FRACTIONS

Let’s draw a rectangle, and divide

it in two equal parts...

The red part of the rectangle represents a

fraction…1/2 (one half)

Now, let’s draw a circle and divide it in two

equal parts...

The red part of the circle represents a fraction…

1/2 (one half)

Very Good!!! Now let’s draw another rectangle and divide it in three

equal parts...

The red part of the rectangle represents

another fraction… 1/3 (one third)

Very Good!!! Now let’s draw a circle and divide

it in 4 equal parts...

The red part of the circle represents a fraction…

1/4 (one fourth)

Very Good!!! Now you know what a Fraction

is !!! Remember that in a fraction the number

below the line indicates the total number

of equal parts in which an

object is divided…

and the number above the line

indicates the number of parts “selected” in

that object...

So, you can represent different fractions with the

same object … For example, look at the following object...

Now see how this rectangle can be used to show different fractions….

If we “select” 1 part of this rectangle, What is the

fraction?

If we “select” 1 part of this rectangle, What is the

fraction?

If we “select” 2 parts of this rectangle, what is the

fraction?

If we “select” 2 parts of this rectangle, what is the

fraction?
