Review of Basic Fraction Concepts
January 23^{rd}, 2008
Lesson Rationale: To review fractions as parts of a whole (ONE), fractions on number lines, and uses of fractions.
Understanding these concepts will help students move on to new and more complex ideas regarding fractions.
PA Standards: 2.1.4
Anticipatory Set: Hold up beaded necklace for class to see. Tell students the necklace represents the whole or
“ONE”. Tell students how many beads are on the necklace (29). Explain that each bead on the necklace is one part
of the whole or 1/29. Point to different amounts of beads and ask students what fractional part of the whole they are. 4/29, 18/29, etc.
Materials: Math Journal 2 pg. 189191
Student Reference Book pg. 41
Pattern blocks
Necklace made up of equal sized beads
Ruler
Flashcards –on one side, draw a circle divided up into parts, with
a fraction of the parts shaded. On the other side, write the fraction of shaded parts to the whole
Objective 
Procedure 
Assessment 
Review
fractions as parts of whole (ONE) 
Explain
that fractions are always a fraction of something, for example ¾ of an inch, ½ cup, 1/29 of a necklace 
This
would have been done during the anticipatory set when the students are asked what fractional part a certain amount of beads
are to the whole necklace. 
Review
that all parts of fractions must be equal 
Hold
up necklace and tell students that all of the beads are equal
Ask
class the best way to divide up a giant pizza to ensure that everyone would be happy 
Hear the students’ answers to the pizza question. (example answer: everyone would have an equal slice) 
Review
uses of fractions

Share
one use with students, for example: height (5’7 ¾’’)
Have
students discuss in small groups some ways fractions are used outside of math class
Turn
to page 41 in SRB for some more examples 
Have
one student from each group share

Objectives 
Procedure 
Assessment 
Review
terms, numerator and denominator 
Ask
class how they would define numerator and denominator
(Denominator
names the number of equal parts the whole is divided into and the numerator tells the number of parts of the whole that are
being counted)
Tell
class that fractions are another way of writing division problems (1/4 = 1divided by 4) 
Whole
group discussion on definitions 
Students
will understand how to use pattern blocks to determine fractional parts of a whole 
Students
turn to page 189 in Math Journal while pattern blocks are distributed.
#1 is
done as a model for the class, draw students’ attention to the “whole” box
Students
get into pairs and complete the problems on pages 189190. 
Go over
the problems assigned, discuss answers

Review
fractional parts of number lines 
 In
Math Journal, do #9 and #10 as a class, then assign #1114 to do independently 
Go over
as class, being sure to mention that numbers such as 2 ½ are called mixed numbers (a whole number followed by a fraction)

Adaptations: Students having difficulty understanding how fractional parts make up a whole may use the homemade
flashcards to assist them. Students who need enrichment activities may be given rulers to construct their own equilateral
triangles on paper. They will cut their triangles out and divide it into 2 equal parts, then 3 equal parts.
