|
Decompose a fraction into a sum of fractions with the same denominator in more than one way (e.g., 3/8 = 1/8 + 1/8 + 1/8; 3/8 = 1/8 + 2/8; 21/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8), recording each decomposition by an equation. Justify
decompositions by using a visual fraction model. |

Add and subtract fractions and mixed numbers with like denominators using fraction equivalence, properties of
operations, and the relationship between addition and subtraction. |
Arizona Academic Standards:
4.NF.B.3c
|
Add and subtract mixed numbers with like denominators (e.g., by using properties of operations and the relationship between addition and subtraction and/or by replacing each mixed number with an equivalent fraction). |
