Keywords

💡Multiplication Chart

A multiplication chart, also known as a times table, is a mathematical tool used to help memorize the products of multiplication for numbers typically from 1 to 12. In the video, the multiplication chart is presented as a potentially overwhelming tool but is then broken down into manageable parts using various 'hacks' to make memorization easier. The video aims to demystify the chart by teaching viewers how to calculate products more intuitively.

💡Hacks

In the context of the video, 'hacks' refer to shortcuts or tricks that simplify the process of memorizing or calculating multiplication facts. The presenter shares several hacks, such as doubling a number to find multiples of eleven or using the fingers to calculate products of nine, making the multiplication chart more accessible and less daunting.

💡Counting by Twos

Counting by twos is a method of counting in increments of two, which is used in the video to simplify the memorization of multiplication facts for the number two. By counting in this way, one can easily determine that two times two is four, and then by doubling that result, two times four becomes eight, and so on. This method is used to illustrate how multiplication can be approached in a more intuitive manner.

💡Even Numbers

Even numbers are integers divisible by two, resulting in no remainder. In the video, the concept of even numbers is tied to the multiplication of the number two, where the presenter explains that the products of multiplying any number by two will always be even. This is used to reinforce the pattern and predictability of multiplication results.

💡Counting by Threes

Similar to counting by twos, counting by threes is a method of counting in increments of three. The video uses this technique to help viewers understand the pattern in the multiplication of the number three, such as three times one being three, three times two being six, and so on, up to three times twelve being thirty-six.

💡Note Cards

Note cards are small pieces of card or paper used for memorization purposes. In the video, the presenter suggests using note cards to write down difficult multiplication facts, such as six times seven equals forty-two, to help with memorization. The note cards are then used for self-quizzing, which is a practical application of the memorization technique discussed.

💡Practice

Practice, as mentioned in the video, is the act of repeatedly performing an activity to improve at it. The presenter encourages viewers to practice their multiplication skills using the note cards and the various hacks shared throughout the video. Practice is emphasized as a key component in mastering the multiplication chart.

💡Calculator

A calculator is an electronic device used to perform calculations. In the video, the presenter mentions using a calculator as a backup tool when the multiplication facts become too complex or when one needs a quick check for accuracy. This highlights the balance between learning mathematical skills and utilizing technology for assistance.

💡Division

Division is the mathematical operation of splitting a number into a number of equal parts. The video connects multiplication and division by stating that mastering multiplication inherently helps with division, as they are inverse operations. For example, if one knows that six times seven is forty-two, they can also deduce that forty-two divided by six is seven.

💡Persistence

Persistence is the quality of continuing despite difficulties. The video's title, 'Purely Persistent,' and the presenter's encouragement to 'be purely persistent' emphasize the importance of maintaining effort and not giving up when faced with challenges, such as mastering the multiplication chart.

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
