Standard Identifier:

Content Area:
Mathematics
Grade:
4
Domain:
Number and Operations—Fractions
Cluster:
Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers.
Standard:
Apply and extend previous understandings of multiplication to multiply a fraction by a whole number. 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.)
