Student Relevance:

Content StandardsContent standards are interwoven and should be addressed throughout the year in as many different units and activities as possible in order to emphasize the natural connections that exist among mathematical topics.MGSE5.NF.1 Add and subtract fractions and mixed numbers with unlike denominators by finding a common denominator and equivalent fractions to produce like denominators.MGSE5.NF.2 Solve word problems involving addition and subtraction of fractions, including cases of unlike denominators (e.g., by using visual fraction models or equations to represent the problem). Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + ½ = 3/7, by observing that 3/7 < ½.MGSE5.NF.3 Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading

to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem. Example: 35 can be interpreted

as “3 divided by 5 and as 3 shared by 5”.MGSE5.NF.4 Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.

a. Apply and use understanding of multiplication to multiply a fraction or whole number by a fraction.

Examples: ab×q as

a. Interpret division of a unit fraction by a non-zero whole number, and compute such quotients.For example, create a story context for (1/3) ÷ 4, and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that (1/3) ÷ 4 = 1/12 because (1/12) × 4 = 1/3.b. Interpret division of a whole number by a unit fraction, and compute such quotients. For example, create a story context for 4 ÷ (1/5), and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that 4 ÷ (1/5) = 20 because 20 × (1/5) = 4.c. Solve real world problems involving division of unit fractions by non-zero whole numbers and division of whole numbers by unit fractions, e.g., by using visual fraction models and equations to represent the problem. For example, how much chocolate will each person get if 3 people share ½ lb of chocolate equally? How many 1/3-cup servings are 2 cups of raisins

1 Students able to multiply fractions in general can develop strategies to divide fractions in general, by reasoning about the relationship between multiplication and division. But division of a fraction by a fraction is not a requirement at this grade.MGSE5.MD.2 Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Use operations on fractions for this grade to solve problems involving information presented in line plots. For example, given different measurements of liquid in identical beakers, find the amount of liquid each beaker would contain if the total amount in all the beakers were redistributed equally.

defining the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each

part has size 1b . Recognize that a unit fraction

1b is

located 1b whole unit from 0 on the number line.

Represent a non-unit fraction ab on a number line

diagram by marking off a lengths of 1b (unit

fractions) from 0. Recognize that the resulting

interval has size ab and that its endpoint locates the

non-unit fraction ab on the number line.

Explain equivalence of fractions through reasoning with visual fraction models. Compare fractions by reasoning about their size.Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.Recognize and generate simple equivalent fractions with denominators of 2, 3, 4, 6, and 8, e.g., 12=2

4, 46=2

3. Explain why the fractions are

equivalent, e.g., by using a visual fraction model.

Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers.

Examples: Express 3 in the form 3 = 62 (3 wholes is

equal to six halves); recognize that 31 = 3; locate

44

and 1 at the same point of a number line diagram.

such as 12 . Recognize that comparisons are valid only

when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions.Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers.

unit fractions 1b .

Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.

Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8; 3/8 = 1/8 + 2/8; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.

Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

example, use a visual fraction model to represent 5/4 as the product 5 × (1/4), recording the conclusion by the equation 5/4 = 5 × (1/4).Understand a multiple of a/b as a multiple of 1/b, and use this understanding to multiply a fraction by a whole number. For example, use a visual fraction model to express 3 × (2/5) as 6 × (1/5), recognizing this product as 6/5. (In general, n × (a/b) = (n × a)/b.)

Solve word problems involving multiplication of a fraction by a whole number, e.g., by using visual fraction models and equations to represent the problem. For example, if each person at a party will eat 3/8 of a pound of roast beef, and there will be 5 people at the party, how many pounds of roast beef will be needed? Between what two whole numbers does your answer lie?

Understand decimal notation for fractions, and compare decimal fractions.

Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100.1 For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/100.

Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.

Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and

Adding, Subtracting, Multiplying and Dividing Fractions Instructional StrategiesAddition and SubtractionMGSE5.NF.1This standard builds on the work in 4th grade where students add fractions with like denominators. In 5th grade, the example provided in the standard has students find a common denominator by finding the product of both denominators. For 1/3 + 1/6, a common denominator is 18, which is the product of 3 and 6. This process should be introduced using visual fraction models (area models, number lines, etc.) to build understanding before moving into the standard algorithm.

Students should apply their understanding of equivalent fractions and their ability to rewrite fractions in an equivalent form to find common denominators. They should know that multiplying the denominators will always give a common denominator but may not result in the least common denominator.

