Math, Electricity, & the Creator

electricity

I’m excited to have just finished the draft of a full-color, 8.5 in by 14 in by 15 ft math timeline, on which students will be able to watch math in action throughout history—and see how math points us to the Creator in the process. Below is a sneak peek into just a few of the facts students will learn. Stay tuned for publication information!

Electricity—we take it for granted and use it countless times a day. Turning on lights, using a computer, microwaving those leftovers, looking at a digital clock, cranking down the AC, opening the refrigerator, doing a tub of wash—the list of daily uses of electricity or electrical devices could go on and on.

But did you know it’s math that helps us explore electricity and design devices like lights and computers? A glance back at history reveals a lot of math—and points us to the Creator.

Back in 1785, A man named Charles-Augustin de Coulomb discovered a mathematical relationship between the force and distance between electric charged particles by doing experiments. His result can be expressed algebraically like shown below.

In other words, the force produced by electricity can be described mathematically!

Michael Faraday

Later, many other men would do experiments and discover more of the ways electricity works. One key discoverer was a man named Michael Faraday, who realized that magnets can generate electricity and invented the first electric generator. Once again, math was used in this design. In fact, the relationship between the electrical voltage, the number of coils of wire, the change in something called magnetic flux, and the time can be described like shown below.

Faraday, like many other great scientists/inventors, saw creation (which math helped them explore) as pointing to God. Faraday wrote,

“The book of nature which we have to read is written by the finger of God.”

Sit back and think about it for a minute. Even at the microscopic level, electricity (which later scientists would realize is the flow of electrons) operates in a consistent enough fashion to describe it with formulas that we can rely on to work to such a degree that devices like light bulbs and computers can be built around it. Why is creation that consistent? Because a faithful, consistent Creator governs all things.

Don’t Lose Sight of Math’s Usefulness

math

It’s easy in anything we do to forget why we’re doing it. In math especially, it can be easy for students to lose sight of why they’re learning what they’re learning.

As you head back to school this fall, remember to keep bringing math out of a textbook and showing its usefulness. Below are a few ideas.

Grade School

  • Play store by putting masking tape price tags on toys. (Make the costs children are learning–for example, a toy might cost 24 cents or 14 cents. There’s no need to write it out with decimals yet–24¢ works.) If teaching place value, have them figure out how many dimes and how many pennies are needed (for 24¢, that would be 2 dimes and 4 pennies). If working on addition, have them total up how much several toys would cost. If working on subtraction, figure out the change they’d need to give if you gave them a certain amount of money. Adjust the amounts to match the type of problems they’re working on. You can even sometimes let them use a calculator to practice inputting numbers…and to emphasis how, because of how faithfully God governs creation, we can memorize facts (or input them into a calculator) to make addition and subtraction easier.
  • Incorporate math into play. If your child likes to play with stuffed animals, play act a scenario where some animals go missing to illustrate subtraction. If your child is into blocks, make up a scenario where the block guy is given some extra blocks to illustrate addition. The possibilities are endless. If your child is into bugs, have them measure some bugs. If into playing princess, have a scenario where extra lumps of sugar get added to the princess’ cup.
  • Point out ways you use math in daily life–even if it’s something simple like setting the air conditioner’s or oven’s temperature…or measuring ingredients for dinner.

Junior High and High School

Students at this level now have the background knowledge to delve into some really cool applications and to see at a deeper level how we use math to describe God’s creation! Pay attention to percentages in the news. Capitalize on different science concepts they’re studying, pointing out the math involved (the Internet is a great resource to research–or have them research). Explore the math used in fields of interest to them. The possibilities are truly endless.

Geometry from a Biblical Worldview (New eCourse Available)

mountain/stars

Despite how it often comes across to high school students, geometry is anything but meaningless. In fact, geometry means “earth measure.” It’s a branch of math that helps us measure God’s creation, from the microscopic to the vast distances of space.

