1. Divide. Draw place value 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
300 : 10 = 30
100                 10
100 -à :10  10
10                   10
10 + 10 + 10 = 30

b. 450 : 10
450 : 10 = 45

c. 18,000 : 100
18,000 : 100 = 180
10,000                           100
1,000                             10
1,000                             10
1,000                             10
1,000 –à : 100 =     10
1,000                             10
1,000                             10
1,000                             10
1,000                             10
100 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 = 180

d. 730,000 : 100
730,000 : 100 = 7300

e. 900,000 : 1,000
900,000 : 1,000 = 900

f. 680,000 : 1,000
68,000 : 1,000 = 680

1. Divide. The first one is done for you.

a. 18,000 : 20
18,000 : 20 = 18,000 : 10 : 2 = 1,800 + 2 = 900

b. 18,000 : 200
18,000 : 200 = 18,000 : 100 : 2 = 180 : 2 = 90

c. 18,000 : 2,000
18,000 : 2,000 = 18,000 : 1,000 : 2 = 18 : 2 = 9

d. 420,000 : 60
420,000 : 60 = 420,000 : 2 : 6 = 42,000 : 6 = 7,000

e. 420,000 : 600
420,000 : 600 = 420,000 : 100 : 6 = 4,200 : 6 = 700

f. 420,000 : 6,000
420,000 : 6,000 = 420,000 : 11,000 : 6 = 420 : 6 = 70

g. 24,000 : 30
24,000 : 30 = 24,000 : 10 : 3 = 2,400 : 3 = 800

h. 560,000 : 700
560,000 : 700 = 560,000 : 100 : 7 = 5,600 : 7 = 800

i. 450,000 : 9,000
450,000 : 9,000 = 450,000 : 1,000 : 9 = 450 : 9 = 50

1. A stadium holds 50,000 people. The stadium is divided into 250 different setting sections. How many seats are in each section?

50,000 : 250 = 50,000 : 10 : 25 = 5,000 : 25 = 200
There are a total of 200 seats in each section.

1. Over the course of a year, a tractor trailer commutes 160,000 miles across America.

a. Assuming a trucker changes his tires every 40,000 miles, and that he starts with a brand new set of tires, how many sets of tires will he use in a year?
160,000/40,000 = 16,000 : 10,000 : 4 = 16 : 4 = 4
He will use 4 sets of tires in a year.

b. If the trucker changes the oil every 10,000 miles, and he starts the year with a fresh oil change, how many times will he change the oil in a year?
160,000/10,000 = 16
He will change the oil 16 times in a year.
