Alabama Course of Study Standards:
16.a
|
Model and explain how a non-unit fraction can be represented by a whole number times the unit fraction.
Example: 9/8 = 9 × 1/8 |
Arizona Academic Standards:
4.NF.B.4a
|
Understand a fraction a/b as a multiple of 1/b. In general, a/b = a × 1/b. |
Common Core State Standards:
Math.4.NF.4a or 4.NF.B.4.A
Kentucky Academic Standards (KAS):
4.NF.4.a
Mississippi College- and Career-Readiness Standards:
4.NF.4a
|
Understand a fraction a/b as a multiple of 1/b. For 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). |
North Carolina - Standard Course of Study:
4.NF.4.a
|
Model and explain how fractions can be represented by multiplying a whole number by a unit fraction, using this understanding to multiply a whole number by any fraction less than one. |
New York State Next Generation Learning Standards:
4.NF.4.a
|
Understand a fraction a/b as a multiple of 1/b.
e.g., Use a visual fraction model to represent 5/4 as the product 5 × 1/4, recording the conclusion with the equation 5/4 = 5 × 1/4. |
Ohio's Learning Standards:
4.NF.4.a
|
Understand a fraction a/b as a multiple of 1/b. For 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) or 5/4 = (1/4) + (1/4) + (1/4) + (1/4) + (1/4). |
Wisconsin Academic Standards:
4.NF.B.4.a
|
Understand a fraction as a group of unit fractions or as a multiple of a unit fraction.
For example, 5/4 can be represented visually as 5 groups of 1/4, as a sum of unit fractions 1/4 + 1/4 + 1/4 + 1/4 + 1/4, or as a multiple of a unit fraction 5 × 1/4. |
Alabama Course of Study Standards:
16.b
|
Extend previous understanding of multiplication to multiply a whole number times any fraction less than one.
Example: 4 × 2/3 = (4 × 2)/3 = 8/3 |
Arizona Academic Standards:
4.NF.B.4b
|
Understand a multiple of a/b as a multiple of 1/b, and use this understanding to multiply a whole
number by a fraction. In general, n × a/b = (n × a)/b. |
Common Core State Standards:
Math.4.NF.4b or 4.NF.B.4.B
Kentucky Academic Standards (KAS):
4.NF.4.b
Mississippi College- and Career-Readiness Standards:
4.NF.4b
|
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.) |
North Carolina - Standard Course of Study:
4.NF.4.b
|
Solve word problems involving multiplication of a fraction by a whole number. |
New York State Next Generation Learning Standards:
4.NF.4.b
|
Understand a multiple of a/b as a multiple of 1/b, and use this understanding to multiply a whole number by a fraction.
e.g., 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. |
Ohio's Learning Standards:
4.NF.4.b
|
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.) |
Tennessee Academic Standards:
4.NF.B.4.b
|
Understand a multiple of a/b as a multiple of 1/b and use this understanding to multiply a whole number by a fraction. 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 = (n × a) × 1/b.) |
Wisconsin Academic Standards:
4.NF.B.4.b
|
Represent a whole number times a non-unit fraction (e.g., 3 × 2/5) using visual fraction models and understand this as combining equal groups of the non-unit fraction (3 groups
of 2/5) and as a collection of unit fractions (6 groups of 1/5), recognizing this product as 6/5. |
