# Math Common Core Standards K 5 Grade 4 Number and Operations Fractions

Grade 4 (4.NF.A.1)Extend understanding of fraction equivalence and ordering.
Ages 8 - 9

## Fraction patterns

SUPPORTS 4.NF.A.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.  • Calendar

## Fraction Pies

SUPPORTS 4.NF.B.3b: Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.  • Calendar
