Lesson Narrative
In the previous lesson, students solved problems involving division of a whole number by a unit fraction. In this lesson, students continue to find quotients of a whole number by a unit fraction. In this lesson, students find the value of expressions without being provided a tape diagram. The numbers are not large, so they may draw a diagram if it is helpful. In the second activity, students look simultaneously at expressions involving quotients of a whole number by a fraction and quotients of a fraction by a whole number.
- Action and Expression
None
- Compare and contrast (orally and in writing) diagrams and equations that represent dividing a whole number by a fraction.
- Generalize (orally and in writing) that $A \div \frac{1}{D} = A \times D$.
- Resolvamos problemas dividiendo un número entero entre una fracción unitaria.

Teacher Reflection Questions
Reflect on times you observed students listening to one another’s ideas today in class. What norms would help each student better attend to their classmates' ideas in future lessons?
