Application Problem

The area of a vegetable garden is 200 ft^{2}. 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 m
^{2}. The length is 90 m.

a. What is the width of the banquet hall?

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
