I recently asked some folks this question:

What are you/your children’s biggest struggles in math?

The responses varied (stay tuned for others in future blogs), but several voiced the same struggle: *why.*

Knowing *why* you need to learn something certainly doesn’t seem like too much to expect. It’s actually a very reasonable question. As Alfred North Whitehead said, “There can be nothing more destructive of true education than to spend long hours in the acquirement of ideas and methods that lead nowhere.”

So why math? Well, math is a way of describing the consistent manner in which God holds His creation together. Thus it helps us work with the world around us—from everyday tasks to sending men to the moon. It helps us complete various tasks that God gives us to do here on earth.

For example, **fractions** give us a handy way of describing division, helping us work with real-life relationships. Oh, and don’t forget that music notes, sewing, and cooking all use fractions! (There’s more on the *why* of fractions in my previous post “Why Learn Fractions?”)

One mother shared that her child wondered *why* finding the area of triangles matters. While **triangles** might not at first appear to be the most practical shape, they can actually help us measure such real-life distances as the height of a building and the distance across a stream. (In fact, that’s exactly what students learn to do in *Principles of Mathematics* while studying triangles.) As for finding their area, triangles also help us measure other shapes. For example, if we want to find the area of a hexagon (which is what bees make their honeycombs out of), we would use triangles to do it. Triangles—along with the rest of geometry—are incredibly practical!

For those of you wondering the “why” of **high school math**, I recently had an article published in The Old Schoolhouse magazine on that exact topic. You can read “What’s the Purpose of High School Math?” online (note: it may take a minute to load)…and I’d love if you’d then leave a comment here and let me know what you think.

And for those wondering how to teach math in such a way that your students will understand why they’re learning each skill they study, **check out the math resources **I wrote specifically to help students understand math’s true purpose…and to praise the Creator of all as they study. After all, math applies because Jesus is upholding all things by the power of His Word (Hebrews 1:3) in such a predictable way that we can describe it mathematically! Math, when properly taught, should encourage us to trust Him more and more.

*Have a specific math topic you’d like to know the “why” of? Leave it as a comment!*

After having her own view of math transformed, Katherine has been researching, writing, and speaking on a biblical worldview of math for more than a decade. Her books on math and a biblical worldview have been used by individuals, homeschool groups, and Christian schools and colleges, and she recently finished a junior high math curriculum.
