Kentucky Academic Standards
Numbers and Operations—Fractions
Cluster: Extend understanding of fraction equivalence and ordering.
KY.4.NF.1. Understand and generate equivalent fractions. (MP.4, MP.7, MP.8)
KY.4.NF.1.a. Use visual fraction models to recognize and generate equivalent fractions that have different numerators/denominators even though they are the same size.
KY.4.NF.1.b. Explain why a fraction a/b is equivalent to a fraction (n×a)/(n×b).
KY.4.NF.2. Compare two fractions with different numerators and different denominators using the symbols <, =, or >. Recognize comparisons are valid only when the two fractions refer to the same whole. Justify the conclusions. (MP.2, MP.3)
Cluster: Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers.
KY.4.NF.4. Apply and extend previous understandings of multiplication to multiply a fraction by a whole number. (MP.5, MP.8)
KY.4.NF.4.a. Understand a fraction a/b as a multiple of 1/b.
