Title: FUN WITH FRACTIONS!


1
FUN WITH FRACTIONS!
  • A Study Guide
  • and
  • Review Game

2
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.

3
Heres a Hint
  • 24

The number in the NORTH is the Numerator!
The number that is DOWN is the Denominator!
4
Part of a whole
  • 3 is yellow
  • 8

Part of a set
4 of the set are pears5

Finding Equivalent Fractions
  • EQUivALent means EQUAL!
  • 3 is EQUivALent to 16

10
Heres a Hint
  • To find equivalent fractionsLOOK FOR A PATTERN

Heres Another Hint
  • To find equivalent fractionsUSE BOTTOMS UP!

14
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
  • Draw a picture
  • Use Bottoms Up
  • Use Fraction Fringe

15
Ordering Fractions withDrawing A Picture
  •   1 1 1
  • 3 6 9










Least to greatest    1 1 1 9
6 3

Ordering Fractions with Bottoms Up
  •   1 1 1
  • 3 6 9
  • Compare 1 and 1 3 6
  • Compare 1 and 1 3 9
  • Compare 1 and 1 6 9

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 3
19
Finding Parts of a Set
  • When a picture is not given, you have two
    choices
  • Draw a picture and solve!
  • Do the math!

20
8 times what 64?
?
  • 1 Of 64
  • 8

21
Mixed Numbers
  • A mixed number is a whole number and a fraction
    combined

22
Mixed Numbers
  • Count the WHOLEs first
  • Then find the FRACTIONal part

23
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.
