Reviewer: Ariana Bleau Lugo 26% on the nation’s report card, that’s the percentage

of U.S. 12th graders who are proficient in Math. In America, we pride ourselves

as being an exceptional country. But does 26% sound exceptional to you? Raise your hand if you think as a country

we need to do way better than this. I’m with you. We all need Math, but why

are so many kids confused by it? Is it because only 26% of people

are hardwired for Math, while 74% are not? After working with thousands of kids,

I can tell you, this isn’t the case at all. Kids don’t understand Math because we’ve been teaching it

as a dehumanized subject. But if we make Math human again,

it will start to make sense again. You’re probably wondering: “How was Math ever human

in the first place?” So, think about it. (Laughter) Math is a human language,

just like English, Spanish or Chinese, because it allows people

to communicate with each other. Even in ancient times,

people needed the language of Math to conduct trade, to build monuments, and to measure the land for farming. This idea of Math as a language

isn’t exactly new. A great philosopher once said: “The laws of nature are written

in the language of mathematics.” So you see?

Even Galileo agrees with me. (Laughter) But somewhere along the line, we’ve taken this language of math, which is about the real world around us, and we’ve abstracted it

beyond recognition. And that’s why kids are confused. Let me show you what I mean. Read this 3rd grade

California Math Standard and see if it would make sense

to an eight year-old. “Understand a fraction 1/b

as the quantity formed by 1 part when a whole is partitioned

into b equal parts.” Understand the fraction a/b as the quantity formed

by a parts of size 1/b. (Laughter) And if you gave this description

to an 8 year-old, you’d probably get a reaction…

like this. (Laughter) To a Math expert,

this standard makes sense, But to a kid, it’s absolute torture. I chose this example

specifically because fractions are fundational to algebra,

trigonometry and even calculus. So if kids don’t understand fractions

in elementary and middle school, they have a tough road

ahead of them in high-school But is there a way to make fractions

simple and easy for kids to understand? Yes! Just remember that Math is a language

and use that to your advantage. For example, when I teach 5th graders

how to add and subtract fractions, I start with the apples + apples lesson. First I ask,

“What’s 1 apple plus 1 apple?” And kids will often say 2,

which is partially correct. Have them include the words as well

since math is a language. So it’s not just 2, it’s 2 apples. Next is 3 pencils plus 2 pencils. You all know that pencils + pencils

give you pencils, so everyone, how many pencils? Audience: 5 pencils. 5 pencils is right. And the key is you included the words. I tried this lesson

with my 5-year-old niece once. After she added pencils and pencils,

I asked her, “What’s 4 billion plus 1 billion?” And my aunt overheard this

and she scolded me and said, “Are you crazy? She’s in kindergarten! How’s she supposed to know

4 billion plus 1 billion?!” (Laughter) Undaunted, my niece finishes counting,

looks up and says: “5 billion?” And I said:

“That is right, it is 5 billion.” My aunt just shook her head and laughed because she did not expect that

from a 5-year-old. But all you have to do

is take a language approach and Math becomes intuitive

and easy to understand. Then I asked her a question that kindergartners

are definitely not supposed to know: “What’s one third plus one third?” And immediately she answered:

“2 thirds”. So if you’re wondering

how could she possibly know that when she doesn’t know about

numerators and denominators yet? You see, she wasn’t thinking

about numerators and denominators. She thought of the problem this way. And she used 1 apple + 1 apple

as her analogy to understand 1 third plus 1 third. So if even a kidergartner

can add fractions, you better believe that

every 5th grader can do it as well. (Applause) Just for fun, I asked her

a high-school algebra question: What’s 7 x² plus 2 x²? And this little 5-year-old girl

correctly answered, 9 x². And she didn’t need any exponent rules

to figure that out. So when people say that we are

either hardwired for math or not, it’s not true. Math is a human language, so we all have the ability

to understand it. (Laughter) We need to take a language

approach to math urgently because too many kids are lost

and are anxious about math and it doesn’t have to be that way! I worked with an angry,

frustrated high-school student once who couldn’t pass algebra because she only knew 44%

of her multiplication facts. I told her, “That’s like trying to read

and only knowing 44% of the alphabet. It’s holding you back.” She couldn’t factor or solve equations

