2. WHAT IS A FRACTION?
A fraction is a number that
tells us parts of a whole.
This is a whole,
one big circle!
These
are
parts!
3. WHAT IS A FRACTION?
LOOK AT THIS PIZZA! IT’S A
WHOLE PIZZA
This pizza has been cut into
half! It’s now TWO parts. In
fractions we call this “one half”
we write this as
4. WHAT IS A FRACTION?
LOOK AT THIS PIZZA!
This pizza has been cut into
three equal parts. We call this
one third and write it as
5. THE WHOLE PIZZA CUT INTO
THREE EQUAL PARTS GIVES
US THREE THIRDS. THINK
ABOUT JUST ONE SLICE. WE
CAN WRITE THIS USING A
FRACTION
6. THINK ABOUT TWO SLICES.
TWO SLICES IS TWO THIRDS.
WE CAN WRITE TWO THIRDS
AS
7. THE TOP NUMBER OF THE
FRACTION TELLS US HOW MANY
SLICES WE HAVE.
WE CALL IT THE NUMERATOR.
The bottom number tells us how
many parts in the whole pizza.
We call it the denominator.
8. LETS TAKE A LOOK AT
DIFFERENT TYPES OF
FRACTIONS.
This is a fraction. The numerator is less
than the denominator.
This is an improper fraction. The numerator
is more than the denominator.
This is a mixed number. It has a whole
number and a fraction combined.
9. GREATER THAN OR
LESS THAN?
This is less than.
This is greater than.
10. ADDING
FRACTIONS
Remember that fractions are made
up of two numbers. The number
above is called?
Numerator
And the number below is called?
Denominator
11. TO ADD FRACTIONS, THEY
MUST HAVE THE SAME
DENOMINATOR.
We cannot add because they do not
and
have the same denominator.
Before you add two fractions make sure the
denominators are the same.
