```Math Technique in Multiplication and Division of FractionsGarth, Frieda                Farragut Career Academy                             762-2421                                                Instructional Objectives:

1. To multiply fractions by whole numbers and fractions.
2. To divide fractions by whole numbers and fractions.

Review Objective:

To review unit concepts and skills.

Apparatus Needed:

2-Poster Boards (size 22" x 28") divided in three parts: center
square (8"x 8"); second section (9" x 7 1/2") from center point
of the poster; third section (out side spaces) (5 x 3 1/2") from
second section. Center square is used for placing different
numbers as the whole number or mixed fractions. The second
sections are used for fractions. The third sections (outside
spaces) are used for one or two answers. Black marker, ruler,
magnetic tape and nine (9) squares (8"x8") with numbers from
2, 3, etc. The fractions were placed in the second section with a
black marker before laminating, which was done at the Bd. of Ed.,
3th floor west.

Recommended Strategy:

This mini teach is directed toward learning disabled students,
but this is a problem common to all students. To understand the
basic concepts of fractions, demonstrate step-by-step procedures
to be used in this lesson.  Teacher will use center square of
the posterboard, placing a whole number in the center. Fractions
are on the second section of posterboard and the third section
of the posterboard will be used to compute student answers.
Example 8 x 3/4 = 6; 8 x 1/6 = 1 1/3. Posterboards will be
attached to blackboard with magnetic tape. These steps
(multiplication or division) may be repeated more than once,
because there are eight fractions on each board and a different
whole number can be used as often as needed. Students will note
that their answers can be found simply by multiplying whole
number by numerator, then divide by the denominator to get the
product. Teacher will introduce concept of dividing fractions
with second posterboard in the same method, step-by step
procedures in dividing fractions. Give the numerators and
denominators colors, like red for numerators and green for the
denominators. Students can see the interchanging of numerator
and denominator, which is called the reciprocal of the
fraction. Example, the reciprocal of 3/4 is 4/3. Have the
students complete the exercises, this can be used to provide
stimulation and practice.
This step may be repeated more than once, because there are eight
fractions on each board and use a different whole number, if you
so desire. Have the student to note that answers could be found
simply by multiplying whole number by numerator, then dividing by
the denominator to get the product.
