2 CCSS: 6.NS. Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem. Objective: SWBAT solve division word problems with fractions by locating the divisor and dividend. LEQ: How do I explain the algorithm and use it to solve division word problems?

5 Previously we... started exploring with division with fractions. To review, we are going to watch a clip that will remind us of what we learned and also explain why we flip our second fraction. **Be ready to explain why changing the sign and flipping the second fraction works when dividing fractions? D I V I D I NG F R A C T I O N S What is the one thing we should remember to do when we divide fractions? Can anyone tell me why how does changing the sign and flipping the sign "work" when dividing fractions? 2 2 = 6 2 x 2 = 2 2 = 6 **dividing is multiplying by the reciprocal(flipping)

6 Teacher Input Word problems can be tricky sometimes as they give you the information. Use your RUBIES strategy to break down the problem, but you must also identify your dividend and your divisor. Ask the question, "What is being divided up?" or "What is the total amount given?" For example: Critical Thinking Questions: What is being divided up?" or "What is the total amount given?" What is being made and how much ribbon does it take? What is written first? The dividend or the divisor? What steps are needed to compute the answer?

7 Modeling ) Critical Thinking Questions: What is being divided up?" or "What is the total amount given?" What is being made and how much ribbon does it take? What is written first? The dividend or the divisor? What steps are needed to compute the answer? Pencils down, look and listen!!! Model 2) 3 The serving size for a toddler s daily vitamin C is 4 cup of orange juice. If there are 2 4 cups of orange juice, how many servings of vitamin C are there for a toddler? Model 3. Allen is building birdhouses that require ft long boards. How many pieces that are exactly 2 ft long can be made from a board that is ft long? NOW... copy on the given paper to glue in your notebook!!

8 Collaborative Practice Critical Thinking Questions: What is being divided up?" or "What is the total amount given?" What is being made and how much ribbon does it take? What is written first? The dividend or the divisor? What steps are needed to compute the answer? 3 8 Molly purchased cups of strawberries. She eats 4 in a serving. How many servings did Molly purchase? Try a model if you finish early X 4 Computation Answers = 44 = 8 = Modeling /2

9 . Independent Practice... Critical Thinking Questions: What is being divided up?" or "What is the total amount given?" What is being made and how much ribbon does it take? What is written first? The dividend or the divisor? What steps are needed to compute the answer? Andy wants to buy 3 /3 cups of cashews. There are 5/6 cup of cashews in each package. How many packages of cashews should Andy buy? 4 packages ½ of a gallon of milk is being poured in to smaller containers that each hold /3 of a gallon of milk. How many small containers can be filled? /2 containers It requires /4 of a credit to play a video game for one minute. Emma has 7/8 credits. Can she play for more or less than one minute?
