This Instructional Activity is a part of the Lesson 10, Unit 4, Grade 6. In this activity, students use tape diagrams and the meanings of division to divide a number by unit fractions. They do this as a first step toward generalizing the reasoning for dividing any two fractions. Later, students put together those results to see that dividing by a fraction c/d is equivalent to dividing by c and multiplying by d.
