Bar graph

Introduction

Welcome to our math WebQuest on Bar graph

Bar graph is a chart that uses rectangular bars to show and compare different amounts or value. let's watch this short clip to build up our understanding on bar graph

They will work in small groups to research, design, and present their own creative bar graph project using data from daily life (e.g., favourite sports, snacks, or subjects).

Each group will produce a visual display titled “Our Data in Bars”, showing their understanding of bar graphs and their importance in everyday life.

 

Task

By the end of this WebQuest lesson, you will be able to:

  • identify a bar graph and its key parts (title, axes, labels, scale, and bars)
  • List the things needed for a bar graph 
  • Construct a bar graph for a given data

Your task is to

  • Visit some website to explore and build up understanding bar graphs
  • collect simple data from your classmate (e.g. favorite subject, favorite hobby, favorite sport)
  • construct your own colorful bar graph on a paper 
  • present your work to the class 
Process

Step 1: Explore and Learn (feel free to note down important points from the video)

Discuss with your group:

  • What makes a good bar graph?

  • What do the bars, axes, and scales show?

Step 2: Gather your data (within your classmate)

Choose your topic below that you find it interesting

  • Favorite sport
  • Favorite subject
  • Favorite hobby
  • Hours of sleep
  • Number of siblings

Create a quick class survey and collect data from at least 10 classmates and record your data in your tally table. 

 

Step 3: create your own Bar graph from your data 

Use your materials (chart paper, rulers, colored pencils, markers) 

Make sure to include:

  • A Title (e.g., Favorite Fruits of Year 7 Students)

  • X-axis (e.g., types of fruits)

  • Y-axis (e.g., number of students)

  • Labels and Scale

  • Colorful bars to represent data clearly

Tip: Use different colors for each bar to make it eye-catching and fun!

Step 4: Present your work to the class and feel free to hear from your classmates about their graph.

Conclusion

You’ve successfully learned how to collect, organize, and present data using bar graphs. You’ve also worked together as a team to turn numbers into a visual story!

Remember:

  • Bar graphs help us see patterns and comparisons easily.

  • The key parts are title, axes, labels, scale, and bars.

  • Data can be fun when you use it creatively!
