Dr. Math,

I need to come up with creative and effective ways to teach
fractions to some 3rd and 4th graders. We are going to cover parts
of a unit, parts of groups, adding and subtracting, etc. Can you
help? Thanks.

Hi Bianca! The best thing that I can do is point you to the resources
in the Math Forum's Internet Mathematics Library, a searchable list
available at:

http://mathforum.org/library/

One of the lessons (Mars Fraction Hunt by Paul T. Williams) I found through
the Library is replicated below. In particular, you should check out the
fractions/decimals/percents section at:

http://mathforum.org/library/browse/static/topic/fractions.html

An example of a lesson I found there is Fraction City, by Dr. Mavis Kelley:

You can find others at:

You might also try The Eisenhower National Clearinghouse at:

http://enc.org

and the Dr. Math archives at:

I hope this helps.

TITLE: MARS FRACTION HUNT
AUTHOR: Paul T. Williams, Vanguard Honors Program, Phoenix, AZ

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

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.  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.
