Standard: 4.NF.B.3.B
Domain: Number & Operations - Fractions
Theme: Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers
Description: 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.
