What are Fractions? CCheck out this Scholastic tutorial on fractions: Scholastic Fractions Studyjams WWant 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?

8
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

9
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.

10
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

11
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 )

12
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

13
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.

14
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.

15
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

16
Oh no WWhat went wrong? GGo back a couple slides and look at the pictures that shows equivalent fractions for ½. SStill Need Help? Take a look at this: http://www.abcya.com/fraction_tiles.htm

17
YES!!! 1/2 is EQUIVALENT to 3/6

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.

23
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

24
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

25
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

26
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.