and she had no confidence in Math. As a result, this teenager

had no confidence in herself. I told her,

“We have to start with multiplication because once you know all your facts

by heart, everything gets easier, and it’ll be like having a fast pass

to every ride of Disneyland.” (Laughter) What do you think?” And she said “Ok.” So she systematically learned

her times tables in 4 weeks and yes, even multiplication

has language embedded in it. You’d be surprised how many kids

don’t realize 7 times 3 can be spelled out as “seven times” 3, which just means 3 seven times,

just like this. So when kids see it this way, they quickly realize

that repeated addition is slow and inconvenient, so they gladly memorize

that 3 seven times always gives you 21. So for this teenager

who was at risk of dropping out, becoming fluent

and confident in multiplication was a game changer. Because for the first time

she could focus on problem solving instead of counting on her fingers. I knew she had turned the corner when she figured out

that a 2-year car lease at $445 a month

would cost you $10,680 and she looked at me disapprovingly

and said: “Mr Polisoc, that’s expensive!” (Laughter) At that moment, math was no longer

causing problems for her, but she was using math to solve problems

as a responsible adult would. As an educator, it’s my duty

to challenge kids to reach higher, so I leave you with this challenge. Our country is stuck at 26% proficiency, and I challenge you

to push that number higher. This is important because mathematical

thinking not only builds young minds, but our kids need it to imagine

and build a future that doesn’t yet exist. Meeting this challenge can be

as simple as apples + apples. Insist that we teach Math

as a human language and we will get there sooner,

rather than later. Thank you! (Applause)

Not hoarding away profit in offshore banks isn't hard either. This guy hates women and children.

Arrest this man, he talks in maths.

Is this why we have an oligarchy and we do not have democracy ?

Ask 5 year old , one third +one fifth

I thought it is philosophic talk but it is a bad talking it so minute👎

This guy – genius! Love it!

Nah, you are either born with high IQ or average IQ. There is so much we have yet to discover about our own brains.

Ok now show us some calculus

This is a roundabout way of saying math is hard because of these gatekeepers we have for professors and/teachers

Can he be my math teacher

We all know the homework and tests are not this easy

Yes and now explain scalar product and functions

what if you have dyscalculia…

Watch at 2x no need to thank me.

Not only kids it's with adults as well 😒

I love mathematics.

And I have a professional teacher…

pro tip: if you think that you have understood sth about maths well call a friend of yours and explain it to them. If they understand it you are good. If they can explain it you are better. Then call your little brother/sister and explain it. If they understand it you are the best. If they can explain it, you are probably Einstein.

-my math teacher at high school

I like this, this is cool… now imagine him teaching this wearing a goat mask! I mean then we'd be in business amirite!

Wish he was my teacher

Hence,Asians are smarter is proved.

Now I can solve maths by listening to BTS music

i dare you to do the same with complex numbers

Math is awful. I'm about to go into the 11th grade and I can really only add subtract and barely multiply. I actually had to completely re-learn addition. I have had six professional tutors, before school and after school sessions, summer programs, at home teaching and peer tutoring. I, in the most literal sense, have learned absolutely nothing. I fill entire notebooks with notes, use Khan Academy, use text books, use math related apps and still after 16 years of living I have made lower than the least bit of headway in learning this subject. This subject has made me seriously suicidal and it's just unbearable and seemingly impossible to do things in this subject that most individuals find extraordinarily easy as if it were second nature.

Its a hard language !

One of the guy from India who cleared Indian math iitjee exam is now the CEO of Google😂After watching this video I just got a renewed sense of hope

Sign me up for this teacher

carl munch the pyramid code now that's math

Got it!!!. Now try telling her to explain her answers….gotch ya

Well go then and do speak it, just dont bloody bother others.

I have a lot of problems trying to find equations to draw paths of shortest distances on non-flat grids. Trust me, I'm not the only one. It's tough stuff.

gayiiiii

This is just calculations,math is tough.

a teachers perspective can either make you fall in love with the subject or youll hate it till your last breath

How I wish I watched TEDx 10 years ago

Here in Chiapas, I use the method that he describes at 3:19 .

wowwwwwwww dant u vearry mucccch

Watching this video as I’m struggling with Linear Algebra/:

I need the motivation to keep on going!!!!

