Students add and subtract fractions with unlike denominators, including mixed numbers and fractions greater than one, and they apply these operations to solve real-world problems. Instruction includes the use of estimation, manipulatives, visual models, and the properties of operations. When finding common denominators, students apply their understanding of factors up to 12 and their multiples.

B.E.S.T. Benchmarks:

• MA.5.FR.2.1 Add and subtract fractions with unlike denominators, including mixed numbers and fractions greater than 1, with procedural reliability.
• MA.5.AR.1.2 Solve real-world problems involving the addition, subtraction, or multiplication of fractions, including mixed numbers and fractions greater than 1.
