It looks like you've uploaded a
5x5 grid of addition problems, with one cell labeled "Free" in the center. This appears to be a
math bingo card, where each cell contains an addition expression.
Let's solve each addition problem and explain the pattern or purpose of this grid.
---
Step 1: Solve Each Expression
We'll go through each cell and compute the sum:
#### Row 1:
- 7 + 3 =
10
- 2 + 6 =
8
- 4 + 3 =
7
- 7 + 2 =
9
- 3 + 7 =
10
#### Row 2:
- 2 + 4 =
6
- 8 + 9 =
17
- 2 + 8 =
10
- 1 + 4 =
5
- 5 + 5 =
10
#### Row 3:
- 4 + 8 =
12
- 6 + 9 =
15
- Free (no value)
- 5 + 7 =
12
- 6 + 6 =
12
#### Row 4:
- 6 + 9 =
15
- 3 + 8 =
11
- 4 + 2 =
6
- 8 + 4 =
12
- 3 + 9 =
12
#### Row 5:
- 6 + 4 =
10
- 8 + 8 =
16
- 7 + 2 =
9
- 6 + 10 =
16
- 7 + 8 =
15

Step 2: Organize the Results
Now let’s write the results in the grid:
```
| 10 | 8 | 7 | 9 | 10 |
| 6 | 17 | 10 | 5 | 10 |
| 12 | 15 | Free | 12 | 12 |
| 15 | 11 | 6 | 12 | 12 |
| 10 | 16 | 9 | 16 | 15 |
```

Step 3: Analyze the Pattern
This is likely a
bingo card where students are given addition problems, and when a sum is called out (e.g., “10”), they mark the corresponding cell if it has that sum.
Let’s look at how many times each sum appears:
-
10: Appears 6 times (top row: 7+3, 3+7; row 2: 2+8, 5+5; row 5: 6+4; also 7+3, etc.)
- Positions: (1,1), (1,5), (2,3), (2,5), (5,1)
-
12: Appears 5 times
-
15: Appears 3 times
-
6: Appears 2 times
-
9: Appears 2 times
-
16: Appears 2 times
-
8, 11, 17, 5, 7: Appear once each
The "Free" space is typically the center of a bingo card and is automatically marked.

Final Answer & Explanation:
✔ This is a math bingo card designed for practicing addition facts.
Each cell contains an addition problem. When a sum is called (like “10”), players mark the cells that evaluate to that sum.
For example:
- If “10” is called, students mark all cells with expressions that equal 10.
- The “Free” space in the center is already marked.
This type of game helps reinforce mental math and number recognition.

Summary of All Sums:
| Sum | Count |
|-----|-------|
| 5 | 1 |
| 6 | 2 |
| 7 | 1 |
| 8 | 1 |
| 9 | 2 |
| 10 | 6 |
| 11 | 1 |
| 12 | 5 |
| 15 | 3 |
| 16 | 2 |
| 17 | 1 |
