How Can I Teach Math If I Don’t Understand It?
Our childhood struggles with schoolwork gave most of us a warped view of mathematics. We learned to manipulate numbers and symbols according to what seemed like arbitrary rules. We may have understood a bit here and a bit there, but we never saw how the framework fit together. We stumbled from one class to the next, packing more and more information into our strained memory, until the whole structure threatened to collapse. Finally we crashed in a blaze of confusion, some of us in high school algebra, others in college calculus.
Homeschooling with Math Anxiety
Yet even parents who suffer from math anxiety can learn to enjoy math with their children. All it takes is a bit of self-discipline and the willingness to try.
- If you are afraid of math, watch your tongue: Don’t let a discouraging word pass your lips.
- Pretend like math is the most exciting topic in the world.
- Encourage your children to notice the math all around them — numbers, patterns, shapes, and symmetry.
- Curl up together on the couch to read a math book, or tell math stories at bedtime.
The secret to teaching homeschool math may surprise you: We parents need to learn how to think like a mathematician. Mathematicians avoid busywork as if it were an infectious disease. Mathematicians always ask questions, and most of all, they love to play.
We’ll look at each of these characteristics over the next few blog posts. If homeschool parents cultivate these mathematical ways of thinking, we will help our children to recognize and learn true mathematics.
Mathematicians Are “Lazy”
Mathematicians are not indolent, but economical with their time and energy. They have too many interesting topics to study and not enough time to learn about them all, so they cannot afford to waste their time on mindless busywork.
Mathematicians are always looking for a simpler way to do things. Skip counting is faster than addition; multiplication is even easier. Algebraic functions are shorthand ways to say things like, “Take any number you like and multiply by five, then subtract four and divide by seven and add one.” Calculus lets engineers solve problems that would be impossible without it.
To list out all the possible solutions to a problem may be impossible, so mathematicians invented special ways to think about counting. Permutations let us count the possibilities for when the order matters: “How many different ways might we award the 1st, 2nd, and 3rd place prizes in a race?” Combinations count the ways to do something when order doesn’t matter: “How many different three-person committees might we choose to plan the party for our homeschool co-op?” Both types of puzzle can be fun for middle school or older students.
Thinking like a Mathematician
When we look at education through the lens of mathematical laziness, we will be skeptical about the value of repetitive practice problems. If our children keep forgetting how to do certain calculations, perhaps they are not yet developmentally ready to learn them.
One of the biggest problems in math education is how often teachers train students to do “number tricks” the same way we would train a dog to fetch or roll over, by having them repeat the procedure until they can do it without thinking. Children will master the math better if we wait until they have developed a foundation that will help them understand why it works.
In the meantime, there are ever so many interesting ideas we can explore together. Homeschool parents who think like mathematicians will always make time for the fun stuff.
