = 8 \)
3. \( 5 + 3 = 8 \)
4. \( 6 + 2 = 8 \)
5. \( 4 + 5 = 9 \)
6. \( 2 + 6 = 8 \)
7. \( 8 + 1 = 9 \)
8. \( 1 + 7 = 8 \)
9. \( 9 + 0 = 9 \)
10. \( 0 + 3 = 3 \)

#### Final Answer for the Row:
```
3 7 5 6 4 2 8 1 9 0
+ 2 1 3 2 5 6 1 7 0 3
----------------------------------------
5 8 8 8 9 8 9 8 9 3
```
