Standard Identifier: 5.NF.5.b

Grade: 5
Domain: Number and Operations—Fractions

Cluster:
Apply and extend previous understandings of multiplication and division to multiply and divide fractions.

Standard:
Interpret multiplication as scaling (resizing), by: Explaining why multiplying a given number by a fraction greater than 1 results in a product greater than the given number (recognizing multiplication by whole numbers greater than 1 as a familiar case); explaining why multiplying a given number by a fraction less than 1 results in a product smaller than the given number; and relating the principle of fraction equivalence a/b = (n × a)/(n × b) to the effect of multiplying a/b by 1.

Standard Identifier: 5.NF.6

Grade: 5
Domain: Number and Operations—Fractions

Cluster:
Apply and extend previous understandings of multiplication and division to multiply and divide fractions.

Standard:
Solve real-world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem.

Standard Identifier: 5.NF.7.a

Grade: 5
Domain: Number and Operations—Fractions

Cluster:
Apply and extend previous understandings of multiplication and division to multiply and divide fractions.

Standard:
Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions. 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.

Footnote:
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.

Standard Identifier: 5.NF.7.b

Grade: 5
Domain: Number and Operations—Fractions

Cluster:
Apply and extend previous understandings of multiplication and division to multiply and divide fractions.

Standard:
Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions. 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.

Standard Identifier: 5.NF.7.c

Grade: 5
Domain: Number and Operations—Fractions

Cluster:
Apply and extend previous understandings of multiplication and division to multiply and divide fractions.

Standard:
Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions. 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 1/2 lb of chocolate equally? How many 1/3-cup servings are in 2 cups of raisins?

Standard Identifier: 6.NS.1

Grade: 6
Domain: The Number System

Cluster:
Apply and extend previous understandings of multiplication and division to divide fractions by fractions.

Standard:
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. For example, create a story context for (2/3) ÷ (3/4) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (2/3) ÷ (3/4) = 8/9 because 3/4 of 8/9 is 2/3. (In general, (a/b) ÷ (c/d) = ad/bc.) How much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 3/4-cup servings are in 2/3 of a cup of yogurt? How wide is a rectangular strip of land with length 3/4 mi and area 1/2 square mi?

Standard Identifier: 6.NS.2

Grade: 6
Domain: The Number System

Cluster:
Compute fluently with multi-digit numbers and find common factors and multiples.

Standard:
Fluently divide multi-digit numbers using the standard algorithm.

Standard Identifier: 6.NS.3

Grade: 6
Domain: The Number System

Cluster:
Compute fluently with multi-digit numbers and find common factors and multiples.

Standard:
Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.

Standard Identifier: 6.NS.4

Grade: 6
Domain: The Number System

Cluster:
Compute fluently with multi-digit numbers and find common factors and multiples.

Standard:
Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2).

Standard Identifier: 6.NS.5

Grade: 6
Domain: The Number System

Cluster:
Apply and extend previous understandings of numbers to the system of rational numbers.

Standard:
Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.
