Decimal Bingo Worksheet (#13)

#### Directions:
- Solve the decimal addition problems.
- Mark off the answers in the grid.
- Win by getting five in a row.

#### Problems to Solve:
1. \( 1.33 + 4.78 = \)
2. \( 7.67 + 1.55 = \)
3. \( 0.22 + 0.44 = \)
4. \( 11.9 + 4.96 = \)
5. \( 20.03 + 4.6 = \)
6. \( 6.03 + 0.05 = \)
7. \( 7.909 + 5.05 = \)
8. \( 0.77 + 0.66 = \)
9. \( 22.2 + 3.03 = \)
10. \( 8.34 + 10.78 = \)

#### Solutions:
1. \( 1.33 + 4.78 = 6.11 \)
2. \( 7.67 + 1.55 = 9.22 \)
3. \( 0.22 + 0.44 = 0.66 \)
4. \( 11.9 + 4.96 = 16.86 \)
5. \( 20.03 + 4.6 = 24.63 \)
6. \( 6.03 + 0.05 = 6.08 \)
7. \( 7.909 + 5.05 = 12.959 \)
8. \( 0.77 + 0.66 = 1.43 \)
9. \( 22.2 + 3.03 = 25.23 \)
10. \( 8.34 + 10.78 = 19.12 \)

#### Marking the Answers:
After solving the problems, mark the corresponding answers in the Bingo grid. For example:
- \( 6.11 \) is already marked.
- \( 9.22 \) is already marked.
- \( 0.66 \) is already marked.
- \( 16.86 \) is already marked.
- \( 24.63 \) is already marked.
- \( 6.08 \) is not yet marked.
- \( 12.959 \) is not yet marked.
- \( 1.43 \) is already marked.
- \( 25.23 \) is already marked.
- \( 19.12 \) is already marked.

#### Winning Condition:
Mark the answers in the grid and check if you have five in a row (horizontally, vertically, or diagonally).

Subtraction Squares Worksheet (#3)

#### Directions:
- Each row, column, and diagonal must add up to the values shown.
- Fill in the rest of the grid based on the given numbers.

#### Example Grid:
```
| 3 | 11 | 6 |
---|-----|-----|-----|
11| | | |
---|-----|-----|-----|
6| | | 12 |
---|-----|-----|-----|
11 | 17 | 17 | 14 |
```

#### Solution Approach:
1. Use the given sums for rows, columns, and diagonals to fill in the missing numbers.
2. Ensure that all rows, columns, and diagonals add up correctly.

For example:
- The first row sums to 20: \( 3 + 11 + 6 = 20 \).
- The second row sums to 15: \( 11 + x + y = 15 \).
- Continue this process for all rows, columns, and diagonals.

#### Final Filled Grid:
```
| 3 | 11 | 6 |
---|-----|-----|-----|
11| 4 | 0 | 1 |
---|-----|-----|-----|
6| 5 | 4 | 12 |
---|-----|-----|-----|
11 | 17 | 17 | 14 |
```

Multiplication Squares Worksheet

#### Directions:
- Multiply each row, column, and diagonal.
- Write the product in the boxes on the sides and bottoms.

#### Example Grid:
```
| 4 | 1 | 3 |
---|-----|-----|-----|
7| | | |
---|-----|-----|-----|
6| | | |
---|-----|-----|-----|
8| | | 6 |
```

#### Solution Approach:
1. Multiply the numbers in each row, column, and diagonal.
2. Write the products in the designated boxes.

For example:
- Row 1: \( 4 \times 1 \times 3 = 12 \)
- Column 1: \( 4 \times 7 \times 6 = 168 \)
- Diagonal: \( 4 \times x \times 6 = \text{(calculate based on grid)} \)

#### Final Products:
- Row 1: \( 12 \)
- Row 2: \( 7 \times x \times x = \text{(calculate)} \)
- Row 3: \( 6 \times x \times x = \text{(calculate)} \)
- Row 4: \( 8 \times x \times 6 = \text{(calculate)} \)
- Column 1: \( 168 \)
- Column 2: \( 1 \times x \times x = \text{(calculate)} \)
- Column 3: \( 3 \times x \times 6 = \text{(calculate)} \)
- Diagonals: Calculate similarly.
