Students add and subtract fractions with like denominators, including mixed numbers and fractions greater than one. They apply these operations to solve real-world problems. Denominators are limited to 2, 3, 4, 5, 6, 8, 10, 12, 16, and 100. Problems include creating real-world situations based on an equation or by representing a real-world problem with a visual model or equation. Fractions within problems must reference the same whole. Students are expected to use word form, manipulatives, drawings, and number lines when adding and subtracting fractions. It is not necessary for students to simplify fractions.
