Transcripts
have you ever been overwhelmed by
a multiplication chart i mean 144
numbers a bit overwhelming 12 times 12
oh my goodness well in this video here
today i'm going to share with you
several hacks to make this
multiplication chart
a bit more manageable and actually you
probably know more than you think you do
welcome to purely persistent i'm
michelle
okay so here's just a standard
multiplication chart that i printed
so let's go over this everybody knows
one
times any number right so one times one
is one one times two is two
easy peasy and same going the other way
our tens we've got that ten times one is
ten
ten times two is twenty it's easy
now the elevens are also just as easy
because
one times one is eleven two times
eleven is twenty-two you just double the
number
and on these ones here that get a little
bit harder just use a calculator
all right we've got our fives down 5 10
15
20 25 30 35 40.
[Music]
okay twos times one is two
two times two is four this seems to be
one that if you can count by twos which
i'm sure you can are much
easier and they're always going to be
even numbers right
now if you can do twos then you can do
fours
you just multiply it by two so
two times three is six multiply that by
two
and we get twelve so fours
are pretty much like the twos
now threes here can be a little bit
challenging but if you can count by
threes
3 6 9 12
and you can get a hang of it more like
look at this we have covered so much of
this board
now if you'd like to see more videos
like this definitely give it a big
thumbs up now here's a trick for 12.
let's say i want to go 12 times
5 well i can just basically take
10 times 5 which i know is really easy
50 and then 2 times 5
which is 10. so my answer is 60.
so really with your 12s just take 10
times the number which is easy and 2
times the number which is easy and then
add them up together
but then of course you can always use
your handy calculator
so there goes the twelves
to do the nines i want you to put your
hands just like this
now let's say i need to go nine times
four tuck in your fourth finger
and the answer is forty five
let's try another one nine times seven
put in your seventh finger and we have
six
d3 now notice that all these numbers
added up together
do equal nine but let's try another one
nine times two
we have one and eight so the answer is
eighteen nine times nine tuck in the
ninth finger
we have eighty one
now whoever said we couldn't multiply
using our fingers
there go the nines
nine times eight is really blue because
it's an
old seventy-two now most people tend to
know
what a number squared is or a number
times itself so here
six times six is thirty-six seven times
seven is forty-nine
eight times eight is sixty-four i
dropped eight
and eight on the floor picked it up now
at sixty-four
now we started with this whole thing 144
and look now we only have one
two three four five six
but wait isn't six times seven
forty-two and seven times six
forty-two notice
we can get rid of a couple more because
six times seven is the same thing as
seven times six
eight times seven is eight times six
so really most of these
you understand and you got these
except for these three right here so
we're going to make note cards
[Music]
all right six times
seven flip it over
forty-two
and now i take these note cards and quiz
myself quick six times seven
forty-two six times eight forty-eight
seven times eight
fifty-six i hope that this
multiplication
chart with our couple little note cards
really helps you
and makes you a little bit more
confident in your multiplication
now remember if you have multiplication
down you've got division down too
now if the numbers get too big remember
you have your trusty calculator that is
always there to help you comment below
if you have any
multiplication addition subtraction or
any math hacks
that can help us out thank you for
sticking to the end of the video i hope
that you have a beautiful day
and remember to be purely persistent
okay some of these are going to take a
bit of work you're going to have to use
these little note cards
and practice over and over and over
maybe practice at the grocery store when
you're in line
you know instead of pulling out your
phone and texting maybe
do your little cards first quickly and
then do your texting
