Unit 4, Lesson 10
Different Partial Quotients
Grade 5
Preparation
Lesson Purpose
The purpose of this lesson is for students to use place-value understanding and the relationship between multiplication and division to divide multi-digit numbers.
Lesson Narrative
In the previous lesson, students found quotients in a way that makes sense to them. In this lesson, students consider notation to record a partial-quotients strategy, which they have used with one-digit divisors in a prior grade. Students use the notation to record how dividends can be decomposed in different ways to make different partial quotients. Students consider more efficient ways to make partial quotients based on place-value understanding and calculations they are able to do mentally.
- Action and Expression
None
- Determine how to decompose the quotient that results from dividing a three-digit number by a two-digit number into smaller quotients.
- Identify and interpret (orally) expressions that show partial quotients for dividing a three-digit number by a two-digit number.
- Let’s use what we know about multiplication and place value to find quotients.
Required Preparation
Activity 1
- Create a set of cards from the blackline master for each group of 2 students.
