Let’s work through each part step by step.

---

Part 1: Double the dots and write the equation.

Each box has some dots on the left side. “Double the dots” means we take that number and add it to itself.

1. First box: 1 dot → double it → 1 + 1 = 2
2. Second box: 4 dots → double it → 4 + 4 = 8
3. Third box: 2 dots → double it → 2 + 2 = 4
4. Fourth box: 5 dots → double it → 5 + 5 = 10
5. Fifth box: 3 dots → double it → 3 + 3 = 6

---

Part 2: Find the answers.

Just add the numbers:

1. 3 + 2 = 5
2. 4 + 3 = 7
3. 5 + 4 = 9
4. 1 + 2 = 3
5. 7 + 1 = 8
6. 5 + 6 = 11

---

Final Answer:
1. 1 + 1 = 2
2. 4 + 4 = 8
3. 2 + 2 = 4
4. 5 + 5 = 10
5. 3 + 3 = 6
6. 3 + 2 = 5
7. 4 + 3 = 7
8. 5 + 4 = 9
