Q & A
What is the current proficiency rate of U.S. 12th graders in Math according to the nation's report card?
-The proficiency rate of U.S. 12th graders in Math is 26%, as mentioned in the script.
What does the speaker believe is the reason behind the low proficiency rate in Math among students?
-The speaker believes that students struggle with Math because it has been taught as a dehumanized subject, rather than as a human language that makes sense in the context of the real world.
Why does the speaker compare Math to languages like English, Spanish, or Chinese?
-The speaker compares Math to these languages because, like them, Math is a means of communication that has been essential for trade, building, and land measurement since ancient times.
What philosopher is quoted in the script, and what did they say about the relationship between the laws of nature and mathematics?
-The philosopher Galileo is quoted, saying, 'The laws of nature are written in the language of mathematics,' implying that Math is intrinsic to understanding the world around us.
Why do students find fractions confusing according to the script?
-Students find fractions confusing because the way they are taught has become abstract and disconnected from the real-world context, making it difficult for students to relate to and understand.
What is the 'apples + apples' lesson mentioned in the script, and how does it help students understand fractions?
-The 'apples + apples' lesson is a teaching method where the teacher starts with simple, relatable objects like apples to illustrate the concept of adding fractions. It helps students understand that adding like items (apples in this case) results in a sum that still represents the same kind of item, thus making the concept of adding fractions more intuitive.
How did the speaker's 5-year-old niece demonstrate understanding of adding fractions without knowing about numerators and denominators?
-The niece demonstrated understanding by using the analogy of adding apples to comprehend the addition of one third plus one third, which she correctly answered as '2 thirds,' showing that she grasped the concept without needing to know the formal mathematical terms.
What high-school algebra question did the speaker's 5-year-old niece answer correctly, and what does this suggest about the potential for all students to understand Math?
-The niece correctly answered the question 'What's 7 x² plus 2 x²?' with '9 x².' This suggests that all students have the potential to understand Math if it is taught in a way that is intuitive and relatable to them.
Why did the high-school student the speaker worked with struggle with algebra, and how was this issue resolved?
-The high-school student struggled with algebra because she only knew 44% of her multiplication facts, which is like trying to read without knowing most of the alphabet. The issue was resolved by systematically learning her times tables, which improved her overall fluency and confidence in Math.
What challenge does the speaker issue to the audience, and why is it important for the future?
-The speaker challenges the audience to push the Math proficiency rate higher than the current 26%. It is important because mathematical thinking is crucial for young minds to imagine and build a future that doesn't yet exist, and teaching Math as a human language can help achieve this goal.

Transcripts
Transcriber: Radu Chirila 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)
