Educational worksheet teaching students how to use a bar scale to measure distances on a map of Canada.

Problem Overview:

The task involves using a bar scale to measure distances between different locations in Canada on the provided map. The goal is to:

1. Measure the distances from your location (where you live) to four specific places in Canada.
2. Record these distances in kilometers.
3. Identify the greatest distance and circle it.
4. Identify the smallest distance and put a rectangle around it.

Steps to Solve the Problem:

#### Step 1: Understand the Bar Scale
The bar scale at the bottom of the map provides a visual representation of distances. It shows that:
- Each segment of the bar represents 250 km.
- The total length of the bar is divided into segments, with markings at 0, 250, 500, 750, and 1000 km.

#### Step 2: Measure Distances Using the Bar Scale
To measure the distance between two points on the map:
1. Use a ruler or a piece of paper to align with the bar scale.
2. Place one end of the ruler/paper at your starting point and extend it to the destination point.
3. Compare the length of the line you measured to the bar scale to determine the distance in kilometers.

#### Step 3: Identify Your Location
Since the problem does not specify where "you live," we will assume a hypothetical location for demonstration purposes. Let's assume you live in Toronto, Ontario (a common reference point).

#### Step 4: Measure Distances to Each Destination
We will measure the distances from Toronto to the following destinations:
1. Iqaluit, Nunavut
2. Victoria, British Columbia
3. St. John's, Newfoundland and Labrador
4. Ottawa, Ontario

##### Measurement Process:
- Align the ruler or paper along the straight-line path between Toronto and each destination.
- Compare the length of the measured path to the bar scale.

##### Example Measurements (Hypothetical):
1. Toronto to Iqaluit, Nunavut: Approximately 3 segments of the bar scale.
- Distance = \(3 \times 250 \, \text{km} = 750 \, \text{km}\).

2. Toronto to Victoria, British Columbia: Approximately 4 segments of the bar scale.
- Distance = \(4 \times 250 \, \text{km} = 1000 \, \text{km}\).

3. Toronto to St. John's, Newfoundland and Labrador: Approximately 3.5 segments of the bar scale.
- Distance = \(3.5 \times 250 \, \text{km} = 875 \, \text{km}\).

4. Toronto to Ottawa, Ontario: Approximately 1 segment of the bar scale.
- Distance = \(1 \times 250 \, \text{km} = 250 \, \text{km}\).

#### Step 5: Record the Distances
Fill in the chart with the measured distances:

| Where You Live | Place in Canada | Distance in km |
|----------------|----------------------------------|----------------|
| Toronto | Iqaluit, Nunavut | 750 |
| Toronto | Victoria, British Columbia | 1000 |
| Toronto | St. John's, Newfoundland and Labrador | 875 |
| Toronto | Ottawa, Ontario | 250 |

#### Step 6: Identify the Greatest and Smallest Distances
- Greatest Distance: Circle the largest value in the "Distance in km" column.
- Greatest Distance = 1000 km (Toronto to Victoria, British Columbia).

- Smallest Distance: Put a rectangle around the smallest value in the "Distance in km" column.
- Smallest Distance = 250 km (Toronto to Ottawa, Ontario).

#### Final Chart:
| Where You Live | Place in Canada | Distance in km |
|----------------|----------------------------------|----------------|
| Toronto | Iqaluit, Nunavut | 750 |
| Toronto | Victoria, British Columbia | 1000 |
| Toronto | St. John's, Newfoundland and Labrador | 875 |
| Toronto | Ottawa, Ontario | *250* |
