The important thing about fractions is they represent equal parts of a whole or a group.
• The circle has not shaded blue. • The circle has one-fourth not shaded
blue. • The circle has 1 out of 4 equal parts not
shaded blue. • The rectangle has shaded green. • The rectangle has two-thirds shaded
green. • The rectangle has 2 out of 3 parts shaded. But the important thing about
fractions is they represent equal parts of a whole or a group.

• Each fraction has a numerator• The numerator is the top number• The numerator represents the
number of equal parts you are talking about.

Numerator
This numerator tells us about 1 of the 2 equal parts. ½ of these
brownies are frosted.
½ of the M&Ms are green.

• The smaller the numerator, the fewer parts represented

• The larger the numerator the more parts represented

• Each fraction has a denominator• The denominator is the bottom
number • The denominator represents the
number of equal parts in the whole or group.

Denominator
This denominator tells us there are 2 equal parts.
These brownies have 2 equal parts.
There are 2 M&Ms in this group.

• Some fractions are equivalent, this means they are equal.
• Equivalent fractions take up the same amount of space
• Equivalent fractions have the same value, even though they are represented by different numbers.
