Multiply by Fractions

Grade: 4th Grade
Standard:

CC.2.1.4.C.2

Description:

Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers.

Standard:

M04.A-F.2.1.5

Description:

Multiply a whole number by a unit fraction (denominators limited to 2, 3, 4, 5, 6, 8, 10, 12, and 100 and final answers do not need to be simplified or written as a mixed number).

Standard:

M04.A-F.2.1.6

Description:

Multiply a whole number by a non-unit fraction (denominators limited to 2, 3, 4, 5, 6, 8, 10, 12, and 100 and final answers do not need to be simplified or written as a mixed number).

Standard:

Math.4.NF.4a or 4.NF.B.4.A

Description:

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).

Standard:

Math.4.NF.4b or 4.NF.B.4.B

Description:

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.)
