Let's solve this "Sorting by Properties" worksheet step by step.

---

🔍 Task Overview:

We are given a list of items and asked to place each one in the correct section of a Venn diagram based on two properties:

- Round
- Smooth

The Venn diagram has:
- One circle labeled "round" (pink)
- One circle labeled "smooth" (green)
- An overlapping section where an item is both round and smooth

We need to classify each item accordingly.

🧩 Step 1: List All Items

From the image, the items are:

1. Basketball
2. Window
3. Balloon
4. Egg
5. Fork
6. Tire
7. Teeth
8. Golf ball
9. Bubble
10. Marble

🧠 Step 2: Analyze Each Item Based on Properties

We'll check for:
- Round? → Does it have a circular or spherical shape?
- Smooth? → Is its surface smooth (not rough or bumpy)?

Let’s go one by one:

| Item | Round? | Smooth? | Category |
|------------|--------|---------|----------|
| Basketball | ✔ Yes (sphere) | ✔ Yes (smooth surface) | Both (overlap) |
| Window | ✘ No (rectangular) | ✔ Yes (glass is smooth) | Only Smooth |
| Balloon | ✔ Yes (inflated = round) | ✔ Yes (soft and smooth) | Both (overlap) |
| Egg | ✔ Yes (oval/round) | ✔ Yes (smooth shell) | Both (overlap) |
| Fork | ✘ No (has tines, not round) | ✘ No (metal with ridges) | Neither |
| Tire | ✔ Yes (circular) | ✘ No (rubber with tread = rough) | Only Round |
| Teeth | ✘ No (irregular shape) | ✘ No (rough surface) | Neither |
| Golf ball | ✔ Yes (sphere) | ✘ No (dimpled = not smooth) | Only Round |
| Bubble | ✔ Yes (spherical) | ✔ Yes (thin film, smooth) | Both (overlap) |
| Marble | ✔ Yes (sphere) | ✔ Yes (polished, smooth) | Both (overlap) |

✔ Step 3: Place Items in the Venn Diagram

#### 🔵 Only Round (not smooth):
- Tire
- Golf ball

#### 🟢 Only Smooth (not round):
- Window

#### 🟡 Both Round and Smooth:
- Basketball
- Balloon
- Egg
- Bubble
- Marble

#### ✘ Neither:
- Fork
- Teeth

> Note: "Neither" goes outside both circles.

✔ Final Answer – Venn Diagram Labels:

```
[Only Round] [Both] [Only Smooth]
┌─────────────┐ ┌─────────────┐ ┌─────────────┐
│ Tire │ │ Basketball │ │ Window │
│ Golf ball │ │ Balloon │ │ │
└─────────────┘ │ Egg │ └─────────────┘
│ Bubble │
│ Marble │
└─────────────┘
(Overlap)

[Neither]
┌─────────────┐
│ Fork │
│ Teeth │
└─────────────┘
```

📝 Summary:

- Only Round: Tire, Golf ball
- Only Smooth: Window
- Both: Basketball, Balloon, Egg, Bubble, Marble
- Neither: Fork, Teeth

This classification is based on observable physical properties — shape (roundness) and surface texture (smoothness).
