Let's solve this fun math coloring worksheet step by step.

Step 1: Understand the Task


- Solve each addition and subtraction problem in the image.
- Write the answer for each problem.
- Use the color key at the bottom to determine which color to use for each answer.
- Then, color the corresponding sections of the dragon picture.

Step 2: Color Key


Here’s the color code:
- RED → 1, 7
- BLUE → 4, 8
- GREEN → 6, 9
- ORANGE → 5, 10
- YELLOW → 2, 5

> Note: There's a typo in the key — YELLOW says "2, 5", but ORANGE also includes "5". So likely, YELLOW should be 2, and ORANGE is 5, 10. But since it's written as:
>
> - YELLOW → 2, 5
> - ORANGE → 5, 10
>
> That means 5 appears in both. This could be a mistake. But let's assume:
> - YELLOW: 2 only (maybe "5" is a typo)
> - ORANGE: 5, 10
> - RED: 1, 7
> - BLUE: 4, 8
> - GREEN: 6, 9
>
> But wait — YELLOW says "2, 5", so perhaps 5 can be either yellow or orange? That’s ambiguous.

But looking closely: The key shows:
- RED → 1, 7
- BLUE → 4, 8
- GREEN → 6, 9
- ORANGE → 5, 10
- YELLOW → 2, 5

So 5 appears in both ORANGE and YELLOW — that's inconsistent. Likely, YELLOW should be 2 only, and ORANGE is 5, 10. Or maybe YELLOW is 2, and ORANGE is 5, 10, and 5 is shared? That doesn’t make sense.

But perhaps the intention is:
- YELLOW: answers that are 2 or 5
- ORANGE: answers that are 5 or 10

That would mean 5 gets colored both yellow and orange? That’s not possible.

Wait — probably a typo. Let’s assume:
- YELLOW: 2
- ORANGE: 5, 10
- RED: 1, 7
- BLUE: 4, 8
- GREEN: 6, 9

But the key says YELLOW → 2, 5, so maybe 5 is yellow, and 10 is orange.

So let’s go with:
- RED: 1, 7
- BLUE: 4, 8
- GREEN: 6, 9
- ORANGE: 10
- YELLOW: 2, 5

Yes — that makes more sense. Probably ORANGE was meant to be 10 only, and YELLOW is 2 and 5.

But the key says:
> ORANGE → 5, 10
> YELLOW → 2, 5

So 5 is in both. That’s confusing.

Wait — maybe it's a mistake, and ORANGE should be 10, and YELLOW is 2, 5.

But let's just proceed carefully.

We'll solve all problems first, then assign colors based on the numbers.

Step 3: Solve Each Problem



Let’s list all the problems and their answers:

1. 3 - 1 = → 2
2. 6 + 4 = → 10
3. 10 - 5 = → 5
4. 8 - 2 = → 6
5. 6 + 1 = → 7
6. 5 - 1 = → 4
7. 10 - 3 = → 7
8. 2 + 4 = → 6
9. 9 - 3 = → 6
10. 4 + 3 = → 7
11. 7 - 1 = → 6
12. 1 + 3 = → 4
13. 5 + 2 = → 7
14. 6 + 4 = → 10
15. 10 - 0 = → 10
16. 4 + 2 = → 6
17. 3 + 5 = → 8
18. 2 + 3 = → 5
19. 9 + 0 = → 9
20. 1 - 0 = → 1
21. 8 + 0 = → 8
22. 5 + 2 = → 7
23. 10 - 3 = → 7
24. 6 - 4 = → 2
25. 6 + 4 = → 10
26. 10 - 0 = → 10
27. 5 + 2 = → 7
28. 4 + 3 = → 7
29. 10 - 3 = → 7
30. 2 + 4 = → 6
31. 3 + 5 = → 8
32. 2 + 3 = → 5
33. 9 + 0 = → 9
34. 1 - 0 = → 1

Wait — some are repeated. Let’s list them uniquely from the image:

From the image:

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

Now, collect all unique answers and their frequencies:

| Answer | Count |
|--------|-------|
| 1 | 2 |
| 2 | 2 |
| 4 | 2 |
| 5 | 3 |
| 6 | 6 |
| 7 | 7 |
| 8 | 2 |
| 9 | 2 |
| 10 | 4 |

Now apply the color key:

Color Assignment Based on Answers



Use the key:
- RED → 1, 7
- BLUE → 4, 8
- GREEN → 6, 9
- ORANGE → 5, 10
- YELLOW → 2, 5

But now we see:
- 5 appears in both ORANGE and YELLOW — conflict!

Likely, YELLOW should be 2 only, and ORANGE is 5, 10.

But the key says YELLOW → 2, 5, so perhaps:
- 5 is colored YELLOW
- 10 is colored ORANGE

And 5 is only in one color — so maybe the key intends:
- YELLOW: 2, 5
- ORANGE: 10
- RED: 1, 7
- BLUE: 4, 8
- GREEN: 6, 9

Then:
- 1 → RED
- 2 → YELLOW
- 4 → BLUE
- 5 → YELLOW
- 6 → GREEN
- 7 → RED
- 8 → BLUE
- 9 → GREEN
- 10 → ORANGE

This avoids overlap.

So final color mapping:

| Answer | Color |
|--------|----------|
| 1 | RED |
| 2 | YELLOW |
| 4 | BLUE |
| 5 | YELLOW |
| 6 | GREEN |
| 7 | RED |
| 8 | BLUE |
| 9 | GREEN |
| 10 | ORANGE |

Step 4: Assign Colors to Each Section



Now, go through each problem and color accordingly:

1. 3 - 1 = 2YELLOW
2. 6 + 4 = 10ORANGE
3. 10 - 5 = 5YELLOW
4. 8 - 2 = 6GREEN
5. 6 + 1 = 7RED
6. 5 - 1 = 4BLUE
7. 10 - 3 = 7RED
8. 2 + 4 = 6GREEN
9. 9 - 3 = 6GREEN
10. 4 + 3 = 7RED
11. 7 - 1 = 6GREEN
12. 1 + 3 = 4BLUE
13. 5 + 2 = 7RED
14. 6 + 4 = 10ORANGE
15. 10 - 0 = 10ORANGE
16. 4 + 2 = 6GREEN
17. 3 + 5 = 8BLUE
18. 2 + 3 = 5YELLOW
19. 9 + 0 = 9GREEN
20. 1 - 0 = 1RED
21. 8 + 0 = 8BLUE
22. 5 + 2 = 7RED
23. 10 - 3 = 7RED
24. 6 - 4 = 2YELLOW
25. 6 + 4 = 10ORANGE
26. 10 - 0 = 10ORANGE
27. 5 + 2 = 7RED
28. 4 + 3 = 7RED
29. 10 - 3 = 7RED
30. 2 + 4 = 6GREEN
31. 3 + 5 = 8BLUE
32. 2 + 3 = 5YELLOW
33. 9 + 0 = 9GREEN
34. 1 - 0 = 1RED

---

Final Coloring Instructions



Now, when you color the dragon:

- Any section with answer = 1 or 7RED
- Any section with answer = 4 or 8BLUE
- Any section with answer = 6 or 9GREEN
- Any section with answer = 5YELLOW
- Any section with answer = 10ORANGE

Note: Since 5 is in YELLOW, and 10 in ORANGE, no conflict.
