# Pie Charts - Answer Key

## Pie Charts

• Pie Chart

### Student Exploration

#### You are what you eat! Or are you?

Table setting.

You are what you eat! Or are you? Investigate this with a Pie Chart! Record the number of servings you eat of each type of food for one week! The United States Department of Agriculture (USDA) has broken down food into the categories of fruits, vegetables, grains, protein foods, dairy, and oils. See http://www.choosemyplate.gov/food-groups/ for more information. Over the course of a week record the number of servings you eat of each type of food.

Want help tracking the food you eat? Create an account at Choose my Plate, by the USDA, and track your foods at https://www.choosemyplate.gov/SuperTracker/default.aspx.

Then create a pie chart representing how much of each food group you ate.

### Extension Investigation

In this activity you will use pie charts as a tool to investigate the food that you eat and compare it to the USDA recommended allowance. Here’s how to do it!

1. For a week record all of the food that you eat and how much. Record your data in a table like that below.
Example of table for recording data.
Food Quantity (how much)
2. Next add two columns to your previous table. Add a column where you indicate which food group(s) that the foods fall into and how many servings that you ate. See http://www.choosemyplate.gov/food-groups/ and https://www.choosemyplate.gov/SuperTracker/default.aspx for more information.
Second Example of table for recording data.
Food Quantity (how much) Food Group(s) # of Servings
3. Then add up all the servings that you ate and how many servings of each food group that you ate in the week. Use that information to create a pie chart representing how much of each food group you ate. If you forget how to do this, revisit the “Pie Chart” concept reading and explanation.
4. Now create a pie chart to represent the recommended allowance of the food groups. According to the USDA, you are suppose to eat 6 ounces (0.75 cups) of grains, 2.5 cups (20 ounces) of vegetables, 2 cups (16 ounces) of fruit, 3 cups (24 ounces) of dairy, and 5.5 ounces (0.6875 cups) of protein foods. Create a pie chart for this!
The graphs for the students’ food journals will vary depending on their eating habits. Here is an example of a pie chart for the USDA recommended daily allowance of the food groups.

Follow-up Questions:

Compare your pie chart to the pie chart for the recommended allowance for the food groups. What do you notice? How are they different? How are they similar?

What food groups should you eat more of? What food groups should you eat less of?
