Interpreting Pie Charts
Key Stage 2/3 (Ages 10-14)
Mathematics
25
This lesson corresponds to the Edexcel curriculum, focusing on data representation and interpretation.
| Step Number | Step Title | Length (minutes) | Details |
|---|---|---|---|
| 1 | Introduction | 5 | Briefly introduce pie charts; discuss why they are useful in representing data visually. |
| 2 | Components of a Pie Chart | 10 | Explain the different parts of a pie chart (slices, labels, legend); show examples. |
| 3 | Interpreting Pie Charts | 10 | Present a pie chart on the projector and guide students through interpreting the data; pose questions to facilitate discussion. |
| 4 | Group Activity | 15 | Divide students into small groups; provide each with a pie chart and set of questions to interpret the data collaboratively. |
| 5 | Create Your Own Pie Chart | 7 | Have students use given data (e.g., survey results) to create their own pie chart on graph paper; encourage the use of colors and clear labeling. |
| 6 | Wrap-up & Homework Assignment | 3 | Summarise the key points of the lesson; assign homework to create a pie chart from a new dataset provided in print. |
"Good morning, everyone! Today, we are going to dive into the world of pie charts. Can anyone tell me what a pie chart is? [Pause for responses] Great answers! Pie charts are really useful because they visually represent data in a way that makes it easier to understand. Have you ever seen one before? [Wait for a few responses] Excellent! Today, we're going to learn how to interpret them, understand their components, and even create our own. Let's get started!"
"Now, let’s talk about the different parts of a pie chart. [Draw a simple pie chart on the whiteboard] Can anyone tell me what these sections are called? [Point to slices] That's right! These are called slices. Each slice shows a portion of the whole data set.
"Next, we have labels. [Point to the labels] The labels tell us what each slice represents. And lastly, we often see a legend, which is a key that helps us understand what each slice means in relation to the whole chart. [Show pie chart examples on the projector]
"Here are a few examples of pie charts. Look at how they are labelled and organised. What do you notice about the sizes of the slices? [Encourage students to share their observations] Excellent! The larger the slice, the greater the proportion it represents in the data."
"Now, let’s practice interpreting a pie chart together. [Display a pie chart on the projector] What do you see? Let’s break it down.
"First, what is the overall subject of this pie chart? [Wait for responses] Good! Now, let’s look at the slices. If a slice represents 25%, what does that tell us about that part of the data? [Discuss responses] Great job!
"I want you to think critically here. What does it mean if one slice is significantly larger than another? [Encourage discussion] Exactly! It indicates that this category is more prevalent within the total data. Okay, let’s move on and challenge ourselves with some group work."
"Now, I’d like you to work in small groups. [Divide students into groups] Each group will receive a pie chart along with a set of questions to interpret the data collaboratively.
"Take about 15 minutes to discuss your pie chart, answer the questions, and be prepared to share your findings with the class. Remember to think critically—why do you think the data is represented in this way? What conclusions can you draw from it?"
"Now that we've gained some insight, it’s your turn to create your own pie chart! Here’s some data from a recent survey we conducted. [Distribute the data]
"Using graph paper and colored pencils, I want you to create a pie chart that accurately represents this information. Make sure to use different colors for each slice and label everything clearly. You have about 7 minutes to work on this. Let your creativity shine!"
"Okay, everyone, let’s come back together. What did we learn today about pie charts? [Summarise key points based on student feedback] Excellent work today!
"For your homework, I want you to create a pie chart based on a new dataset I'm providing on this worksheet. Reflect on what this data tells you and write a short description explaining your chart. Remember, I'll collect your homework, but you won’t present it in front of the class.
"Before we end, does anyone have any questions? [Answer any questions] Fantastic! I look forward to seeing your pie charts!"

"Can anyone explain how the size of a slice in a pie chart correlates to the data it represents? What does it tell us about the information being displayed?"
"Imagine you have a pie chart with four slices, and one slice is twice the size of the others. What can you deduce about the data that this chart is showing?"
"If you were to create a pie chart of your favourite fruits, how would you decide what data to use for each slice? What considerations would you make?"
"How might the colours you choose for each slice of a pie chart affect how someone interprets the information? Can you give an example?"
"Why do you think it’s important to include labels and a legend in a pie chart? How would the chart change if these elements were missing?"
