After which, students will be introduced to alternative ways to measure distance, time, and temperature.  My lesson will be targeted to fourth and fifth graders.  My main focus is to allow students to use parts of their bodies to calculate measurements of different objects and areas of space.  The activities will be designed to lead the students to an understanding of the measuring system presented.  The students will then be able to graph and use their informational data to compare with the other students.     The students will begin with the definition of a Basic Measurement.  A Basic Measurement is the distance between two points that can be measured and may be named length, width, height, radius or diameter.  In order to use body parts for measuring, the Standard Metric system should be primarily taught.  This will help the student and improve his understanding for measuring with alternatives.  I am going to work with the simple idea that the distance between two points can be measured. Strategy:                               INTRODUCTION          Two students are asked to open the activity with volunteering to participate in the unannounced subject.  They are each given a Superball.  In class there are two stairways, where the students are going to engage in a race to the top of the stairs using the Superball.  They are to bounce the Superball once on each step as they race to the top.  The other students are asked to clap their hands as a measuring tool for time.  The recorder announces a winner, which is the student who has made it to the top of the stairs using the least amount of claps.  The instructor should not dictate to the students the rhythm or how to clap their hands.  The observation point is to watch and listen to the way the students will or will not cooperate with one another concerning the rhythm.  Now the students should be asked what they think they just accomplished.  The rounded response may be: calculated time by using their body parts, which were their hands.     Students may now be told that their body parts can be used as measuring devices.  The remaining activities will allow the students to participate in fun activities that involve measuring length, distance, and temperature, using their own body parts.                       Activity: MEASURING THE WHITE BOARDS     Using the span of their hands, the students will create their own hand ruler.  Each student will use a undefined length of register tape paper and measure the span of their hand.  They will mark the paper after each hand measurement.  The length may be any that they desire.  This will promote interest on how the students will measure the white boards.  If one student measures 10 (ten) hand spans and another measures 5 (five) hand spans, then they should realize that the one with the shorter hand ruler will have to add twice as many times as the other.      When students have completed this activity, they should see the resulting data and notice that all hand measurements are not the same.  This will promote questions as to why the hand measurements were different.  The instructor can now discuss the advantages and disadvantages of using your body parts as an alternative to the Standard Metric System.  Some answers that evolved were:everyone has different hand sizes, some small, some big, you always have your body parts with you as an advantage.                        Activity: BODY LENGTH OF THE ROOM
Each student will now use their actual body length to measure as a measuring
tool to calculate the length of their classroom.  Students will choose a partner
and one student will lay on the floor closest to a wall to start measurement.
The other student will place his foot at the end of the student's foot who is
lying down.  The end of the student's foot will be a measurement of one complete
body for that student.  The group will repeat this until the group has measured
the entire length of the room, one way.  Students are then advised to try this
at home and measure different parts of their home with their body length, with
the help of another.

Activity: MEASURE GRASS LENGTH USING YOUR FOOT                Promote discussion on shoe sizes.  Explain that they vary, and that women shoe sizes are different from men shoe sizes.  Students will go outside.  Each child will use their own foot measurement to measure the length of the grass.  They will start at the edge of the grass, putting one foot in front of the other and count until the distance is completed.  Complete and compare the data with other students.                          Activity: MEASURING TEMPERATURE
Students are asked to use body parts to calculate a general estimate of
temperature.  Materials used includes a cup of hot water, a can of cold pop, and
a warm towel.  Students will touch each object, telling the other students which
objects are warmer and colder without using a thermometer.  Students will
discuss results and realize that they just used their body parts to measure
temperature.  Some students may experiment and us different body parts to
measure temperature.  Some students used their fingers, tongue, and jaw cheeks.

Assessment:    Students should now understand that they can use alternative measuring devices.  The fun part of their data is that they can use their very own body parts.  They are free and always with you.  Disadvantages may include the fact that measuring with body parts can also result in inaccurate measurements because everyone can have different size body parts.     Students will be given a metric ruler.  They will be asked to find a part of their body that measures exactly one inch.  They can test their findings by measuring a sheet of notebook paper.  Now the students will understand that they have a permanent measuring tool right on their body and can be used at all times. VOCABULARY                              MATERIALS
