Problem Description:
The task involves solving basic addition problems for 1st-grade math facts. The image shows a grid with two rows of addition problems. Each problem consists of adding two numbers, and the results need to be filled in the corresponding boxes.
Image Breakdown:
#### First Row:
1. \( 1 + 2 \)
2. \( 4 + 4 \)
3. \( 7 + 1 \)
4. \( 8 + 2 \)
#### Second Row:
1. \( 7 + 3 \)
2. \( 8 + 1 \)
3. \( 3 + 2 \)
4. \( 5 + 5 \)
Solution Approach:
We will solve each addition problem step by step and fill in the results in the respective boxes.
---
#### First Row:
1.
\( 1 + 2 \):
- Add 1 and 2: \( 1 + 2 = 3 \)
- Result: \( 3 \)
2.
\( 4 + 4 \):
- Add 4 and 4: \( 4 + 4 = 8 \)
- Result: \( 8 \)
3.
\( 7 + 1 \):
- Add 7 and 1: \( 7 + 1 = 8 \)
- Result: \( 8 \)
4.
\( 8 + 2 \):
- Add 8 and 2: \( 8 + 2 = 10 \)
- Result: \( 10 \)
---
#### Second Row:
1.
\( 7 + 3 \):
- Add 7 and 3: \( 7 + 3 = 10 \)
- Result: \( 10 \)
2.
\( 8 + 1 \):
- Add 8 and 1: \( 8 + 1 = 9 \)
- Result: \( 9 \)
3.
\( 3 + 2 \):
- Add 3 and 2: \( 3 + 2 = 5 \)
- Result: \( 5 \)
4.
\( 5 + 5 \):
- Add 5 and 5: \( 5 + 5 = 10 \)
- Result: \( 10 \)
---
Final Answer:
Filling in the results in the respective boxes:
#### First Row:
- \( 1 + 2 = 3 \)
- \( 4 + 4 = 8 \)
- \( 7 + 1 = 8 \)
- \( 8 + 2 = 10 \)
#### Second Row:
- \( 7 + 3 = 10 \)
- \( 8 + 1 = 9 \)
- \( 3 + 2 = 5 \)
- \( 5 + 5 = 10 \)
Thus, the completed grid looks like this:
\[
\begin{array}{cccc}
1 & 4 & 7 & 8 \\
+2 & +4 & +1 & +2 \\
\hline
3 & 8 & 8 & 10 \\
\end{array}
\]
\[
\begin{array}{cccc}
7 & 8 & 3 & 5 \\
+3 & +1 & +2 & +5 \\
\hline
10 & 9 & 5 & 10 \\
\end{array}
\]
Final Boxed Answer:
\[
\boxed{3, 8, 8, 10, 10, 9, 5, 10}
\]
