This Instructional Activity is a part of the Lesson 5, Unit 2, Grade 6. Plastic fraction tile sets should be available for students who prefer a concrete model to handle. These are also useful for students who have difficulty making accurate sketches to show their work. In this example, students reason abstractly and quantitatively. They make sense of quantities and their relationships in problems and understand "how many" as it pertains to the divisor when finding the quotients of fractions. Encourage students to work each step in order.
