21.NF.3 recognize that a fraction a/b with a > 1 as a sum of fractions 1/b
22.NF.3_a. model and explain addition and subtraction of fractions as joining and separating parts referring to the same whole
23.NF.3_b. decompose a fraction, by using a visual fraction model, into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation and justify reasoning using visual fraction models (e.g., 3/8 = 1/8 + 1/8 + 1/8; 3/8 = 1/8 + 2/8; 2 1/8 = 1 + 1 + 1/8; 8/8 = 7/8 + 1/8)
24.NF.3_c. add and subtract mixed numbers with like denominators (e.g., by replacing each mixed number with an equivalent fraction
and/or by using properties of operations and the relationship between addition and subtraction)
25.NF.3_d. solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators by using visual fraction models and equations to represent the problem.
