Introduction  Welcome! I have you are ready to learn.  Supplies Paper and pencil  At the end there are extra resources, pleasetake the time to look at them.  For this powerpoint, use the space bar ateach slide until you see and thenuse the arrows at the bottom on the page.

Objectives and Standards  Understand the concept of a fraction and thevocabulary  Generate equivalent fractions  Convert improper fractions into mixednumbers  Add and subtract fractions with like and unlikedenominators  Compare fractions using, and =

Table of Contents  Understanding this PowerPoint  What are fractions  Vocabulary  Equivalent Fractions  Compare Fractions  Improper fractions and Mixed Numbers  Add and Subtract Fractions

How to navigate....  You can start at the beginning- hit the space bar to help you navigate through the slide and then......  When you see the equal sign at the bottom of the page- that is your signal to click on the “Next Slide” button.  OR  The stars on the Table of Contents slide will lead you to that particular slide.  The buttons on the bottom  will take you to the NEXT page  will take you to the PREVIOUS page The math operations swirl in the middle will take you to the table of contents- just click on it!  Turn your volume up and Enjoy

What are Fractions? CCheck out this Scholastic tutorial on fractions: Scholastic Fractions Studyjams WWant to do more? Click on the link below to take you to another game. http://www.vectorkids. com/vkfractions.htm  A fraction is a number that names part of a whole. A fraction MUST be broken into EQUAL pieces Can you think of things in our everyday life that contain fractions?

Show Me Fractions  ⅓ can look like this:  OR this:  Visualize Create and Visualize your own fractions Create and Visualize your own fractions  True or False: Both of these pictures show ¾ ? TRUEFALS E

You Did it! Way to go!  In both pictures, the bar is divided into 4 equal parts and three parts are shaded. Even though they are not the same three parts, both still represent ¾.

Try Again  Hint: Think about what the numerator and denominator are telling you.  2 nd Hint: ¾ means there are 3 shaded parts out of 4 equal parts

Vocabulary  Fraction Equal parts of a whole  Numerator The number ABOVE the fraction line that tells how many parts of the whole are being considered  Denominator The number BELOW the fraction line that tells how many EQUAL parts are in the whole  Equivalent fraction Fractions that name the same amount  Improper fraction When the numerator is greater than the denominator (e.g. 11/6)  Mixed number A whole number and a fraction (e.g. 2½ or 3 ⅙ )

Let’s Review..... Fill in the blank using the vocabulary words in the word bank below. (Write your answers on your paper)  12/3 is an example of an ____________________.  In ⅗ the number 3 is the ___________________.  ½ and 4/8 are ___________________.  ⅘ is a _____________. It means that there are 5 equal pieces in the whole and 4 are being considered.  A ______________ is a whole number and a fraction, like 2⅞  The _______ ______ tells you how many equal parts are in the whole. Equivalent Fractions Numerator Denominator Improper Fraction Fraction Mixed Number

Let’s Review (Answers)  12/3 is an example of an improper fraction.  In ⅗ the number 3 is the numerator.  ½ and 4/8 are equivalent fractions.  ⅘ is a fraction. It means that there are 5 equal pieces in the whole and 4 are being considered.  A mixed number is a whole number and a fraction, like 2⅞  The denominator tells you how many equal parts are in the whole.

Equivalent Fractions  Equivalent fractions are fractions that name the same amount. Take a look at the picture. 1/2 = 2/4 1/2 = 3/6 5/10=4/8 Notice that all the fraction bars line up and they are all equivalent.

Equivalent Fraction Review  http://www.abcya.com/ fraction_tiles.htm http://www.abcya.com/ fraction_tiles.htm  Use the website above to create equivalent fractions.  Still want more? Go the PBS website and match equivalent fractions. http://pbskids.org/cyberc hase/games/equivalentf ractions/index.html http://pbskids.org/cyberc hase/games/equivalentf ractions/index.html Which fraction is equivalent to ½? 1/35/68/123/6

Oh no  WWhat went wrong? GGo back a couple slides and look at the pictures that shows equivalent fractions for ½. SStill Need Help? Take a look at this: http://www.abcya.com/fraction_tiles.htm

YES!!!  1/2 is EQUIVALENT to 3/6

Compare Fractions  Click on this tutorial to learn about how to compare fractions. Click on this tutorial  When you are finished, continue on, to the interactive practice and even use the fraction bars to help you!interactive practice fraction bars  ⅖ ⅘  ⅞ ⅜

Let’s Try Again Grab some fraction bars if you are having difficulty! Hit the Previous page button to go back to the slide.

Improper Fractions and Mixed Numbers Review  Mixed Numbers 2 ½ or 3 ⅚ are both examples of mixed numbers. You can turn a mixed number into a fraction by multiplying and adding.  Mixed Number into Fraction Multiply the whole number and the denominator. Then, add the numerator. The denominator STAYS the same! Go to the next slide to check it out.  Improper Fractions Are “top heavy” The numerator is greater than the denominator.  Improper Fractions to Mixed Numbers Look at the fraction as a division sign. In the example, you would do 7 divided by 5. The quotient is the whole number, the remainder is the numerator and the denominator stays the SAME.

Mixed Numbers to Improper fractions  http://www.coolmath.com/prealgebra/01- fractions/fractions-07-improper-03.htm http://www.coolmath.com/prealgebra/01- fractions/fractions-07-improper-03.htm

Try Some~  Turn these improper fractions into mixed numbers 1) 11/3 2) 5/6  Turn these mixed numbers into improper fractions 3) 2 ⅓ 4) 1 ⅝ Don’t hit this until you have FINISHED all the problems

Try Some Answers  Turn these improper fractions into mixed numbers 1) 11/3  11÷ 3 = 3 r2  3 2/3 2) 5/6  5÷6= 1r1  1 ⅙  Turn these mixed numbers into improper fractions 3) 2 ⅓  2 x3 +1 = 7/3 4) 1 ⅝  1x8 +5 = 13/8

Add and Subtract Fractions with Like Denominators  When adding or subtracting fractions with LIKE denominators, you add the numerators ONLY and keep the denominator the same.  3 – 1 = 3 – 1 = 2 4 4 4 4

Think about It On your sheet of paper, write the answers to the following questions. Make sure to write in complete sentences.  Name 3 things that require the use of fractions?  You are baking a cake, it calls for ¾ cup of sugar. You do not have a ¾ cup, how are you going to measure out the correct amount of sugar?  How are fractions related to measurement?  Write 2 things you learned and 2 things you still need to work on.
