Simple addition problems using pumpkins to teach early math skills.

The task involves solving simple addition problems using visual representations of pumpkins. Each problem shows a number of pumpkins in two groups, and the goal is to add the numbers together.

Let's solve each problem step by step:

---

Problem 1:

- Visual Representation:
- First group: 2 pumpkins
- Second group: 3 pumpkins

- Mathematical Expression:
\( 2 + 3 = \boxed{5} \)

---

Problem 2:

- Visual Representation:
- First group: 4 pumpkins
- Second group: 2 pumpkins

- Mathematical Expression:
\( 4 + 2 = \boxed{6} \)

---

Problem 3:

- Visual Representation:
- First group: 4 pumpkins
- Second group: 3 pumpkins

- Mathematical Expression:
\( 4 + 3 = \boxed{7} \)

---

Problem 4:

- Visual Representation:
- First group: 2 pumpkins
- Second group: 2 pumpkins

- Mathematical Expression:
\( 2 + 2 = \boxed{4} \)

---

Final Answers:

1. \( 2 + 3 = \boxed{5} \)
2. \( 4 + 2 = \boxed{6} \)
3. \( 4 + 3 = \boxed{7} \)
4. \( 2 + 2 = \boxed{4} \)

Explanation:
Each problem involves counting the total number of pumpkins in both groups and adding them together. The visual representation helps make the addition intuitive, especially for younger learners. By simply combining the numbers shown, we arrive at the correct sums.

Final Answer Boxed:
\[
\boxed{5, 6, 7, 4}
\]
