# Lesson 6

What’s the Quotient?

### Lesson Purpose

The purpose of this lesson is to reinforce students’ understanding of division algorithms that use partial quotients and build their fluency in using it to divide multi-digit numbers by a single-digit divisor. Students also consider different strategies for dividing and their merits.

### Lesson Narrative

In an earlier unit, students learned to use partial quotients to divide whole numbers up to four digits by single-digit divisors. In this lesson, students deepen their understanding of algorithms that use partial quotients and continue to build their fluency with multiplication and division. Students also analyze different ways to divide whole numbers and consider how to improve their efficiency.

If students need additional support with the concepts in this lesson, refer back to Unit 6, Section C in the curriculum materials.
