TITLE: MARS FRACTION HUNT
AUTHOR: Paul T. Williams, Vanguard Honors Program,
Phoenix, AZ
GRADE LEVEL: Appropriate for grades 3 - 5.
OVERVIEW and PURPOSE: This lesson is designed to give the
students practice in the use of fractions, changing
fractions, using equivalent fractions, and paying attention
to detail. This lesson works well at fourth grade level,
but I find it can have good use with advanced third graders.
OBJECTIVES: The student will be able to:
1. Divide a word into appropriate fractional parts
2. Use equivalent fractions to correctly divide words
3. Pay attention to details in instructions relating to
"first, "last", "second", etc.
4. The student will analyze the clues and decode the
message.
RESOURCES/MATERIALS NEEDED: A MARS candy bar, classroom
globe (on a small stand or cradle), activities paper. Before
the activity, the MARS bar should be hidden under the
classroom globe. The ANSWER KEY for the activity is:
FOR THE FIRST ONE TO FINISH THIS THERE WAITS A PRIZE IF YOU
USE YOUR HEAD PERIOD CLUE MARS IS DIRECTLY BENEATH THE SOUTH
POLE PERIOD GO LOOK
ACTIVITIES: (See "Resources/Materials Needed" for necessary
preparation and activities page) The student will write the
appropriate parts of the words on the line to form a new
word. When the message is complete, the first student to
decode the message will be rewarded by finding the hidden
candy bar (MARS bar).
TYING IT ALL TOGETHER: After the winner has claimed his
prize, the assignment should be reviewed. During this
exercise, many of the students claim that "no such words
exist." This is where it is necessary for them to pay
attention to the details of the instructions. Usually the
brighter students will be the ones to win; in that case, the
teacher could team the students into pairs or small teams--
if this is done, it is best to be sure to have a MARS bar
available for each winning team member.
