# Understanding, Modeling and Creating Equivalent Fractions

Grade 4 / Math / Fractions
CCSS: Math.4.NF.A.1

Common Core State Standards

 Math Math 4 Grade 4 NF Number & Operations--Fractions A Extend understanding of fraction equivalence and ordering 1 Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, 100.
