What are
Equivalent Fractions?
• Fractions that are equal. The number of
equal pieces are different, but the fraction’s
value (out of the whole) is the same.
• As an example, think of a two-slice pizza that has
then been cut into four slices, six slices, etc. The
size of the original pizza hasn’t changed!

Which Fraction is Larger?
5/6 11/12
or
11/12 is bigger because it is only
1/12 away from being a whole.
5/6 is 1/6 away from being a whole.
Twelfths are smaller pieces than sixths.
In other words, 1/12 is smaller than 1/6,
so 11/12 is the larger fraction.

Making Spinners
Color the spinner so
that it will land on red
about 50% of the
time.
Color the spinner so
that it will land on
blue about 1/4 of the
time.
What fraction and percent of the spinner is yellow?
1/4 or 25%