I wish i could go back in time and kill whoever created math…

And i hate problem solving

Well if you don't want to learn math then don't learn math. If you want to learn math then you can just major in it. I think for those people who don't like math, math is a really horrible subject to study. But if you really enjoy math it is an amazing subject, but you have to learn how to deal with the struggle not just blame your teachers for not being able to teach

This is old hat…common core is what screwed so many kids. Back to basics is what I say.

Nope. I'm actually GOOD at languages. I'm fluent in three. But I can't do even basic math. If it was a language, I would have managed somehow. I'd excel at the most difficult language before I'd be able to do even high school math.

who even listens to ted talks

rubbish, Coming from a man confident with maths.

so fractions are easy..wtf

If these type math is a language then slangs is also our "bhaiyya type of guys" language

It's fine. I will get minions to do my math.

I can give math tricks if u want

Paz na terra e pau no seu cu

فديو رائع وجميل.

Next we tell the fifth graders: "count how many brain cells I lost whilst watching this video."

So sqrt2+sqrt2 = sqrt4….? Tf

the biggest issue isnt the subject itself, its how its taught in the US and similar countries. they dont teach the concepts, they teach the material on the standardized tests.

Wow!

is math really a language, or is it just a concept?

This is why we made a calculus youtube channel.

Omg, someone payed to watch this live?

M-mental

A-Abuse

T- To

H-Human

;-;

Your lecture does have power in it.

Mathematics!

I love math

it helps me. thank you so much.

But fraction is learned in Grade Two in primary school in China.And they will learn more difficult than aboard,such as America,England and so on.I support your idea but is not suitting everyone

Nail, head, hit!

This man is my teacher

agreed to this speech life is hard without math life is also hard if the math before and now its little more hard than it was before.. and if u do agree not every one is gifted in math.. we all cant denied the truth because it is the truth i struggel in math since i was in 5 and 6 grade and in high school our math is a murder and hard to understand im willing to learn math but its really hard.. so agree with me or not u all khow what i mean

Suuuper😍😎😀😋❤👌👍

That is why I'm not good at math because I have trouble learning new languages

The old timers who knew numbers that I remember

OMG! I’M HONESTLY LEARNING WHATDAHEK

Thank you.

You just made it more harder for me by saying math is a language…

Mostly we use common sense

After showing my five year old niece the apple plus apple lesson , I asked her what is pie and she happily answered “pie is 3.14159265358979323846264338327950284197169399375105820974944592307816428620899862803482534211706798214808651328230664709384460955058223172535908128481117450284102701938521105559644622948954930381964428810975665933446128475648233786783165271201909145648566923460348610454326648213393607260249141273724587006606315588174881520920962829254091715364367892590360011330530548820466521384146951941511694330572703657595919530921861173819361179310511854807446237996274956735188575272489122793818301194912983367336244065664308602139494639522473719070217986094370277053921717629317675238467481846766940513200056812714526356082778577134275778960917363717872

It’s a language that’s hard to learn…

They say Math was easy but then when the letters came in it made it complicated…

its hard to reconcile numbers and letters.

I want to learn math, but my math teacher just isn't a normal person. I can't take her.

But isn’t learning a new language hard?

Well I guess I’m bad at learning languages then..

Beautiful put together

HDR palisoc is my favorite teacher he’s in my shcool

Studying for the Asvab and the math portion is giving me headaches. I just wanna hunt drug dealers and be a badass

I want this guy to be my maths teacher.

Hm, isn't that how we teach math already? That is how I learned it and that is how I teach it :P.

I’m gonna fail my math test.

I’m sorry but is no one pointing out that this guy is Asian…

Math anxiety is a world wide problem.

Well, that's weird, i know how to speak 3 languages, but can't understand maths at all…

Yea maths isn't hard

The math language is …

Tell that to someone taking their first university proofs class

“In America we pride ourselves on being an exceptional country”

Yea, your the only ones in the world that feel that way

I'm in academic math my teacher writes a note down thinks we understand it but for me I need like in depth explaining not just a note

best math ted talk

Is a language really easy? If math is not hard, can he prove Riemann hypothesis?

I would have been so mad if my teachers made me do this

Can someone get this guy a glass of water.

But the question is how can i find and use that intuition ?

Why do all good maths profs here in youtube 🙁
