Graphing the Popularity of Breeds of Dogs


Learning Objectives

Students learn fractions and percentages in real-life applications.


Grade Level

Grades 6-8


Common Core Standard

Solve real-life and mathematical problems using numerical and algebraic expressions and equations.

Use random sampling to draw inferences about a population.

Investigate patterns of association in bivariate data.


Materials Needed

Computers with internet access

Copes of raw data for each student



Prior to Day of Lesson

  • Students will need to conduct a survey to determine the favorite dog breed among students. Ideally all students in grades 6-8 would be surveyed in order to create a large data set. Use this website for information about the breeds. You may choose 10-12 to offer to the students in order to expedite the voting process. Breed Information


  • Depending on students’ prior knowledge, conduct a review of fractions and percentages.

Explicit Instruction/Teacher Modeling

  • Give each student a copy of the raw data collected.
  • Instruct them to work in groups to analyze and sort the data.


Independent Working Time

  • Once students have analyzed their data and they know how many students voted for each breed, instruct students to display their data the following ways:
    • Create a spreadsheet to clearly represent your data.
    • Create a fraction that shows how many students like AKC’s most popular breed, Labrador Retriever, by grade level. Represent this information in a pie chart. For example, 30/60 sixth graders report that Labs are their favorite breed of dog. 30/60 can be reduced to ½. This pie chart represents ½.
      6th grade pie
    • Create a bar graph to demonstrate the number of students that liked each breed of dog.

Review and Closing

  • Have students share their data with the class.
  • Have students think, pair, share about how graphing helps to share data more clearly.
