What is a fraction?

• A symbol that is used to name equal parts of a whole.

• A fraction has a NUMERATOR.• The numerator is the top number and it

names the part that is shaded or unshaded.• A fraction has a DENOMINATOR

• The denominator is the bottom number and it names the total number of pieces in the whole.

Here’s a Hint…

The number in the NORTH is the Numerator!

The number that is DOWN is the Denominator!

Ordering Fractions

• You will be asked to order fractions from Greatest to Least and from Least to Greatest

• You have three strategies to choose from:

1. Draw a picture2. Use Bottoms Up3. Use Fraction Fringe

Since 1/3 was largest 2 times, it is the largest fraction! 1/6 is next, followed by 1/9.

Finding Parts of a Set

When a picture is given, put the items into groups based

on the number in the denominator.

1 of 9 books = 3 books in each group

Finding Parts of a Set

When a picture is not given, you have two choices:

1. Draw a picture and solve!2. Do the math!

1 Of 64 =8

?

x

=

8 times what = 64?

Mixed Numbers• A mixed number is a whole

number and a fraction combined

Mixed Numbers

• Count the WHOLEs first

• Then find the FRACTIONal part

Fraction Problem Solving

• USE YOUR STRATEGIES!!! Do not try to work out the problems in your head !!!

• Review all of the tricks and hints in this slideshow!

• Review your notes from class!• PRACTICE! PRACTICE! PRACTICE!

Why do I need to know this stuff?• Fractions can and will help you in real life. In order to

figure out how to make only part of a recipe because you do not want to feed ten people, but only five, fractions will be very helpful.

•You can use fractions to divide cake, or candy, and you will need fractions to help figure out percents.

•Fractions are useful when you buy paint to make your house look nice and for figuring how much interest you will pay to the bank when you take a loan.

•Fractions may be a bit difficult to learn, but believe me, you will be happy that you spent the time.