I recently had the privilege to develop a geometry eCourse (available on MasterBooksAcademy.com). While it was the most challenging eCourse I’ve developed (creating slides to visually walk through proofs involving different shapes step by step required more than just walking through equations), it was also the most fun to work on. I was blown away over and over again by how geometry sings the Creator’s praises and proves a useful tool. Here are some examples, based on Harold Jacobs’ Geometry: Seeing, Doing, Understanding curriculum and the eCourse I developed to go alongside it (the eCourse both walks through the material and expands on the ideas in the textbook to really bring in the biblical worldview as well as to help students master the concepts without being overwhelmed by the challenges).

mountain/starsGeometry and God’s Creation

Did you know that geometry was used to find the circumference of the earth…and the distance to the nearest star? The distances of outer space are mind-blowing in themselves—yet how much more incredible the God who stretched out the heavens (Isaiah 42:5)! Geometry helps us describe the arrangement of molecules; did you know if the molecules in our bodies were just mirror images of what they are, life as we know it wouldn’t work? Geometry shouts out that life didn’t happen by accident. Geometry helps us see the design in our eyes, and how God gave us the ability to perceive both distance and depth. With geometry, we can measure the height of things we can’t physically stretch a measuring tape to measure—such as a mountain or a tree.

cell phoneGeometry and Real-Life Tasks

Not only does geometry help us explore God’s creation, but it helps us complete real-life tasks. It helps us design bridges, make beautiful art, and engineer chairs, to name a few. Geometry proves a wonderful course to talk about how God made man in His image and how we’re accountable to our Creator for how we use the intellect and abilities God gave us (a great theme to explore in high school as students are thinking through their futures). On a daily basis, we all experience the effects of geometry applied for both good and evil. Every time we use our cell phone, we’re using cell networks that are really a grid of “hexagonal cells” (Jacobs, p. 583)…and we’re using that device for either good or evil.

Geometry and Apologetics/Logical Thinking

While proofs are definitely a key part of geometry, they too are a useful tool. Proofs help us figure out if something applies just in one situation or in all, making them essential in describing God’s creation. After all, if we’re going to use geometry to measure distances in outer space where we can’t physically check our measurements, we need a way to think through those measurements logically. Deductive reasoning is thus a key piece of geometry—and it applies in other areas of life too. In the eCourse, students learn how in any proof, we start with assumptions—and the conclusions we reach are only as valid as the assumptions we begin with. This is key to understand when discerning through arguments people make (and when making them). For example, if you assume a uniformitarian perspective for how a canyon was made, you will reach different conclusions than if you assume a catastrophic global flood was the cause.

Conclusion

Don’t let geometry fool your students: it’s really an exciting journey through which we can behold God’s handiwork and get equipped to serve Him each step. While geometry can feel like a whole new world for students as it’s very different than arithmetic or algebra, understanding its purpose can help students push through the challenges to learn the key skills that really apply outside of math as well.

If you’d like to learn more or need a resource that teaches geometry from this perspective, check out the geometry eCourse I developed on the Master Books Academy. The first chapter is free to watch, and it will give you a greater glimpse into how geometry, far from being a meaningless exercise, is an incredible journey into measuring the earth.

Summer Math Ideas

summer

Looking for ways to keep math fresh during the summer? How about to use the summer to help students grasp some concepts that just haven’t fully sunk in yet?

Summertime can be a great time to really give students a glimpse into math outside of a textbook, to build their biblical worldview of math, or to give some added practice on different skills. Below are a few ideas to help.

  • Summer Projects and Problem-Solving Skills – A great way to help your students learn problem-solving skills is to give them opportunities to use math outside a textbook, guiding them through figuring out what information they know, what they need to know, and what steps they can take to get from one to the other. This previous blog post gives some ideas of how you might do that as you live life this summer.
  • Glimpses of Math in Action – Explore how math applies in different industries of interest to your child–or in helping us explore God’s creation. NASA has a whole section of resources on their website that shows many applications in exploring the heavens; only note that they are not from a biblical worldview, so you’ll want to use them as a discernment discussion too. For example, this No Small Steps video gives a fascinating look into the “brains” behind a SLS rocket. It would provide a wonderful opportunity to talk about how MUCH work went into designing the rocket…and how MUCH more powerful our own brains are too. There’s no way a rocket would assemble by chance…nor is there any way our brains did!
  • Firming Up the Basics & Worldview Building – Summertime could be a great time to go back over concepts students have studied and review them, building their biblical worldview in the process. Revealing Arithmetic: Math Concepts from a Biblical Worldview is a resource I wrote that has both the biblical worldview of and ideas to reinforce arithmetic concepts (counting through exponents and roots). One idea is to go through a chapter of it a week, picking one or two of the ideas listed there. (Ideas include things like playing games together, included worksheets, everyday life examples, hands-on activities, etc.) With older students, you can have them read the chapter themselves and pick an idea. There’s even a video eCourse you could use; if the student has already learned the basics of the concept, you can have them watch the videos with you as a way to review.
  • Keeping the Facts Fresh – There are a variety of online worksheet generators you can use to generate worksheets your child can use to review math’s mechanics. We’ve got a list of some on our Principles of Mathematics Book Extra’s page.

