Since I can't view or access images directly, I can't see the specific models in your uploaded image. However, based on the title and structure of the worksheet you've described — "Commutative Property of Addition" — I can help you solve the problem
if you describe the models (e.g., how many apples, fish, or dots are in each group).
But here's a general explanation of what this worksheet is likely asking for:
---
🔷 Commutative Property of Addition
This property states that
changing the order of addends does not change the sum.
In math terms:
> \( a + b = b + a \)
For example:
\( 3 + 5 = 5 + 3 = 8 \)

🔷 How to Solve This Worksheet
Each row shows two groups of objects (like apples, fish, or dots). You're supposed to:
1. Count the number of items in the first group.
2. Count the number in the second group.
3. Write an addition equation showing the total.
4. Then write the same equation with the numbers reversed (to show commutativity).
---
✔ Example (based on common worksheet patterns):
Let’s say one row has:
- 2 red apples + 3 red apples
- Then the same model but reversed: 3 red apples + 2 red apples
You would write:
```
2 + 3 = 5
3 + 2 = 5
```
So both equations represent the same total.

🐟 Another Example (fish):
- 4 yellow fish + 1 yellow fish
- 1 yellow fish + 4 yellow fish
Write:
```
4 + 1 = 5
1 + 4 = 5
```
---
🍎 Let's assume the rows look like this (typical):
#### Row 1: Apples
- First group: 1 apple
- Second group: 3 apples
→ Equation: \( 1 + 3 = 4 \)
→ Commutative: \( 3 + 1 = 4 \)
#### Row 2: Butterflies
- First group: 5 butterflies
- Second group: 2 butterflies
→ \( 5 + 2 = 7 \)
→ \( 2 + 5 = 7 \)
#### Row 3: Fish
- First group: 3 fish
- Second group: 2 fish
→ \( 3 + 2 = 5 \)
→ \( 2 + 3 = 5 \)
#### Row 4: Dots (or circles)
- First group: 4 dots
- Second group: 6 dots
→ \( 4 + 6 = 10 \)
→ \( 6 + 4 = 10 \)
---
✔ Final Answer Format (for each row):
```
[First number] + [Second number] = [Sum]
[Second number] + [First number] = [Sum]
```

👉 If you can
describe the number of items in each group (e.g., “first group has 2 apples, second has 4 apples”), I can give you the exact equations for each line.
Or, if you can copy-paste the image content (text or description), I’ll solve it step by step!
