In the following lessons, students participate in an activity in which they focus on gathering, representing, and
interpreting data about pizza choices. Students use surveys to obtain actual data. This unit was adapted from the article "Ideas: Pizza," by Sharon L. Young, which appeared in The Arithmetic Teacher, April, 1991, vol. 38, no. 8, pp. 28-33.
Math Content
Students will:
- collect and analyze data,
- represent data through physical and graphical means,
- draw conclusions from the data,
- communicate their findings to fellow classmates,
- make a double-bar graph to display information about their favorite pizza
toppings, and
- explore the mathematical idea of combinations of two items.
Individual Lessons
Lesson 1 - Pizza at Home Students survey members of their community to determine preferences about pizza. Students compare their results with their classmates and create graphs of their data. Lesson 2 - Favorite Pizza Toppings Using a survey, students collect data about favorite pizza toppings. They create a double-bar graph and discuss their graphs with other members of the class. Lesson 3 - Pizza-Topping Combinations Using the pizza topping theme from the previous lesson, students explore the mathematical idea of combinations. Students also discuss whether or not order matters.
