Activity Overview

Students explore and use the concept of ratio in a real-world situation. They will make judgments regarding accuracy and precision of measurement.

Before the Activity

  • See the attached PDF file for detailed instructions for this activity
  • Print pages 59 - 63 from the attached PDF file for your class

    		•

    		During the Activity

    		Distribute the pages to the class.

    Follow the Activity procedures:
  • Divide the class into teams of four
  • Measure and record the distances between the features of the statue picture
  • Measure and record the distances between features on each team member's face with the help of a string and ruler
  • Calculate ratios of facial features
  • Record the mean average ratios of each member (to the nearest thousand), mean average ratios of the group, and the class mean average ratios on the Student Worksheet
  • Compare the individual average ratios to the ratios for the Greek statue and determine which ratio is closest to the Golden ratio

    		After the Activity

    		Students will complete the Student Worksheet and analyze the results.

    Review student results:
  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
