Here are some more people responding to Andrew Hacker’s article.
I’ve included a link and my favorite quote.
Rob Knop at Galactic Interactions.
Liberal arts education is to make people into good citizens, not into good workers. They are to acquaint you with the intellectual achievements of humankind. That is why we read the Iliad, why we watch a performance of Hamlet, why we learn about the history of ancient Greece, and, yes, why we study algebra.
PZ Myers at Pharyngula.
We live in a technological society. Not learning algebra in the public school system means those kids will not be prepared, will not be qualified, to do anything in science and engineering. I’m serious: if you don’t know algebra, you can’t do basic quantitative chemistry, and if you can’t do that, you can’t do biology. At all. Not the molecular/biochemical/bench side, not the ecological/evolutionary/field side. You can’t do physics, that’s for sure. Forget math and statistics. If you’re not capable of grasping statistics, forget psychology, too.
Dave Schuler at the Glittering Eye.
I’ll go farther and hazard a guess that poli sci, like the other social sciences, is much more empirical and quantitative now than it was then and that Dr. Hacker would be hard put to earn a doctorate in his own field nowadays.
Economists have shown that cognitive skills–especially math and science–are robust predictors of individual income, of a country’s economic growth, and of the distribution of income within a country (e.g. Hanushek & Kimko, 2000; Hanushek & Woessmann, 2008).

We need more problem solvers and they need algebra.
A patient who understands graphs and inequalities will have a much better control of their health than someone who has trouble with even basic arithmetic. This is not a case of mathematics being a prerequisite for a job, the usual argument for numeracy. This is mathematics making a difference in your own health.
My favorite response is from Alexandra Petri at The Washington Post.
When my friends call me late at night complaining about how hard it is to eliminate exes from the equation, we never turn out to be talking about the same thing.

On that note, here’s commenter Ben: Is English literature necessary? I never ran into Moby Dick during my career. Is Gym class necessary? I never had to do a pull up. Is Physics necessary? When was I called upon to do vector analysis? Is Biology necessary? I think only French Chefs have to dissect frogs in their careers. It must be tough to teach. What’s the point. Walmart has all the stuff we’ll ever need. Supersize that happy meal. We’re just turning into a bunch of consumers anyway, lets just stop pretending that we need to know anything.
Evelyn Lamb at Scientific American.
Few pre-college math teachers majored or even minored in math, and until more teachers do, improvements will be hard to come by. Ironically, it seems that people who have mastered “useless” algebra and other higher math topics tend to get jobs that pay more than middle school math teachers earn. I have the utmost respect for people with math degrees who choose to teach in spite of the poor pay and discipline problems, but few people make that choice. Math education needs help, but Hacker’s suggestions throw out the baby with the bathwater.
RiShawn Biddle at Dropout Nation
The advent of the Internet and the emergence of quantifiable data is making math skills critical to many white-collar professions; marketers and public relations staffers, for example, have to understand the arcane aspects of statistics in order to analyze data on ad campaigns, while reporters and editorialists need stronger math skills as well.
Rollin Bishop at Geekosystem
To say that we are failing and need to do something about it is absolutely correct. To say we need to remove it from our path as a hindrance rather than overcoming it with improved teaching methods, enhanced mathematics programs, and funding in general is a mistake.
My own humble contribution.
If you don’t know a subject, how do you know if you couldn’t use it?
Here are some more. A recurring theme is that Algebra should be required but we should probably rethink how we teach it.
Dan Meyer at dy/dan:
The more interesting question is, “How should we define Algebra in 2012 and how should we teach it?” Those questions don’t even seem to be on Hacker’s radar.
When students say they have difficultly with algebra, that’s usually not the entire story. Typically, that means they have also trouble with arithmetic. There’s a reason why the ability to do long division is correlated with long-term mathematics performance: you have to master the basics.
Ilana Horn at teaching/math/culture
Hacker is correct that we are not teaching enough children meaningful mathematics in schools. The problem, however, is not Algebra. The problem is Algebra as Usual.
My girlfriend is a fine artist, with an MFA in sculpting from a school . . . in New York City. Earlier this year, she was the recipient of a month-long artist residency in Taiwan where she put together an outdoor installation in knitted recycled plastic as part of an exhibit on environmental themes. She has a fairly high proficiency at math . . . and this gets used routinely in her career. She has to estimate volumes of complicated shapes she’s planning to put together, so as to procure materials . . . She has to do calculations with money so as to set budgets . . . She has to estimate time for projects that might last many months. At some point she generated a calculation for people, time, and material to cover the Eiffel Tower in tiny crocheted plastic leaves (a long-term goal).

