Fraction Finder
Can you identify the fractions? Can you identify the parts of a fraction?

Slide 2:

What is a fraction? Fractions are parts of a whole.
If an amount is divided into equal
parts, or fair shares, we can
understand and name the fractions. A fraction is the top number (called the numerator) divided by the bottom number (called the denominator).

Slide 3:

Some examples of fractions: A graphical example of fraction 1/3 is shown by the pie chart below. The pie is divided into 3 equal parts. The blue part is equal to one third of the pie, thus 1/3. A graphical example of fraction 7/8 is shown by the apples below. A box holds 8 apples. One apple is missing from the box. There are 7 apples left in the box, thus 7/8. Some examples of fractions: 1/3 2/5 7/8 A graphical example of fraction 1/3 is shown by the pie chart below. The pie is divided into 3 equal parts. The blue part is equal to one third of the pie, thus 1/3. A graphical example of fraction 2/5 is shown by the marching men below. There are five marching men in the illustration. There are 2 men in orange uniform, thus 2/5. A graphical example of fraction 7/8 is shown by the apples below. A box holds 8 apples. One apple is missing from the box. There are 7 apples left in the box, thus 7/8.

Slide 4:

3 Questions to Ask: 1. What is the whole and how big is it? * All wholes are not the same. * 1/2 of $10.00 is not the same as 1/2 of $100.00. 1/2 = $5.00 1/2 = $50.00

Slide 5:

2. Into how many equal parts
has the whole been divided? * If the whole has been divided into
equal parts, we can understand
and name the fractions,
and the number of parts tells us
what fraction of the whole each part is. * The denominator tells us what
fraction of the whole each part is. If an 8 inch pie is divided into 4 equal parts, the denominator is 4, and each slice is ¼ of the pie.

Slide 6:

3. How many of the equal
parts are we using? * This tells us the actual amount of the whole
that is being dealt with. * The numerator of a fraction tells us
how many of the equal parts we are using. If we ate 1 piece of the 8 inch pie that was divided into 4 equal pieces, the numerator is 1, and we would have eaten ¼ of the pie.

Slide 7:

Do You Really Know What
The Questions Mean? For Example:
1. ½ the class tells us that there are two equal parts
and we are using one of the parts. Do we know
the size of the whole class?
2. 2 pieces of cake tells us we are using 2 of the
pieces. Do we know how many pieces there are in
all, or if they are equal?
3. ¼ of a dollar tells us the whole is $1.00, it is
divided into 4 equal parts of $0.25 each, and we
are using 1 of the parts, or $0.25. We can answer
all three questions about this amount, so we
really understand what it means.
