# Teaching pie graphs

Third grade math standards require students to represent and interpret data using visual organizers, including bar graphs.

Third-graders are expected to understand how to draw the graphs and answer questions based on graphs. Lessons include teaching the parts of a bar graph, creating the graph and reading the graph to find data. Third-graders need an understanding of the parts of a bar graph before they can accurately read and use this math tool.

Draw a basic bar graph on the board as an example with labels for the different parts, including the title, axes, scale and bars that represent information. Point out the vertical and horizontal axes, including what information each represents. The horizontal typically represents the options, while the vertical shows the quantity. Show several bar graphs with different scales to help third-graders learn how to determine the quantity represented by each bar.

For example, one graph might mark every number, while the lines on another might count by fives, 10s or s.

## Creating pie graphs

The third grade math curriculum typically includes solving problems using bar graphs. This might include one-step or two-step problems, such as finding the total or difference between different bars on the graph. Start with simple tasks. Ask students to find the number represented by each bar, for example.

Move into problems that ask students to compare two different bars on the graph to see how one represents a greater quantity of the measured item. Increase the complexity of the problems as the students improve at interpreting the data. Bar graphs become meaningful to third-graders when they collect data themselves.

One simple way to do this is to have students vote. Ask a question, such as favorite ice cream flavor or how kids get home from school. Each student casts a vote for one of the answer options. You can also have students create their own problems and collect data on their own.Comparing Numbers. Division Basic. Division Long Division. Hundreds Charts. Multiplication Basic.

Inventory Time! Name Your Groups!It is important that students understand the part-whole relationship that exists when creating a pie chart. A circle, or pie, represents the whole of the data set population or sample that is the focus of discussion. The segments of a pie graph can be marked using a protractor and the percentage of degrees that makes up the segment.

However, it is also possible to create a pie graph with concrete materials. With small data sets and frequency data for each category, each value in the same category can be placed along a strip of paper in equal intervals.

The strip of paper is then rolled into a circle. Draw lines to connect the middle of the circle with the boundaries of the categories to create the pie graph. Year 4: Construct suitable data displays, with and without the use of digital technologies, from given or collected data.

Line charts and bar charts have a vertical axis and a horizontal axis. Each axis is labeled to indicate what type of information it contains.

Typical information included on vertical and horizontal axis include:. There are a number of specific words and phrases used to describe and discuss graphs and charts.

Consumer confidence recovered in the second quarter. Have you seen any improvement in customer satisfaction? Unfortunately, we've seen a decline over the past three months. As you can see, sales have plunged in the northwest region. There's been a slip in profits this past quarter. Comedy book sales have deteriorated for three quarters. We project improved sales in the coming months. As you can see from the chart, we forecast increased research and development spending next year.

We predict improving sales through June. There's been a slight decline in sales.

Sales have declined slightly over the past two months.Our graphing units in third grade used to be focused primarily on circle graphs pie chartsbut under the Common Core, bar charts are given a new prominence. Bar charts are intuitively easy to understand for second and third graders, and since they build on and are closely connected to the number line, they follow logically from the other math your students are doing.

While bar charts make comparing the relative size of parts a simple visual exercise, pie charts offer intuitively obvious visual comparisons between parts and the whole.

Teaching circle graphs also enables our students to practice fractions in a fun, easy-to-grasp way. This lesson plan focuses on gaining a visual understanding of whole-part relationships through the use of a simple circle graph, and also gives students an opportunity to practice fractionsas required by section 3. To understand a pie chart circle graph and to be able to deduce information about the relative size of the parts shown in it.

To be able to compare fractions by reasoning about their size Common Core 3. Start with a review of fractions. Show the students your white circle, and ask what they think of when they see it. Give them some time to discuss what a circle means to them, and validate their feelings and opinions as they share them.

After the students have answered, tell them that since the whole circle meant to you a whole of anything — a whole class, a whole country, a whole bag of skittles—the colored sections mean, to you, half of anything.

Half a bag of skittles, half a class, half a country. Ask half the class to hold up their hands; the front half, the back half, or the side half. Then tell them that you could use this circle to show how many children had their hands up; the colored section would be the children with their hands up, and the white section would be the other children. Ask your students if they know how much of the circle is shaded now.

Ask a quarter of the class to raise their hands; you will probably have to mark off the demarcation lines for the quarter. Tell them it is called a pie chart, and ask them if they know why. Ask which color is the biggest favorite. Then ask which of the three explicitly listed colors the least amount of children seem like. Now tell them the class was made up of twenty students, and ask them how many students liked blue.

Ask whether fewer or more than six students have green for their favorite color, and whether or not five students have purple for a favorite color.
