1
Equivalent Fractions
• By Mr. Bales

Objective
• By the end of this lesson, you will be able to
find equivalent fractions.
• Standard 4NS1.5 - Students willexplain
equivalence of fractions.

Warm-Up
• Using the grid paper on your desk, please cut the
paper in half and write the fraction that each
represents.
• What is the fraction for each part?
• Now, cut one of those pieces in half again.
• What is the fraction for each part for these
pieces?
• How many fourths equal one half?
• Now, cut each of the fourths in half.
• What is the fraction for these?
• How many eighths equal a half?

Introduce
• Ryan H. has 8 fish in an aquarium. Four fish are
green. So, Ryan says that 4/8 of the fish are
green. Could Ryan use another fraction to
represent 4/8?

5
Equivalent Fractions
• The fractions models to the left show that 4/8 is
the same as 1/2.
• Fractions that name the same number are
equivalent fractions.

Find Equivalent Fractions
• Find three fractions that are equivalent to 4/8.
• To find equivalent fractions, you can use
multiplication
• or division.
• One Way Multiply
• 4 x 2 8
• 8 x 2 16
• Multiply the numerator
• and the denominator
• by the same number, 2.
• Another Way Divide
• 4 2 2
• 8 2 4
• Divide the numerator and the denominator by the
same number, 2.

So, 8/16, 2/4, or 1/2 could be used to represent
4/8.