MGSE5.NF.2This standard refers to number sense, which means students’ understanding of fractions as numbers that lie between whole numbers on a number line. Number sense in fractions also includes moving between decimals and fractions to find equivalents, also being able to use reasoning such as 7/8 is greater than 3/4 because 7/8 is missing only 1/8 and 3/4 is missing ¼, so7/8 is closer to a whole Also, students should use benchmark fractions to estimate and examine the reasonableness of their answers. An example of using a benchmark fraction is illustrated with comparing 5/8 and 6/10. Students should recognize that 5/8 is 1/8 larger than 1/2 (since 1/2 = 4/8) and 6/10 is 1/10 1/2 (since 1/2 = 5/10).

USING DIVISION TO MULTIPLY AND DIVIDE FRACTIONS.MGSE5.NF.3This standard calls for students to extend their work of partitioning a number line from third and fourth grade. Students need ample experiences to explore the concept that a fraction is a way to represent the division of two quantities. Students are expected to demonstrate their understanding using concrete materials, drawing models, and explaining their thinking when working with fractions in multiple contexts. They read 3/5 as “three fifths” and after many experiences with sharing problems, learn that 3/5 can also be interpreted as “3 divided by 5.”

MGSE5.NF.4 a.This standard references both the multiplication of a fraction by a whole number and the multiplication of two fractions.

MGSE5.NF.4bThis standard extends students’ work with area. In third grade students determine the area of rectangles and composite rectangles. In fourth grade students continue this work. The fifth grade standard calls students to continue the process of covering (with tiles). Grids (see picture) below can be used to support this work.

MGSE5.NF.5aThis standard calls for students to examine the magnitude of products in terms of the relationship between two types of problems. This extends the work with MGSE5.OA.1.

MGSE5.NF.5bThis standard asks students to examine how numbers change when we multiply by fractions. Students should have ample opportunities to examine both cases in the standard:a) when multiplying by a fraction greater than 1, the number increases andb) when multiplying by a fraction less the one, the number decreases. This standard should be explored and discussed while students are working with MGSE5.NF.4, and should not be taught in isolation.

This standard builds on all of the work done in this cluster. Students should be given ample opportunities to use various strategies to solve word problems involving the multiplication of a fraction by a mixed number. This standard could include fraction by a fraction, fraction by a mixed number or mixed number by a mixed number.

MGSE5.NF.7aThis standard asks students to work with story contexts where a unit fraction is divided by a non-zero whole number. Students should use various fraction models and reasoning about fractions.

Student 1

I know I need to find the value of the expression 1/8 ÷ 3, and I want to use a number line.

Student 2

I drew a rectangle and divided it into 8 columns to represent my 1/8. I shaded the first column. I then needed to divide the shaded region into 3 parts to represent sharing among 3 people. I shaded one-third of the first column even darker. The dark shade is 1/24 of the grid or 1/24 of the bag of pens.

Student 31/8 of a bag of pens divided by 3 people. I know that my answer will be less than 1/8 since I’m sharing 1/8 into 3 groups. I multiplied 8 by 3 and got 24, so my answer is 1/24 of the bag of pens. I know that my answer is correct because (1/24) 3 = 3/24 which equals 1/8.

MGSE5.NF.7bThis standard calls for students to create story contexts and visual fraction models for division situations where a whole number is being divided by a unit fraction.

Student

The bowl holds 5 Liters of water. If we use a scoop that holds 1/6 of a Liter, how many scoops will we need in order to fill the entire bowl?

I created 5 boxes. Each box represents 1 Liter of water. I then divided each box into sixths to represent the size of the scoop. My answer is the number of small boxes, which is 30. That makes sense since 6 5 = 30.

1 = 1/6 + 1/6 + 1/6 + 1/6 + 1/6 a whole has 6/6 so five wholes would be 6/6 + 6/6 + 6/6 + 6/6 + 6/6 =30/6.

MGSE5.NF.7cThis standard extends students’ work from other standards in MGSE5.NF.7. Student should continue to use visual fraction models and reasoning to solve these real-world problems.

Adding, Subtracting, Multiplying and Dividing with Fractions MisconceptionsMGSE5.NF.1, MGSE5.NF.2Students often mix models when adding, subtracting or comparing fractions. Students will use a circle for thirds and a rectangle for fourths when comparing fractions with thirds and fourths. Remind students that the representations need to be from the same whole models with the same shape and size.

MGSE5.NF.3-7 – Students may believe that multiplication always results in a larger number. Using models when multiplying with fractions will enable students to see that he results will be smaller. Additionally, students may believe that division always results in a smaller number. Using models when dividing with fractions will enable students to see that the results will be larger.
