What You Say Is What You Get

Objective:   Comparing and Ordering Fractions

Purpose:Student will order fractions using models.  Students will also model equivalent fractions, then discuss the similarities and differences.
 

Materials:  10 large Butternut candy bars. 5 sandwich bags.  Cut 2 candy bars in thirds, fourths, sixths, eighths, and twelfths.  Place same size pieces in unmarked bag.  Fraction models.
 
 

Procedure:  As an introduction to this lesson.  Teacher will prepare the candy before class.  Show the students the candy in the unlabeled bags.  Tell the students to answer all the questions and you will receive the piece of candy you request.

Show that fractions equivalent to a given fraction can be found by multiplying the numerator and denominator by the same number.  Student should also see that dividing the numerator and denominator of a fraction by the same number will produce an equivalent fraction.
