DIVISION OF MONEY LESSON
Operations
Teachers 
tell the students: You’ve
already learned 3
mathematical operations with
money.
These are addition,
subtraction and
multiplication. The fourth
operation we’re going to
learn is money division. You know
that subtraction is the
inverse of addition.
(Show an example on the
board now. Ex. 7+3 = 10;
therefore, the inverse is 10
– 3 = 7). The inverse
operation of multiplication
is division. Let’s see how
it works.
Examples of Money Division
Teacher: Here is an
example of when to use
division:
Liz has 15
coins. She wants to divide
them into groups of 5 (each
group will have 5 coins).
How many groups will she
have?
15 (÷) 5 = ?
This is a
division problem, because we
need to divide 15 coins into
groups of 5. To solve it,
ask yourself “How many
groups of 5 are there in
15?” To figure this out,
think of the inverse, or
multiplication problem. Ask
yourself, “What times 5
equals 15?” The answer is
3, since 3 x 5 = 15.
Here is the problem:
15÷ 5 = 3.
Another way to write this
is:
3
5) 15
Division of Money Vocabulary
Quotient: the
answer to a division problem
Dividend: the
number you are dividing
Divisor: the
number you are dividing by
In the following example,
the dividend is 15, the
divisor is 5, and the
quotient is 3.
15(dividend) ÷ 5(divisor) = 3(quotient)
Teachers: try a few
problems with the students
to check understanding.
(12 ÷ 4 = 3) (49 ÷ 7
= 7) (63 ÷ 9 = 7)
(30 ÷ 5 = 6) (16 ÷8 =
2) (30 ÷ 3 = 10)
RULES FOR 0 AND 1
Rules
for 0
1. 0 divided by any number
(except 0) equals 0.
0 ÷ 9 =
0
0 ÷ 3 = 0
2. You cannot divide by 0.
9 ÷ 0 is an impossible
problem
Rules
for 1
1. Any number, except 0,
divided by itself equal 1.
9 ÷ 9 =
1
3 ÷ 3 = 1
2. Any number divided by one
equals itself.
4 ÷ 1 =
4
6 ÷ 1 = 6
