**StAIR project by:**Dana Collett CEP 811 Created for 4th-6th grade Fraction Frenzy**Introduction**• Welcome! I have you are ready to learn. • Supplies • Paper and pencil • At the end there are extra resources, please take the time to look at them. • For this powerpoint, use the space bar at each slide until you see and then use the arrows at the bottom on the page.**Objectives and Standards**• Understand the concept of a fraction and the vocabulary • Generate equivalent fractions • Convert improper fractions into mixed numbers • Add and subtract fractions with like and unlike denominators • 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?**• Check out this Scholastic tutorial on fractions: • Scholastic Fractions Studyjams • 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 • True or False: Both of these pictures show ¾ ? TRUE FALSE**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. • 2nd 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 3⅙)**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 • Use the website above to create equivalent fractions. • Still want more? Go the PBS website and match equivalent fractions. • http://pbskids.org/cyberchase/games/equivalentfractions/index.html Which fraction is equivalent to ½? 1/3 3/6 5/6 8/12**Oh no **• What went wrong? • Go back a couple slides and look at the pictures that shows equivalent fractions for ½ . • 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. • When you are finished, continue on, to the interactive practice and even use the fraction bars to help you! • ⅖⅘ • ⅞ ⅜**You Got It**Superb Excellent Wonderful**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**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.**Storybird**• Take a look at how digital storytelling can teach you about fractions • You Use Fractions Everyday • Adventures in Understanding Fractions • How Peter Learned Fractions**Fraction Online Games**• Here’s a challenge- this site wants you to make ½ in 13 different ways! • 13 ways looking at a half • Make different pizza according to client’s orders • Tony's Pizza Shop • Lkdfajsdkl • Check out these games as well • Gamequarium • Visual Fractions**Resources**Take a look at the various resources below.
