Mars
Fraction Hunt
|
Grade
Level: 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 or other treat with a label of "MARS"
placed on it by the teacher, classroom globe or map of the world (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 CLUE MARS IS DIRECTLY BENEATH THE SOUTH POLE
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.
