Eureka Math
5th Grade
Module 1
Lesson 15
At the request of elementary teachers, a team of Bethel & Sumner educators met as a committee to create Eureka slideshow presentations. These presentations are not meant as a script, nor are they required to be used. Please customize as needed. Thank you to the many educators who contributed to this project!
Directions for customizing presentations are available on the next slide.

Application Problem
Jose bought a bag of 6 oranges for $2.82. He also bought 5 pineapples. He gave the cashier $20 and received $1.43 change. How much did each pineapple cost?

What do you notice about this division problem?
If we divide this out, we will end up having a remainder. We used to call that R 1. We have learned a new division skill that lets us do something else with the remainder. What is it?
If we unbundle ones, we can rename them as tenths. Tenths can be renamed as hundredths...this allows us to divide the remainder!
For the next four problems, work with a partner. One of you will use the place value chart, the other will use the standard algorithm. Compare your work as you go along, making sure you are getting the same answers.

Problem Set
Debrief
In Problems 1(a) and 1(b), which division strategy did you find more efficient—drawing place value disks or using the algorithm?
How are Problems 2(c) and 2(f) different from the others? Will a whole number divided by a whole number always result in a whole number?
Explain why these problems resulted in a decimal quotient.
Take out the Problem Set from Lesson 14. Compare and contrast the first page of each assignment. Talk about what you notice.
Take a look at Problem 2(f). What was different about how you solved this problem?
When you solved Problem 4, what did you notice about the units used to measure the juice? (Students may not have recognized that the orange juice was measured in milliliters.) How do we proceed if we have unlike units?
