Hopefully we will get to do
some “Hands-On” work. I
love it when I get to use my
hands!
Today we will
learn and be
working on
DIVISION.
Guys come back we are
going to learn something
new today.
Why didn’t you say
that in the
beginning. I love to
soak in new
information.
I’m so Excited!
I can’t wait to
learn more
math.
Let me go round up the gang!

Let’s Check
our
vocabulary
first
Divisor
Quotient
Dividend
Step 1 in Long Division
1. Divide
• Divide 2 into the first
number in the dividend.
• Think how many 2’s will
fit into 7.
• Write that number
directly above the
number you divided into.
How
many 2’s
will go
into 7?

• Multiply the divisor
times the first number
in the quotient.
• Write your answer
directly under the 7
or the number you
just divided.

2x3=6
Step 3 in Long Division
3. Subtract •
Patrick
Draw a line under
the 6.
• Write a
subtraction sign
next to the 6.
• Subtract 6 from 7.
• Write your
answer directly
below the 6.

Step 4 in Long Division
4. Bring
Down
Gary
• Go to the next
number to the
right of the 7.
• Write an arrow
under the 2.
• Bring down the 2
next to the 1.

Step 5 in Long Division
• This is where you
5. Repeat decide whether
you repeat the 5
or
steps of division.
Remainder• If your divisor can
divide into your
new number, 12,
or if you have
numbers that
haven’t been
brought down ,
you repeat the 5

steps of division.

• Multiply your
divisor 2, with
your new number
in the quotient, 6.
• Place your
answer directly
under the 12.

Step 4 in Long Division
4. Bring
Down
• Look at your
dividend to see if
there are any
more numbers to
bring down.
• If not, move to
step 5.

Step 5 in Long Division
5. Repeat •
or
Remainder
Since there are
no more numbers
to bring down & 2
will not divide into
0, you do not
repeat the steps
of division.
• The number left
over, if other than
zero becomes the
remainder.