I hope you have a fun summer together!

New Algebra 1 eCourse

Algebra 1 eCourse

I’m excited to have just finished an eCourse to go alongside Jacob’s Elementary Algebra!

The course, which is now available as part of the Master Book’s Academy, brings in the biblical worldview of math, presents the concepts, walks through examples, and more, offering an easy transition from Principles into high school math.

Learn more and view a sample chapter at the Master Books Academy.

P.S. I’m sorry I’ve not blogged much recently–it’s been a busy time! My husband and I just moved into our first home. We’re also still working on Algebra 2 (we expect it to be finished within a few months)…along with other math projects (stay tuned for more details in the upcoming months).

Making Math Come Alive During the Coronavirus Sheltering in Place – Plus Drill Worksheets

With much of the world sheltering in place, I thought now might be a good time to blog about working on math during the downtime. These ideas also work during summer vacation…and throughout the year.

Show Your Child Math Around the House

Look for simple ways to show your children math concepts in action around the house. Here are a few ideas.

  • Baking can use fractions—including multiplying them if you halve or double a recipe.
  • Many games use basic counting and number skills—especially if you have your child be the score keeper or banker. They can also provide an opportunity to talk about probability with older students.
  • Finance skills can be taught by using the down time to show your child how you keep a budget or balance a checkbook.
  • Crafting uses various math skills. Making cards, sewing, woodworking, etc., involves working with fractions in measuring out the materials.
  • Music involves fractions; after all, we use quarter notes, half notes, etc.!

Revealing ArithmeticAs you show your children math in action, remind them that math works outside of a textbook because God created and sustains a consistent world.

For more ideas of how to reinforce arithmetic concepts, take a look at Revealing Arithmetic. It explains how to look at each concept biblically (and why different methods work!), offering many practical real-life ideas (along with a few worksheets) you could use with your children to show them the concept in action. Many of these ideas (such as designing and using an abacus) would make great (and fun!) shelter-in-place activities.

Use Worksheets for Trouble Areas

I’m cautious about publishing a list of drill worksheets, as while drill worksheets have their place, there’s a problem if math becomes only about fact memorization or drills. Students need to see why they’re learning what they’re learning and have opportunities to really apply the concepts they study outside a textbook! Drill worksheets are like scales and technique exercises in music. They help students master a skill, but they’re not a song. And just like most students would hate practicing music if all they played were technical exercises without any songs, so most students will hate math if all they do are drill worksheets.

Nevertheless, math drills serve their place. Some students need extra reinforcement on specific problem areas. (Although make sure they really understand the concept before throwing too much drill at them; sometimes students struggle to remember because they don’t really understand why the method works or why they need to learn it.) With that in mind, here are some internet resources for printing out worksheets.

