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
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?
----- 4

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

If we “select” 2 parts of this rectangle, what is the fraction?
4

If we “select” 3 parts of this object, what is the fraction?

If we “select” 3 parts of this object, what is the fraction?
4
