Lesson Plan

Global Graphs: Bar Chart Bonanza

Students will collect data related to different countries, create bar graphs to represent this data, and interpret their findings to understand global diversity.

Understanding how to represent and interpret data is a crucial skill for analyzing information from the world around us. This lesson connects math skills to real-world global issues, making learning relevant and engaging.

Audience

7th Grade Students

Time

30 minutes

Approach

Hands-on data collection, graph creation, and collaborative discussion.

Materials

Whiteboard or projector, Markers or pens, Rulers, Slide Deck: Global Graphs, and Bar Graph Worksheet: International Week

Prep

Prepare Materials

10 minutes

Step 1

Introduction & Warm-Up

5 minutes

  • Engage: Begin by asking students what they know about International Week or different countries. (2 minutes)
    * Introduce: Present the lesson objective and connect it to International Week. Explain that bar graphs are a great way to compare data across different categories, like countries! (3 minutes)
    Refer to Slide Deck: Global Graphs - Slides 1-2

Step 2

Data Collection: A World of Numbers

10 minutes

  • Brainstorm: As a class, brainstorm 3-4 countries students are interested in. (2 minutes)
    * Choose Data Points: Decide on one or two simple numerical data points about these countries that can be easily compared (e.g., number of official languages, population in millions, average annual temperature, land area in square kilometers). Keep it simple for a 30-minute lesson. (3 minutes)
    * Collect Data: As a class, quickly find or estimate these data points for each chosen country. Write them on the board. (5 minutes)
    Refer to Slide Deck: Global Graphs - Slide 3

Step 3

Bar Graph Creation

10 minutes

  • Distribute: Hand out the Bar Graph Worksheet: International Week. (1 minute)
    * Instructions: Explain to students that they will now create a bar graph using the class data collected on the board. Remind them about labeling axes, choosing appropriate scales, and drawing accurate bars. (2 minutes)
    * Individual Work: Students work independently to complete their bar graphs on the worksheet. Circulate to provide support. (7 minutes)
    Refer to Slide Deck: Global Graphs - Slide 4

Step 4

Share & Discuss

5 minutes

  • Pair Share: Have students quickly turn to a partner and explain one thing their bar graph shows about the countries. (2 minutes)
    * Class Discussion: Bring the class back together. Ask a few students to share their observations. Discuss questions like: 'Which country had the highest/lowest [data point]?' 'What does this graph tell us about these countries?' (3 minutes)
    * Wrap Up: Reiterate the importance of bar graphs for comparing data and understanding information about our world.

Global Graphs: Bar Chart Bonanza

Discover the World Through Data!

Get ready to explore different countries and show off your math skills!

Welcome students and introduce the exciting topic of creating bar graphs with a global twist for International Week! Emphasize the fun and relevance.

What's a Bar Graph?

  • Compares different categories: Perfect for comparing countries!
  • Uses bars to show data: Taller bar = more of something!
  • Helps us see patterns and differences: Quick visual insights!

Explain what a bar graph is (a way to compare different categories using bars) and why it's a great tool for comparing information about countries, especially for International Week.

Our World, Our Data!

Let's pick a few countries and some fun facts to compare!

Countries:


  1. 2.
    3.

Data We'll Compare: (e.g., Population, Official Languages, Land Area)

Lead a brief class discussion. Ask students to suggest countries they're interested in. Then, guide them to choose a simple, quantifiable data point that can be compared across countries (e.g., population in millions, number of official languages, average temperature). Record the chosen countries and data on the board.

Time to Graph!

Create your very own Bar Graph!

  1. Title: Give your graph a great title!
  2. Labels: Label your X and Y axes.
  3. Scale: Choose a smart scale for your Y-axis.
  4. Draw Bars: Make those bars accurate and clear!

Explain the instructions for the worksheet. Remind students to title their graph, label both the X and Y axes, choose a clear scale for the Y-axis, and draw neat bars.

What Did We Discover?

Let's share our insights!

  • What does your bar graph tell us about the countries?
  • Which country has the most/least of your chosen data point?
  • Were there any surprises?

Facilitate a short pair-share, then lead a whole-class discussion. Ask probing questions about their graphs and what they learned about the countries. Encourage them to use vocabulary like 'greater than,' 'less than,' 'most,' 'least.'

Worksheet

Bar Graph Worksheet: International Week

Name: _________________________ Date: _________________________

Global Graphs: Comparing Countries!

Use the data we collected as a class to create your own bar graph below. Remember to:

  • Give your graph a clear title.
  • Label your X-axis (categories/countries) and Y-axis (your chosen data point).
  • Choose an appropriate scale for your Y-axis.
  • Draw accurate and neat bars.













Reflect and Analyze:

  1. What is the title of your bar graph?



  2. What does the X-axis of your graph represent?



  3. What does the Y-axis of your graph represent?



  4. Based on your bar graph, which country has the highest value for the data point we compared?



  5. Based on your bar graph, which country has the lowest value for the data point we compared?



  6. Write one interesting observation you made from your bar graph about the countries we studied.
