Unit 8, Lesson 4
Volvamos a la división
Grado 5
Preparation
Lesson Narrative
In previous units, students learned how to find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors. They used strategies based on place value, properties of operations, and the relationship between multiplication and division. In this lesson, students apply these understandings as they decide if a quotient is reasonable and write division expressions for a given quotient. If students need additional support with the concepts in this lesson, refer back to Unit 4, Section B in the curriculum materials.
- Action and Expression
None
- Estimate and calculate the quotient of multi-digit whole numbers.
- Explain (orally and in writing) strategies for finding different pairs of numbers with the same given quotient.
- Estimemos y dividamos.

In tomorrow’s lesson, students revisit an algorithm for division that records partial-quotients. How did the mathematics in today’s lesson prepare students for using the partial-quotients algorithm?
