Application Problem
The area of a vegetable garden is 200 ft2. The width is 10 ft. What’s the length of the vegetable garden?
Note: This problem provides a nice opportunity to quickly address area concepts and division by a power of ten, allowing for a smooth transition into the day’s Concept Development. While solving, students should be encouraged to draw a picture of a rectangle to support their work.
Concept Development
Problem 1: 420 ÷ 10
Problem 2: 1,600 ÷ 100
Problem 3: 24,000 ÷ 600
Problem 4: 180,000 ÷ 9,000
Grade 5 Module 2 Lesson 16 Problem Set
- Divide. Draw number disks to show your thinking for (a) and (c). You may draw disks on your personal white board to solve the others if necessary.
a. 500 ÷ 10
c. 12,000 ÷ 100 - Divide.
b. 12,000 ÷ 300
e. 560,000 ÷ 700 - The floor of a rectangular banquet hall has an area of 3,600 m2. The length is 90 m.
a. What is the width of the banquet hall?
b. A square banquet hall has the same area. What is its length?
c. A third rectangular banquet hall has a perimeter of 3,600 m. What is the width if the length is 5 times the width? - Over the course of a year, a tractor-trailer commutes 160,000 miles across America.

Lesson 16 Homework
This video demonstrates how to divide with ten-patterns using place value charts, number disks, and decomposition.
- Divide. Draw number disks to show your thinking for (a) and (c). You may draw disks on your personal white board to solve the others if necessary.
a. 300 ÷ 10
b. 450 ÷ 10
d. 730,000 ÷ 100
f. 680,000 ÷ 1,000 - Divide. The first one is done for you.
a. 18,000 ÷ 20
= 18,000 ÷ 10 ÷ 2
= 1,800 ÷ 2
= 900
b. 18,000 ÷ 200
c. 18,000 ÷ 2,000
