Center Focus

Length of Foot vs. Height

  1. You will need measuring tape, rulers, paper, and a prepared chart with columns labeled Name, Foot Length and Height posted at the center.
  2. Students will trace their foot on a piece of paper and measure the length.
  3. Then they will need to work with a partner in order to measure their height.
  4. Have them find out the ratio of their height to their foot length. How many of their "feet" tall are they?
  5. Working with their partner, they need to find the average ratio between the two of them. Then ask them this problem: Using this average ratio, determine the height of a giant with a 21-inch foot length.
  6. Follow-up on this center when everyone has completed the tasks by creating a graph to show the students and their foot length vs. height ratios.
