Problem 2:

"The picture below shows 3 groups of hot dogs. Does the picture show 3 × 3? Explain why or why not."

Looking at the image:
- There are 3 groups.
- Each group has 3 hot dogs (as seen in each box: 3 hot dogs per group).

So, we have:
- 3 groups
- 3 items in each group

This represents:
3 × 3 = 9

✔ So, yes, the picture does show 3 × 3.

Explanation:
Multiplication means "groups of." Here, there are 3 groups, and each group has 3 hot dogs. So, it is correctly showing 3 groups of 3, which is 3 × 3.

Problem 3:

"Draw a picture to show 4 × 2 = 8."

We need to draw 4 groups of 2 items each.

Here’s how you can draw it:

```
Group 1: 🍽️ 🍽️
Group 2: 🍽️ 🍽️
Group 3: 🍽️ 🍽️
Group 4: 🍽️ 🍽️
```

(You could use any symbol like circles, stars, dots, etc., but I used 🍽️ for fun.)

Each group has 2 items, and there are 4 groups → total = 4 × 2 = 8.

Alternatively, you could draw:
- 4 boxes, each with 2 hot dogs, or
- 4 rows with 2 dots in each row.

✔ This visually shows 4 groups of 2, which equals 8.

---

✔ Final Answers:

2. Yes, the picture shows 3 × 3 because there are 3 groups and 3 hot dogs in each group, so 3 × 3 = 9.

3. Draw 4 groups, each with 2 items (like dots, stars, or pictures). Example:

```
○ ○ ○ ○ ○ ○ ○ ○
```

This shows 4 groups of 2 = 8.