Why learn math?
When are we ever going to use this? I’m sure other teachers hear this but it seems to be especially prevalent in math classes.
This question is frustrating for two reasons. 1) There is an implied “if you can’t answer then I don’t have to learn it.” 2) I could come up with an infinite number of answers and they, probably, would not be adequate. Students invariably say yeah yeah, but I don’t planning on doing that.
But it is a fair question. I’ve created this blog, in part, to hone my answers. Here are my current top ten reasons. (They are not in any particular order except, perhaps, #1 and 10.)
Learning math can help you….
10. Prepare for a career.
In my humble opinion, this is the least important reason to learn math….
9. Develop problem solving skills.
You can only develop problem solving skills by …wait for it… solving problems. I don’t mean problems where the teacher shows you an example and you do 20 problems just like it. I am referring to problems you’ve never seen before. Math gives you practice in organizing what you know, rearranging information, testing hypotheses, etc. These are the same skills you can use in everyday life. Unfortunately, most teachers (including myself… There’s that stupid test each year) take the problem solving element out of math class.
8. Increase your capacity to think analytically
Without props, without manipulatives…. Just with your brain…
7. Be able to learn science
6. Argue better
5. Be less gullible
Astrology is completely bogus. This can be demonstrated. If you don’t understand or believe the reasons (or can’t sit through an explanation), you’re missing some of the skills mentioned above and your math teachers should be fired, (except for the fact that learning is, ultimately, the students’ responsibility.)
4. Distinguish us from animals
What makes humans different? Build tools? Nope, certain apes do it, even ants. Develop language? Nope, dolphins, birds, and primates beat us to it. Use money? Nope. One reason is our ability to think and communicate abstract ideas. One language for doing so is mathematics. (To be fair there are many others: art, music, literature, etc.)
3. Better appreciate the history of our civilization
The industrial revolution was made possible because of thermodynamics which require an understanding of differential equations which is the main sequel to Newton’s calculus. The exploration of the world happened because the Egyptians knew the earth was round. etc.
2. So you don’t look like an idiot
And to show off at parties…
1. If you understand math…. And can read, you can teach yourself anything….
So when I ask you, “why is math important.” if you say, “to count my money.” I will start banging my head against the wall.
The problem with problem solving….
Math teachers throughout time have said, “math is important to help you develop problem solving skills.” And then they show you how to solve the problem and you know how to solve THAT problem. When faced with a new problem you’re just as lost.
But that’s not the problem.
So we develop quasi real world problems that look open-ended… But, in reality, we expect a certain outcome from the students. We expect them to choose a certain strategy and come up with a particular answer, or range of possible answers. If they don’t, we help them by giving them a strategy.
That’s still not the problem.
The problem is the standards. We look at a content standard and say let’s create a problem that utilizes that standard. We give it to the student and they solve it a different way. And we adjust and give the next students steps to solving the problem. Now we’re back to helping the students more than we should because we’re overly attached to the standards.
I may be exaggerating but… “real world” problem solving is not compatible with content based standards such as California’s.
Developing problem solving skills should be the goal, not understanding the difference between equations of ellipses and hyperbolas.
I hope the Common Core standards are better.
