CARECurriculum Assessment Remediation Enrichment6th gradeMathematics CARE Package for Test #3Domain The Number SystemCluster Apply and extend previous understandings of multiplication and division to divide fractionsby fractions.Standards MAFS.6.NS.1.1 Interpret and compute quotients of fractions, and solve word problemsinvolving division of fractions by fractions, e.g., by using visual fraction models andequations to represent the problem. For example, create a story context for (2/3) (3/4) anduse a visual fraction model to show the quotient; use the relationship betweenmultiplication and division to explain that (2/3) (3/4) 8/9 because 3/4 of 8/9 is 2/3. (Ingeneral, (a/b) (c/d) ad/bc.) How much chocolate will each person get if 3 people share1/2 lb of chocolate equally? How many 3/4-cup servings are in 2/3 of a cup of yogurt? Howwide is a rectangular strip of land with length 3/4 mi and area 1/2 square mi?MAFS.6.NS.2.4 Find the greatest common factor of two whole numbers less than or equalto 100 and the least common multiple of two whole numbers less than or equal to 12. Usethe distributive property to express a sum of two whole numbers 1–100 with a commonfactor as a multiple of a sum of two whole numbers with no common factor. For example,express 36 8 as 4 (9 2).CURRICULUMStudent Problem-Solving (SPS)The SPS site provides interactive activities for students. This wiki is a work in progress and will be updated regularly.Implementation SuggestionStudents may work independently or in small groups of 2-3 to complete the task (ESE Strategy – Provide peerassistance; ESOL E4 – Peer Pair). Allow 15-20 minutes to complete this task. Students can meet with othergroups to share their results. (ESOL E6 – Think/Pair/Share). Then, review as a class-wide discussion.DifferentiationSome students may benefit from working with a partner to complete the task. Encourage students who completed theperformance task early to share their models and how they arrived at the solutions with a partner. Some students maybenefit from using manipulatives, such as fraction bars.Mathematical Practice #1- Make sense of problems and persevere in solving them.Students make sense of and solve a fraction division problem with a remainder; they asked to make a diagram torepresent the problem, and relate this representation to the context of the problem. Students are asked to explain howthey check their answers to the problems using a different method.Mathematical Practice #2- Reason abstractly and quantitativelyStudents are reasoning quantitatively by creating a coherent representation of the problem; considering the unitsinvolved; and attending to the meaning of quantities, and not just how to compute them.

Performance Task(MAFS.6.NS.1.1)SHARE MY CANDYJason hascandy bars. He wants to share the candy bars with his friends. He gives asmany friends as possible of a candy bar. He keeps the rest for himself.PART A: How many friends can he give of a candy bar to? Draw a model to solve theproblem. Write your answer in a complete sentence.ANSWER SENTENCE: He can give 4 friends ¾ of a candy bar.PART B: How much of the candy bar will Jason keep for himself? Show your work andwrite your answer in a complete sentence.From the picture above, Jason has or left. That is not enough to share with another friendbecause it is less than .ANSWER SENTENCE: Jason has or left.Adapted from “Share My Candy” NYC Department of Education http://schools.nyc.gov

PART C: Explain your reasoning for parts A and B.Jason wants to sharecandy bars with his friends. I can drewcandy bars and then split eachwhole one into fourths because he wants to give three-fourths to each friend.PART D: Use division to model the problem. Show your work.He can give ¾ of the candy bar to 4 friends. He will have some left over.PART E: Explain how your answer from PART D is equivalent to your answers fromPARTS A and B.4 is the number of friends he can give three-fourths of the candy bar to. In Part B, I found that hehad ½ of a candy bar left. In part D, there is 2/3 left. The fraction he gives to each person is ¾and 2/3 of thatgroup is ½.2/3 of 3/43/4Adapted from “Share My Candy” NYC Department of Education http://schools.nyc.gov

REMEDIATION / RETEACHAcademic Vocabulary: Activate prior knowledge (ESE Strategy – Pre-teach Vocabulary;ESOL G1-Activating Prior Knowledge) by reviewing key terms and concepts.fraction, numerator, denominator, greatest common factor (GCF), least common multiple(LCM), quotient, remainder, divisor, dividend, mixed number, reciprocalSample Questions that Elicit Thinking1) How does division of fractions relate to multiplication of fractions?2) Why is the quotient greater than the dividend when dividing by a value less than one?3) Why does the process of invert and multiply work when dividing fractions?4) When I divide a fraction by a fraction what do the dividend, quotient and divisor represent?Think, Pair, ShareHave students jot down their own responses to questions, then discuss with a partner, and thendiscuss as a whole class. (ESOL E6 Think/Pair/Share)Go over academic vocabulary and/or use vocabulary graphic organizer. (ESOL D9 VocabularyBanks)

Common Misconceptions:Some students may find it difficult to understand that dividing by a number less than one results ina quotient that is greater than the dividend. Using models and helping them interpret what thequotient represents can help clear up this misunderstanding. Computation with fractions is bestunderstood when it builds upon the familiar understandings of whole numbers and is paired withvisual representations. Solve a simpler problem with whole numbers, and then use the same steps tosolve a fraction divided by a fraction. Looking at the problem through the lens of “How manygroups?” or “How many in each group?” helps visualize what is being sought.Most of students’ fraction modeling experience has probably been with dividing one whole intofractional parts. When dividing fractions, they are expected to partition fractions and mixednumbers into groups of fractional size.ResourcesModels of Fraction DivisionVisual FractionsDivide FractionsDescriptionStudents are asked to explain the relationship between afraction division word problem and either a visual modelor an equation.Divide Fractions is an interactive website where studentsare presented with a model of fraction division and areasked to identify the dividend, the divisor, and thequotient. All quotients will be a whole number between 1and 12.
