If you remember, a fraction is a
part of a whole.
It can be many objects like 2 cookies out of
4 total cookies, or one object, like 1 slice of pizza from a pizza
with 16 slices.
As with all fractions, the
objects have to be divided into parts of equal size.

In this picture we learn how to divide into fourths.
First
you must divide an object into 4 equal parts. When you write a
fraction, you show on the bottom how many parts in the whole there are. On the
top of a fraction you write how many of the parts you have selected out of the whole.

←
Part (Numerator)
4 ←
Whole
(Denominator)
The number on the top of a
fraction is also called the numerator.
The number on the
bottom is called the denominator.
When we name a fraction we
use the numerator's normal name and the denominator's ordinal name (third,
fourth, fifth. . . )
Let's work with the fraction
one half or :
1
2
That
means 1 part out of 2 total parts. Remember, that to have one
half the two parts must be equal in size.
Let's try
these problems. Point to each shape that shows two equal parts:
| 1. |
  |
|
| 2. |
  |
|
| 3. |
  |
|
| 4. |
  |
|
| 5. |
 |
|
| 6. |
 |
|
| 7. |
  |
|
| 8. |
 |
|
| 9. |
  |
|
| 10. |
 |
|
| 11. |
|
|
| 12. |
 |
|
| 13. |
|
|
| 14. |

The next time you eat a
piece of pizza, count how many total pieces of the pizza
there are.
What fraction did you just eat?

The
body is a unit, though it is made up of many parts; and
though all its parts are many, they form one body. So it is
with Christ...Now the body is not made up of one part but
of many. If the foot should say, "Because I am not a hand,
I do not belong to the body," it would not for that reason
cease to be part of the body. And if the ear should say,
"Because I am not an eye, I do not belong to the body," it
would not for that reason cease to be part of the body. If
the whole body were an eye, where would the sense of hearing
be? If the whole body were an ear, where would the sense of
smell be? But in fact God has arranged the parts in the
body, every one of them, just as he wanted them to be. If
they were all one part, where would the body be? As it is,
there are many parts, but one body.
