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. 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.
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. And if you gave this description to an 8 year-old, you’d probably get a reaction — like this.
To a Math expert, this standard makes sense, but to a kid, it’s absolute torture. I chose this example specifically because fractions are foundational to algebra, trigonometry and even calculus. So if kids don’t understand fractions in elementary and middle school, they’ve got 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?”
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.
