Measurement and Geometry

Published on 06/09/2008

Activity Overview

Students explore the use of manipulatives to conduct simple geometry and measurement activities.

Before the Activity

  • See the attached PDF file for detailed instructions for this activity
  • Print student activity sheets for each separate section: Map It! pg 75, Only Half There? pg 79, No More Peas, Please! pg 83, Do Centimeters make Me Taller? pg 88, What's My Ratio? pg 92-93, Ratios in Regular Polygons pg 97-98, Predicting & pi; pg 102.

  • During the Activity

    Distribute the page to the class.

    Follow the activity procedures:
    Map It!:

  • Read a story, identify the locations of different places in the story, decide the distance between each set of places in the story, and create a map with a legend.

  • Only Half There?:
  • Use measuring tools and calculators to make half-sized drawings

  • No More Peas, Please!:
  • Use nonstandard units of volume and calculators to estimate the number of peas it would take to fill a room

  • Do Centimeters Make Me Taller?:
  • Use measuring tools and calculators to find pairs of measurements and form ratios
  • Compare the ratios and make conclusions about using different units to measure lengths

  • What's My Ratio?:
  • Use linear measurement and calculators to investigate proportionality and determine the constant ratio between similar figures

  • Ratios in Regular Polygons:
  • Use linear measurement and calculators to investigate the ratios between corresponding parts of regular polygons

  • Predicting & pi;:
  • Use linear measurement and calculators to discover the existence of & pi;, the constant ratio between the circumference and the diameter of a circle
  • After the Activity

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