This year I have a wonderful opportunity. I get to teach math. Specifically, I teach middle school students in an algebra class and elementary and middle school teachers during professional development in an effort to build their mathematical capacity. I honestly love my job.

While these adolescents and adults are fairly different in their temperaments and instructional needs, they both have challenged me with the essential question: Why do we need to learn this stuff?

REASON # 1: Mathematics Is a Practical Tool

I’ll start with the common assumption. Mathematics is a practical tool for many of the tasks we have to complete in our daily lives as well as in most if not all jobs. Mathematics is relevant in our daily lives when we calculate the tip and how to split the bill when we eat out with a group of friends, when we figure out how many gallons of paint to buy to paint that room, or when we ignore the odds and go ahead and buy that lottery ticket anyway. Math is useful.

In addition, we are experiencing a resurgence of calls for improvement in science, technology, engineering, and math education (STEM as it is called). Much of the rationale for this resurgence is couched in economic terms. As this argument goes, we live in what Thomas Friedman has coined a flattening world, and if students in the United States are going to be able to continue to compete in the global marketplace they need math. The types of white collar technical jobs that will pay a living wage require a high degree of mathematical proficiency because math is a practical tool. Jobs in fields such as finance, accounting, economics, statistics, computer science, engineering, chemistry, and physics require a high level of mathematical proficiency. In addition, as information technology advances, jobs in every other sector will require increasing levels of mathematical know-how.

All of this is true. However, this reasoning only views mathematics as a tool. From this perspective, math is no better than a very versatile hammer. It is a means to an end. The problem with only viewing math from this lens is that for many of us it means that we could learn some elementary computation, a bit of measurement and geometry, and possibly a bit of probability for parlor tricks on the weekend, and be done with it. Many of my students rightly ask, “when will I use all of this analysis of linear equations in my daily life?” And if the only view of mathematics is as a tool, I have to admit that those who don’t go into a math-related field won’t ever need to find the slope of a linear pattern. However, I would argue that it is still important for them to study how to generalize and analyze linear patterns. Here’s why.

REASON # 2: Mathematics Cultivates Habits of Mind

Regardless of the mathematical content you learn, the study of mathematics cultivates habits of mind or thinking skills that are powerful disciplines for negotiating our world. At the heart of good mathematics instruction is problem solving. To do math effectively, students need opportunities to learn how to struggle through and solve ill-defined problems. This process teaches perseverance, how to communicate an idea precisely, how to build a reasoned argument, how to think flexibly, and how to be metacognitive, or to monitor their thinking and problem solving process. These skills are not unique to mathematics, but are skills that are relevant to the process of solving any problem in any area. So, whether a person is destined to use calculus in their daily life or work, the study of calculus can build in them the skills to tackle whatever problems they face. Mathematics is uniquely positioned as a part of the core curriculum of our schools to help build these skills.

However, this aspect of mathematics might only be useful to a person during their school years, and could easily be left behind. If you don’t particularly like doing math and find it difficult during your school years, you can easily choose a career path that isn’t dependent on mathematics. You will still have gained the benefits of cultivating habits of mind for solving problems, and you will go on to apply them in other areas. Which brings me to my third reason for learning and doing mathematics.

REASON # 3: Mathematics Leads to a More Satisfying Life

Mathematics as a system is one of the most beautiful and enduring creations of the human mind. Developing understanding of mathematics is learning to appreciate and contribute to this work of collective human ingenuity. Over the course of human civilization, mathematics has developed as a tool for organizing our complex social lives as well as understanding our universe. Specifically, as the science of patterns, mathematics finds connections between often disparate phenomena and explains how those phenomena behave in surprisingly similar ways because of mathematical patterns. Furthermore the whole of the mathematical world that describes these patterns was not invented or discovered by a single individual but by the collective work of millions of mathematicians striving for understanding. Knowing this provides inspiration for my own explorations in the world of math. While there have been many great individuals who have made monumental contributions from Euclid and Archimedes to Newton and Gauss, mathematics as a whole is the work of many. Each of us has the potential to contribute to this work.

With this realization and a little mathematical knowledge, everyone can open doors to understanding our world that are shut without mathematics, but don’t take my word for it. Watch the short video Nature by Numbers created by Cristobal Vila for Eterea Studios.

Truly, as mathematician Jerry P. King wrote in his book The Art of Mathematics “… one’s intellectual and aesthetic life cannot be complete unless it includes an appreciation of the power and beauty of mathematics.” If we are serious about educating our children to be active participants in their own education and responsible and compassionate members of society, then they must have access to a mathematics education that not only teaches the powerful tools that mathematics has to offer, but also opens them to the possibilities of beauty and wonder that only mathematics affords.
