Number and Operations—FractionsBuild fractions from unit fractions by applying and extending previous understandings of operations on whole numbers.3Understand a fraction a/b with a > 1 as a sum of fractions 1/b.bDecompose 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
