Why We Should Worry Less About the Achievement Gap

Leadership, Learning, Mission-Driven Work, PreK-12

Math education is a polarizing topic. When people remember their own experience in the math classroom, they typically remember feelings of love or hate… usually the later. But as math education becomes increasingly personalized and experience based, we have an opportunity to shift the connotation that the subject holds.

In his post, Brandon Smith, Senior Mathematician at The MIND Research Institute, a Getting Smart Advocacy Partner describes the power of play in mathematics and how we can transition from a focus on the achievement gap to the “experience gap,” ensuring that ALL students have the opportunity to truly experience math and fall in love with it’s complexity and beauty.

It’s very common to talk about raising student achievement. After all, this is where we see gaps. Doing poorly on an assignment or failing a test denotes “poor achievement” and stands out to teachers, parents and society. We naturally want to fix student achievement. But here’s the twist: The achievement gap is not the root problem, and we hurt our students and ourselves by focusing on it.


More than half of all fourth graders are not proficient in math, and the disparity among groups is alarming — 54% of white students and 64% of Asian/Pacific Islanders are proficient in math, compared to 18% of blacks and 26% of Hispanics, according to the Nation’s Report Card. The gap widens as students progress through school.

The achievement gap is just a symptom of a bigger problem… a dissonance between the rich mathematical experiences students should have and what they actually have. This is what I’ve started calling the “experience gap.” For example, when we teach children division with fractions, we have them memorize “Ours not to reason why … just invert and multiply!” We don’t ask kids to understand the why and how this works — we discourage them from even thinking about it.

Our intentions are good, but we’re focusing on the wrong thing, and it’s hurting students. If students can flip and multiply, they can pass the test — the standard sign of academic achievement. Our worry over the achievement gap puts students into narrow contexts of thought full of vast, isolated content and speedy tricks. Unlike the cereal, tricks aren’t for kids.

What keeps me so excited about my role at MIND Research Institute is that we carve out a path if there isn’t one already in place. We are doing exactly this with the experience gap. Great experiences have tricky problems, twists we didn’t see coming, and structure that we can find if we look. Great experiences put faith in mathematics and in people. A great experience is a chance to play with mathematics — with authentic mathematics where learning happens. We need to give students rich opportunities to learn by doing rather than static observation or rote memorization of rules.


A fourth grader uses highschool level math concepts as she “plays math” at a MIND Research Institute Family Math Night.

Play with math? Why not?

We play basketball, we play football, we play checkers. We even play mathematics-like strategy games such as chess. But we never “play math.”

The achievement gap is primarily concerned with doing math. The experience gap is interested in playing math. Like any sport, to play it you must learn about it and practice. You must persist and overcome adversity. You must operate within its rules. Playing math is no different. A legitimate mathematical experience is rich, deep and challenging — that’s what makes it so engaging.

A simple example. I recently helped organize a Family Math Night at a local school where we spent an evening playing with dice and letting students freely engage with a variety of math concepts. One fourth grader rolled four die and wondered how many four-digit numbers she could make out of the numbers she had rolled. She started writing 3,456; 3,546; 6,543 and so on. She worked and talked through the problem for more than 20 minutes, ultimately solving a high school-level combinatorics concept about permutations. She would never have done this if we were only focused on achievement gaps — this concept isn’t even tested in her grade. But the experience in problem solving, perseverance and self-confidence she gained that night was invaluable. She did this because she was interested in the question, not because we had to raise her test scores.

Never underestimate the power of an interesting question.

We need to revolutionize math perceptions if we want to close the experience gap and eliminate its most evident symptom: the achievement gap. The good news is that we can make such experiences available to people of all levels, not just the already high-achievers. At MIND Research Institute, we are doing exactly this with our national movement, MathMINDs. As we focus on great experiences that keep their mathematical integrity, people can and will rise above their “expected” achievement level and surprise us.

MathMINDs creates environments through math fairs, math camps, math nights and more, where students and families discover they are capable problem-solvers in a mathematical world. One great example open to all students is our national K-12 Game-a-thon. In the Game-a-thon, the students are the ones designing the experiences they want to play. You would be surprised at how creative and persistent students can be when given an opportunity to play with and think about math.

One of last year’s Game-a-thon challengers, Jemma, offered this advice to this year’s participants, “Try to add a different perspective to your game so it will intrigue others. Be ambitious, confident and try to do what no one else will do.” She just might be a future MIND employee.

Let’s start playing.

I agree with most of this except where you blamed the plug-and-chug method on standardized tests. Schools have been teaching plug-and-chug since they started allowing calculators in elementary and middle school classrooms. I graduated high school a long time ago (I had to look up logarithms in a huge book and use graph paper) and went back to college about 7 years ago. One of my college PROFESSORS got very upset with me because I actually worked the math through on Chemistry tests and labs instead of using the method of putting everything in “H”s (that’s what the lines I was supposed to use looked like). I would get the right answer but she couldn’t understand how I got the answer because she only learned plug-and-chug and she was a PROFESSOR. I understood her H-thing and ended up using it to make her happy but she didn’t know how to think through the math and neither did most of the class who also used the H-thing.

Exactly. 100% exactly. Stop trying to teach “facts in a vacuum”where a student may know something for a few minutes, or even remember it for a while, but never actually understand how and when it can be applied, or how it applies to corollary concepts, etc.

Actually understanding how numbers work, how they work together, and why algorithms work helps students build a much richer understanding, and much greater numeracy.

Hear, hear. The sense that there’s reasons at play and hidden structure to be found, and the zest for the hunt, is at the heart of success in mathematics. Skill in standard mathematical manipulations is the blocking and tackling of the sport, the piano scales and chord progressions of the music. At some point, these skills have to become second nature if one is to “play” mathematics well. But they’re not the reason we do mathematics, and such skills do not, of themselves, make a mature, effective user of mathematics.

What matters at least as much is a feel for the flow of the game, of the music, for where it ought to go and how the answer might be teased out of the confused welter of possibilities that’s all one ever starts with. That comes from having had experience with toy problems that are not set-piece exercises. That comes from play.

Why do ravens play with wolves, even to the point of dancing near their snapping jaws? Because play is how they build the skill they will need when the day comes where they must grab their meals from under the jaws of wolves tearing into a kill. Play is how brains get good at unpredictable, open-form challenges. Play is not just “for the birds”.
