First-grade addition worksheet with 20 problems to be completed in under 2 minutes.

Problem Description:

The image shows a worksheet titled "Name" with a series of addition problems. The task is to solve these addition problems and explain the solution process.

Key Details from the Image:

1. The worksheet contains multiple rows of addition problems.
2. Each problem involves adding two single-digit numbers.
3. The goal is to compute the sum for each pair of numbers accurately and efficiently.

Solution Approach:

We will solve each addition problem step by step. Addition of single-digit numbers is straightforward, but we will break it down for clarity.

#### Row 1:
- 5 + 4 = 9
- 2 + 7 = 9
- 1 + 8 = 9
- 2 + 5 = 7
- 1 + 9 = 10
- 6 + 4 = 10
- 5 + 5 = 10

#### Row 2:
- 2 + 8 = 10
- 4 + 6 = 10
- 7 + 2 = 9
- 3 + 5 = 8
- 7 + 2 = 9
- 5 + 5 = 10
- 8 + 0 = 8

#### Row 3:
- 5 + 5 = 10
- 4 + 6 = 10
- 9 + 1 = 10
- 6 + 4 = 10
- 7 + 0 = 7
- 7 + 3 = 10
- 6 + 2 = 8

#### Row 4:
- 6 + 4 = 10
- 2 + 7 = 9
- 3 + 6 = 9
- 5 + 3 = 8
- 4 + 5 = 9
- 7 + 1 = 8
- 6 + 3 = 9

#### Row 5:
- 0 + 3 = 3
- 8 + 2 = 10
- 3 + 7 = 10
- 2 + 6 = 8
- 4 + 4 = 8
- 5 + 0 = 5
- 0 + 8 = 8

#### Row 6:
- 4 + 4 = 8
- 3 + 7 = 10
- 3 + 3 = 6
- 7 + 2 = 9
- 1 + 8 = 9
- 5 + 5 = 10
- 3 + 3 = 6

Final Answer:

Here are the sums for each row:

1. 9, 9, 9, 7, 10, 10, 10
2. 10, 10, 9, 8, 9, 10, 8
3. 10, 10, 10, 10, 7, 10, 8
4. 10, 9, 9, 8, 9, 8, 9
5. 3, 10, 10, 8, 8, 5, 8
6. 8, 10, 6, 9, 9, 10, 6

Explanation:

- Each addition problem was solved by simply adding the two given numbers.
- For example, in the first row:
- \( 5 + 4 = 9 \)
- \( 2 + 7 = 9 \)
- And so on.
- This process was repeated for all rows and columns.

Final Boxed Answer:

\[
\boxed{
\begin{array}{ccccccc}
9 & 9 & 9 & 7 & 10 & 10 & 10 \\
10 & 10 & 9 & 8 & 9 & 10 & 8 \\
10 & 10 & 10 & 10 & 7 & 10 & 8 \\
10 & 9 & 9 & 8 & 9 & 8 & 9 \\
3 & 10 & 10 & 8 & 8 & 5 & 8 \\
8 & 10 & 6 & 9 & 9 & 10 & 6 \\
\end{array}
}
