Best Online Math Courses

Some people seem to have a natural affinity for math. If that’s you, great! Others, however (like myself), may struggle from time to time with certain concepts or procedures.

Because of this, I have curated this guide on the best online math courses in 2021 for complete beginners all the way through to advanced.

Some of the topics covered in these courses are basic adding, multiplying, division, subtracting, fractions, percentages, algebra, and heaps more! Let’s get started!

Top 11+ Free Best Online Math Courses, Classes & Certificates 2021


1. Mathematical Fundamentals (Brilliant)

Mathematical Fundamentals Brilliant Learn How To Get Great At Arithmetic With [year]'s Top 11+ Best Online Math Courses & Classes

I have to start our list with Brilliant.org. They are pretty new to the game, but they are changing how kids and adults can learn math online.

Here is what sets them apart. First, they have an in-depth curriculum that starts as early as middle school algebra and moves all the way up through the advanced mathematics more common in university. Think Statistics, Quantitative Finance, and Differential Equations. So if you like this platform, it can grow with your student.

Second, the visual simulations are both beautiful and unlocking. Instead of learning math through brute force repetition and memorization, they take you on a journey with smart visuals that teach you increasingly complex concepts you can then apply to solve problems. Each visual builds on the next with understanding checks at each point.

This is so much less frustrating than parents who learned “the old way” trying to teach kids who are learning “the right way.” I’m looking at you, Common Core. And you Singapore Math.

But seriously, this process helps build a real STEM intuition that will help kids excel in today’s increasingly technical world.

Finally, there is instant feedback, so you know if you nailed the concept. And if you didn’t, the explanations offer another angle to help you understand. I know at least one middle-schooler who liked seeing the percentage of other students that got each problem right or wrong. There is nothing like a little daily gamification to keep school-aged kids locked into learning.

You can get started on the platform for free by registering with an email. This will give you access to the basic math courses, as well as science and computer science. You can also upgrade for access to their full library of courses and get 20% as one of our readers.

Given you can start for free, and so many families are looking for supplemental help with math, we think it’s one of the best online math classes for kids available today. We’ve also done an in-depth review of Brilliant if you want to learn more.
