In this lesson, students continue understanding division of fractions by dividing a unit fraction by a whole number. They use tape diagrams to model their thinking before writing an expression. For example, they determine how many pans each friend will receive if 3 friends are sharing a 1/2 pan of brownies. Then, after creating several division sentences, they discuss the relationship of each quotient to the division expression. Finally, they check their work with a multiplication sentence.
