TITLE:  SMILE METRIC STYLE

AUTHOR:  Deana Metder

GRADE LEVEL/SUBJECT:  Appropriate for grade 4-8

OVERVIEW:  Using the metric system can be very confusing and difficult
for many students. This activity enables the  students to practice
working with the metric system. 

OBJECTIVE(s):  The students will be able to:
  1. Accurately use a metric ruler to measure length.

  2. Accurately read and record measurements taken in centimeters and
     millimeters.

  3. Find a sum of multiple metric measurements.

  4. Compare and order individual measurements.

  5. Use a histogram to graph their results.

RESOURCES/MATERIALS:
Student Materials = metric ruler,  crayons or markers, pencils, paper.

Teacher Materials = Chalkboard, chalk, large piece of construction paper
or butcher paper, graph paper.

ACTIVITIES AND PROCEDURES:
  1.  Divide the class into groups of four.

  2.  Each student will measure and record the length of each person's smile
      in their group.

  3.  The students need to check their results against the results of the
      rest of the group.  If there are any discrepancies the students should
      verify the results as a group.

  4.  When an accurate measurement has been obtained for each child the
      results are recorded on the chalkboard as each child records them
      at their seat.

  5.  Order all the measurements from least to greatest.

  6.  Graph your results.

  7.  Find the sum of all the smiles in your classroom.  Don't forget the
      teachers, it is often the largest because the students are so involved
      in this activity.

  8.  Create one smile out of construction paper that is the length of the
      of all the smiles in your room.  

TYING IT ALL TOGETHER:
This lesson can be completed as one lesson or extended to several,
depending on the level and ability of the class.  A fun extension to this
activity is to challenge other classes to measure their smiles and gather
data.  This data can then be compiled and totaled by class.  A graph is then
constructed comparing individual classes and posted in the main hall. The
graph generates a lot of interest and motivates the students to measure
and compare many other objects.
