How do You Measure Up? (with the TI-10)

Activity Overview

Students measure weight, height, and length with the help of a balance, scales, rulers, yardstick, and tape measures. They use their TI-10 to find proportions and to round off answers to whole numbers.

Before the Activity

  • See the attached PDF file for detailed instructions for this activity
  • Print pages 137 - 147 from the attached PDF file for your class
  • During the Activity

    Distribute the page to the class.

    Follow the activity procedures:
    Activity A:

  • Discuss the characteristics (height, weight, speed, length, strength etc.) of animals, and read the book: Biggest, Strongest, Fastest, to the class

  • Activity B:
  • Compare the weight (in pounds) of an average adult male to an elephant
  • Use the calculator to determine the approximate number of adult males whose combined weight equals the weight of one elephant

  • Activity C:
  • Reread the book, observe that an ant can lift 5 times its own weight
  • Calculate the weight a 60-pound adult can lift if he were as strong as an ant
  • Determine the number of books that will weigh 300 pounds

  • Activity D:
  • Tear a length of tape that measures the height of a student
  • Use a ruler to mark 12-inch sections and number them
  • Calculate the height of the student
  • Use the calculator to determine the number of students whose combined height will equal the height of the giraffe

  • Activity E:
  • Measure the wall length and use the calculator to get the perimeter of the classroom
  • Determine the length of the tentacles of a jellyfish

  • Activity F:
  • Convert feet to inches and find the length of the room
  • Note a snail travels at a speed of 8 inches per minute
  • Find the time taken by the snail to cross the room

  • Activity G:
  • Note a flea can jump 130 times its height
  • Determine how high a 4-foot child can jump if he could jump like a flea
  • After the Activity

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