Worksheet for students to create a bar graph based on the number of volunteers each day of the week.

Let's solve the problem step by step based on the information provided in the worksheet.

Task:

Create a bar graph from the given data showing the number of student volunteers each day for a project. You need to:
- Write a title
- Label the axes
- Choose an appropriate scale
- Draw the bars

Given Data:

| Day | Monday | Tuesday | Wednesday | Thursday | Friday |
|-----------|--------|---------|-----------|----------|--------|
| Number of volunteers | 12 | 18 | 15 | 24 | 27 |

Step 1: Title

A good title should clearly describe what the graph is about.

✔ Title: *Number of Student Volunteers Each Day*

---

Step 2: Label the Axes

- Horizontal (x-axis): This shows the days of the week.
- Label: Day of the Week
- Tick marks: Monday, Tuesday, Wednesday, Thursday, Friday

- Vertical (y-axis): This shows the number of volunteers.
- Label: Number of Volunteers
- Since the highest number is 27, we need a scale that goes at least up to 27.

---

Step 3: Choose an Appropriate Scale

We need to decide how many units each grid line represents on the y-axis.

- The numbers range from 12 to 27, so the scale must cover 0 to at least 27.
- A reasonable interval is 3 or 5 units per line.

Let’s use scale of 3:
- Start at 0
- Then 3, 6, 9, 12, 15, 18, 21, 24, 27
- That gives us 9 intervals — perfect for a typical bar graph with about 10 rows.

✔ So, each grid line = 3 volunteers

Step 4: Draw the Bars

Now, draw a bar for each day with height corresponding to the number of volunteers:

- Monday: 12 → 12 ÷ 3 = 4 units high
- Tuesday: 18 → 18 ÷ 3 = 6 units high
- Wednesday: 15 → 15 ÷ 3 = 5 units high
- Thursday: 24 → 24 ÷ 3 = 8 units high
- Friday: 27 → 27 ÷ 3 = 9 units high

Each bar should be drawn above its respective day and reach the correct height.

Final Graph Components:

#### Title:
👉 *Number of Student Volunteers Each Day*

#### X-axis label:
👉 *Day of the Week*
With tick marks: Mon, Tue, Wed, Thu, Fri

#### Y-axis label:
👉 *Number of Volunteers*
With scale: 0, 3, 6, 9, 12, 15, 18, 21, 24, 27

#### Bars:
- Monday: 4 units tall
- Tuesday: 6 units tall
- Wednesday: 5 units tall
- Thursday: 8 units tall
- Friday: 9 units tall

✔ Summary of What to Fill In:

- Title: *Number of Student Volunteers Each Day*
- X-axis label: *Day of the Week*
- Y-axis label: *Number of Volunteers*
- Scale: 0 to 27, in increments of 3
- Bars: Draw vertical bars for each day with heights as calculated above.

📌 Tip:

Make sure all bars are the same width and have equal spacing between them.

This completes the bar graph! It clearly shows how volunteer numbers varied throughout the week, with the most volunteers on Friday and the least on Monday.
