Problem Description:

The task is to estimate the volume of each container in liters and circle the best estimate for each. The options provided are:
- Less than 1 liter
- About 1 liter
- More than 1 liter

Solution Approach:

To solve this problem, we need to use our understanding of the typical volumes associated with common containers. Here’s a breakdown of each item:

---

#### 1. A wine glass
- A standard wine glass typically holds about 250 ml (0.25 liters).
- Estimate: Less than 1 liter.

#### 2. A teapot
- A typical teapot can hold anywhere from 0.5 liters to 1.5 liters. Most teapots are designed to hold around 1 liter.
- Estimate: About 1 liter.

#### 3. A backpack
- A backpack is not a container for liquid but rather for carrying items. However, if we consider its capacity in terms of liquid, it could hold much more than 1 liter (e.g., several liters of water or other liquids).
- Estimate: More than 1 liter.

#### 4. A milk carton
- A standard milk carton often comes in sizes like 1 liter or slightly less (e.g., 900 ml).
- Estimate: About 1 liter.

#### 5. A mug
- A typical mug holds about 300 ml to 400 ml (0.3 to 0.4 liters).
- Estimate: Less than 1 liter.

#### 6. A pitcher
- A pitcher is designed to hold a significant amount of liquid, often ranging from 1 liter to 2 liters.
- Estimate: More than 1 liter.

#### 7. A juice box
- A standard juice box typically holds about 200 ml to 250 ml (0.2 to 0.25 liters).
- Estimate: Less than 1 liter.

#### 8. A fridge
- A refrigerator is not a container for liquid but rather for storing food. Its internal volume is much larger than 1 liter, often measured in cubic feet or liters for storage capacity.
- Estimate: More than 1 liter.

#### 9. Four glasses of juice
- Assuming each glass holds about 250 ml (0.25 liters), four glasses would hold 1 liter.
- Estimate: About 1 liter.

Final Answers:

Here are the estimates for each container:

1. A wine glass: Less than 1 liter
2. A teapot: About 1 liter
3. A backpack: More than 1 liter
4. A milk carton: About 1 liter
5. A mug: Less than 1 liter
6. A pitcher: More than 1 liter
7. A juice box: Less than 1 liter
8. A fridge: More than 1 liter
9. Four glasses of juice: About 1 liter
