October Addition Worksheet - Find the sum and color pictures with the same addends.

I'll solve this Halloween-themed addition worksheet. The task is to find the sum of each addition problem and then color the pictures that have the same addends.

Let me go through each problem systematically.

First, I'll calculate all the sums:

Pumpkins (Left Column):
- 5 + 3 = 8
- 3 + 5 = 8
- 4 + 2 = 6
- 8 + 3 = 11
- 6 + 2 = 8
- 3 + 8 = 11
- 17 + 3 = 20
- 3 + 17 = 20
- 14 + 0 = 14

Ghosts (Right Column):
- 9 + 5 = 14
- 12 + 2 = 14
- 2 + 12 = 14
- 6 + 3 = 9
- 3 + 6 = 9
- 8 + 4 = 12
- 9 + 6 = 15
- 11 + 7 = 18
- 6 + 9 = 15
- 14 + 6 = 20
- 13 + 5 = 18
- 6 + 14 = 20
- 10 + 4 = 14
- 3 + 12 = 15
- 12 + 3 = 15
- 14 + 2 = 16
- 16 + 3 = 19
- 3 + 16 = 19

Now, I need to identify which pictures have the same addends:

Looking at the problems, "same addends" means the two numbers being added are identical, regardless of order (since addition is commutative).

Let me group them by their addend pairs:

Addends (3, 5):
- Pumpkin: 5 + 3 = 8
- Pumpkin: 3 + 5 = 8

Addends (2, 4):
- Pumpkin: 4 + 2 = 6
- Ghost: 8 + 4 = 12 (different)
- Wait, let me reconsider - I need to look for identical pairs of numbers.

Actually, let me re-read the instruction: "Color the pictures with the same addends." This likely means to find pairs of problems that use the exact same two numbers (in any order).

Let me identify matching pairs:

1. 5 and 3:
- Pumpkin: 5 + 3 = 8
- Pumpkin: 3 + 5 = 8

2. 6 and 3:
- Ghost: 6 + 3 = 9
- Ghost: 3 + 6 = 9

3. 8 and 3:
- Pumpkin: 8 + 3 = 11
- Pumpkin: 3 + 8 = 11

4. 17 and 3:
- Pumpkin: 17 + 3 = 20
- Pumpkin: 3 + 17 = 20

5. 14 and 6:
- Ghost: 14 + 6 = 20
- Ghost: 6 + 14 = 20

6. 11 and 7:
- Ghost: 11 + 7 = 18
- Ghost: 13 + 5 = 18 (different addends)

Wait, let me check again for 11 and 7 - there's only one 11+7.

7. 9 and 6:
- Ghost: 9 + 6 = 15
- Ghost: 6 + 9 = 15

8. 12 and 3:
- Pumpkin: 12 + 3 = 15
- Ghost: 3 + 12 = 15

9. 16 and 3:
- Ghost: 16 + 3 = 19
- Ghost: 3 + 16 = 19

The instruction is to "color the pictures with the same addends," which means we should group together all problems that share the same pair of addends.

Solution:

The pairs of pictures that should be colored together (because they have the same addends) are:

1. Addends 3 and 5: The pumpkin with 5+3 and the pumpkin with 3+5
2. Addends 3 and 6: The ghost with 6+3 and the ghost with 3+6
3. Addends 3 and 8: The pumpkin with 8+3 and the pumpkin with 3+8
4. Addends 3 and 17: The pumpkin with 17+3 and the pumpkin with 3+17
5. Addends 6 and 14: The ghost with 14+6 and the ghost with 6+14
6. Addends 6 and 9: The ghost with 9+6 and the ghost with 6+9
7. Addends 3 and 12: The pumpkin with 12+3 and the ghost with 3+12
8. Addends 3 and 16: The ghost with 16+3 and the ghost with 3+16

Note: Some addend pairs appear across different shapes (pumpkins and ghosts), so those would be colored the same color even though they're different shapes.

This completes the solution to the worksheet.