  • Math on the Level ($5 monthly or $35 yearly fee) – Developed by a friend specifically with homeschoolers in mind, 5-a-Day-Review Online Essentials will custom generate problems based on your choices of skills that need tested. A list of the concepts it covers can be found here. While designed to go alongside the math program the company sells, the software would really work for any elementary through pre-algebra program. The beauty of this program is that it lets you pick different skills—you can review fractions, finding the area, and addition all in one worksheet, for example—and specify exactly what aspect of each to review! And the software will often be able to combine concepts into one problem, meaning your students can keep more skills fresh in their minds without a ton of busywork. Easily customize a completely tailored worksheet–and print out the answer key too!
  • IXL Math – I appreciate how this site is organized. You can find problems by topic or by grade (spanning all the way from pre-K to calculus!). Rather than worksheets to print, these are online interactive problems; if a student gets one wrong, the system will tell them (and explain why).
  • Worksheet Works Worksheet Works offers a variety of slightly customizable worksheets on a variety of topics. Note that some worksheets require a $14.95/year membership.
  • Math Drills Math Drills offers just what the name implies: math drills. These are a bunch of free, old-fashioned printable drill sheets. There does not appear to be a way to customize them, so it may take you a bit longer to find what you need—and you might not need to have your child complete the whole sheet (depending on how many problems you felt they really needed to solve).

Again, please remember to use drills like you would technical exercises—in small doses to help strengthen skills, not as your main teaching device. Please see the first section above for ideas on actually helping students see why they should bother mastering math’s mechanics. If all students see are the mechanics, they’re completely missing out on understanding math as a way of describing God’s creation and a real-life tool they can use to serve Him. And, to return to the music illustration, they might just decide they hate math, only because they’ve only seen the “exercise” part of math without ever getting to “play a song.”

Exciting Announcement: Algebra 2 Is Coming!

algebra

Several years ago, I was asked to write an algebra program…and I said no. I wasn’t going to write a high school program unless the Lord sent me someone to coauthor it with me.

And then he sent me my husband, who has his doctorate in materials science and engineering, other degrees in physics and engineering, a job as a data scientist, and a passion for sharing God’s handiwork in math that mirrors my own. So…

We’re writing an Algebra 2 program! Principles of Applied Algebra 2 (working title) is well underway, with an anticipated release in the spring 2020, Lord willing. (We’re doing Algebra 2, as it was the more urgent need. Please see the Algebra 1 program we carry.)

Writing this program has been exciting. I was one of those students growing up who didn’t understand the purpose of algebra—I learned it, but didn’t see why I was learning it. Most algebra books come across as a whole bunch of meaningless, often hard-to-understand problems.

But algebra doesn’t have to be that way at all! I’ve been having loads of fun researching the different “tools” in algebra and seeing how they all really help us explore God’s creation and complete real-life tasks…and then conveying that in the program. We want students to leave their math lessons for the day understanding why they’re learning what they’re learning, equipped to really apply math, and awed at the Creator.

Ready for a sneak peek? Watch for an excerpt sometime next week!

We would cherish your prayers for us as we write.

Choosing a Math Curriculum

So…it’s that time of year again. Time when many anyway start thinking about heading back into academics…and math.

Wherever I’ve spoken on math, the number one question I usually get is related to curriculum. So I thought it might be a good time to share a couple of thoughts on choosing a math curriculum.

  • Look for one that shows math as a practical tool. 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 which lead nowhere.” Not only that, but unless students see a purpose to math, they’re left viewing math as some sort of man-made or self-existent truth rather than as a real-life tool that helps us describe God’s creation.
  • Look for one that really helps student understand why the rules in math work. While there’s a place for memorization, it’s also important that, at whatever level a student can developmentally, they understand that the rules in math are not arbitrary but really are simply shortcuts to help us describe the principles God created and is sustaining.
  • Look for one that incorporates history. History goes a long way towards helping students see math in context and understand that the symbols they’re learning aren’t math itself, but rather a language system that help us name the quantities and consistencies around us. They’ll also see how mathematicians have used their God-given ability to solve real-life problems…and be able to see the role worldviews have played.

On a more personal level, also consider

  • the level of parental involvement. Is it manageable for your schedule?
  • the style of the material. Does it present it in a format your child can work through?

Finding a good math curriculum can be challenging. The need for more good math curriculum prompted me to write a math curriculum for junior high (Principles of Mathematics), along with a handbook (Revealing Arithmetic) to go alongside a curriculum the younger grades and add the elements that are often missing in curriculum (such as history). We also carry an elementary and high school program that many have found helpful. So know that those materials are available for you too.

Whatever curriculum you choose, remember that math isn’t neutral or a mere textbook exercise–it’s a way of describing God’s creation. And viewing it that way should transform how it’s taught at every level.
