Let’s Learn Our Times Tables!
Why is this Important?
We use multiplication in our every day
lives. You will begin to learn it here today
and will never forget it. There will be a quiz
to test your skills at the end so be sure to
pay close attention and do your best to
learn how to multiply!

What is Multiplication?
Multiplication is the process of computing
the sum of a number with itself a specified
number of times. In more simple terms if
the problem is 4 x 6 it is asking what is 6 +
6 + 6 + 6 or 4 + 4 + 4 + 4 + 4 + 4. Meaning
what is the total of adding 4 together 6
times or adding 6 together 4 times.

QUIZ!
Choos
e one!
Zeros
Zero is easy… when multiplying by a zero
the answer is always zero!
Examples:
Simple!
0x8=0
12 x 0 = 0
Back
Ones
Next to zero’s, one’s are the next easiest.
Any number that is multiplied by one, is
the number itself!
Examples:
9x1=9
1x3=3

Twos
If you know how to add, two’s will not be a
problem for you at all! You simply take the
number that you are multiplying by and
double it. (Answer is always even)
Example:
Like this: 5 x 2 = ?
11 x 2 = 22
5 + 5 = 10
Back
Therefore, the answer to 5 x 2 is 10!
Threes
It begins to get a little harder now. Three’s
are like two’s except instead of doubling
the number, you triple it. Continue to think
addition! On the next page there is a hint.
Examples:
3 x 7 = 7 + 7 + 7 = 21
8 x 3 = 8 + 8 + 8 = 24
You’re
doing
great!
Hint for Threes
Anytime you multiply by 3, the digits of the
answer add up to 3, 6, or 9! It is a great
way to check your work. Lets try it out.
4 x 3 = 12
8 x 3 = 24
3 x 6 = 18
1+2=3
2+4=6
1+8=9
Always
check
your
work
Back
Fours
When you have to multiply a number by
four think “double double”. Just like for
two’s you double the number and then you
just double it again to get the answer!
(Answer is always even)
Examples:
4 x 7 = 7 + 7 = 14 and 14 + 14 = 28
12 x 4 = 12 + 12 = 24 and 24 + 24 = 48
Back
Fives
Five’s are fun and easy! When you multiply
an even number by a five the number in
the ones place (20) is always a zero.
When you multiply by an odd number, the
number in the ones place is always a 5.
(35) To find the number in the tens place
(20) or (35) it depends on what the
number you are multiplying is. Continue on
next page.
Fives
When the number is even, for example 6,
and you multiply by 5, the answer in the
tens is just half of the even number (6) and
then 0. So 5 x 6 would be 30. The 3 is half
of 6 and it is zero because the number is
even.
5, 10, 15,
20, 25,
Examples:
30..
5 x 4 = 20
10 x 5 = 50
8 x 5 = 40
5 x 12 = 60
Fives
When the number that you are multiplying by
is odd. You do the same thing except first you
subtract 1 to find the number in the tens
place. So if you are multiplying by 7 you
minus one to get 6, take half (3) and add a 5
to the ones place because it is odd.
Examples:
9 x 5 = 45 (9-1 is 8 and 4 is half of 8)
Back
5 x 3 = 15 (3-1 is 2 and 1 is half of 2)
Sixes
Sixes are tough because there is not a
great way to learn them! In order to
remember some of them you must
memorize them or think about addition in
your head. You know how to do 0-5. You
will know 9-12 but for now we will focus on
6, 7, and 8. 6 and 8 have a rhyming tone,
You’re
7 is the toughest.
over half
way!
Sixes
You can
do it!
Rhyming: 6 times 6 is 36
6 times 8 is 48
Memorize: 6 x 7 = 42
If you can remember the rhymes you will
be able to remember that 6 times 7 is 42
because of the multiplication rule you
know that if 6 times 6 is 36 and you just
want to add one more six then you add 6
to 36 to get 42.

Let’s Review!
We know any number times 0 is 0.
We know any number times 1 is the number.
For 2’s we just double the number.
For 3’s we triple the number and check that the
answer adds up to 3, 6, or 9.
We know for 4’s we think “double double”.
For 5’s we look at what is even and odd and
dividing numbers in half. (always end in 0 or 5)
Back
6’s are rhyming and memorization.
5’s and
2’s
Sevens
Seven’s are tricky. Remember the five’s?
When multiplying by 7 multiply the number
by 5 first. Then double the number you are
multiplying by. Add the two numbers
together to get the answer.
Examples:
7 x 6 = (6 x 5) + (6 x 2) = 30 + 12 = 42
Back
4 x 7 = (4 x 5) + (4 x 2) = 20 + 8 = 28
Eights
Not a lot of hints to multiply by 8. But, if you
know all of the other numbers up until this
point you will know how. We have to
memorize 8 x 8 = 64. (hint: he ate and he
ate until he got sick on the floor)
Examples:
8 x 7 = 56
Back
4 x 8 = 32
This is
cool!
Nines
There is a fun trick to multiply by 9. Hold
your hands up with all 10 fingers up.
If
you are multiplying by 7 for example, put
your seventh finger down (from left to
right). The answer to 9 x 7 is left on your
fingers! It is 63. Six fingers on the left and
three on the right.
Nines
On the next few slides you will learn how to
multiply 9 by 10, 11, and 12. Look at the
examples to review how to multiply by 0-9.
Examples:
3 x 9 = 27 9 x 9 = 81
9 x 8 = 72 5 x 9 = 45
Back
Tens
Back to the easy stuff! When you multiply
by ten all you have to do is add a 0 to the
number you are multiplying by!
Examples:
Whew!
9 x 10 = 90 10 x 10 = 100
10 x 3 = 30
1 x 10 = 10
Back
Elevens
Eleven’s are also simple! When you multiply a
number by 11 you just duplicate the number!
If you are multiplying by 5 for example the
answer is 55. Or you times it by 10, and then
just add the number you are multiplying by.
Examples:
3 x 11 = 33 12 x 11 =
Back
11 x 9 = 99 (12 x 10) + 12 = 132
You
did it!
Twelves
To multiply by twelve’s all you have to do is
multiply the number by 10 first and double
the number you multiplied by and then add
it!
Here are the steps for 12 x 6:
(6 x 10) + (6 x 2) = 60 + 12 = 72
Examples:
Back
3 x 12 = 36 12 x 9 = 108
Last Review!
For seven’s remember we multiply by 5
first, then double the number we are
multiplying by and add them together.
For eight’s we have to remember he ate
and he ate until he got sick on the floor (8
x 8 = 64)
We know that nine’s are fun! We use our
fingers to answer problems with 9.
Tens are the easiest. We just add zero!
Last Review!
 We know that for eleven’s we simply
duplicate the number or we times by 10
and add the number we are multiplying by.
Lastly, for twelve’s we multiply by 10,
double the number we multiplied by and
then just add them together!
