Math Videos for Middle & High School

Brightstorm: Math: Free Online Math Videos


Grades 7 & up, with parental supervision

Brightstorm is a company that finds and films the best math teachers and creates engaging lessons around those teachers’ videos. The company sells test preparation programs, however, as an outreach to new customers, they offer over 2,000 FREE videos that teach math from Algebra through Calculus.

For example, as an Algebra student, you can watch a series of lessons on quadratic equations and functions. In each lesson, the concept is explained. Then, the student is presented with three more videos that present problems and explain solutions.

The lessons I watched were taught by a quirky and charming young woman instructor with a unique style and flair for teaching math. (Don’t miss her demonstration of setting “The Quadratic Formula” to the tune of Pop Goes The Weasel.)

When you get to the site, use the “Subject” menu to select the math topic of interest:

  • Algebra
  • Geometry
  • Algebra 2
  • Trigonometry
  • Precalculus
  • Calculus

Click on any one and a new window opens with a menu of topics in that category. Click on the topic of interest to access the lessons. When you click on a lesson, the first video in the series will launch, but you will be required to register (it’s free) to watch the entire video. Registered users can watch as many math videos as many times as they like.

As the website explains, “The power of a great teacher in action is undeniable.” Thanks to technology, students can learn math from some of the best teachers available – wherever and whenever they want.

Endless Math Quizzes at the Click of Your Mouse!

That Quiz


Grades 2-12, with parental supervision

If you are interested in no-frills online math practice, this website is for you. It will generate endless math problems for you to try, and instantly tell you whether your answer is correct.

There is a teacher registration (free!) and login option, and students can log in to see what work their teacher has assigned them, but this is a help for classroom teachers with multiple students and scores to keep track of; individual students don’t need to register, and most homeschool parents/kids won’t need to either; everything on this site is accessible without registration.

There really is something at every level here: a whole decade’s worth of randomly generated math practice problems on one deceptively simple-looking website. For each activity, be sure to look in the left-hand column to select the parameters you’d like to apply. For example, for calculus, you can choose to practice integrals or derivatives. For fractions, you can identify the given fraction from the visual representation, or fill in the number of rectangles to represent the given fraction, and you can also select the level of difficulty. You can choose to practice only ten problems, or as many as a hundred. It will keep track of your score, and give that score to you as a percentage after you finish the set of questions. What you will not find here are cute cartoon characters, cool sound effects, advertisements, bright colors, animation, or anything flashy. You might find it helpful to keep some scratch paper and a pencil handy; write down the problems that you miss so that you can figure out what you did wrong.

This website is also available in 10 other languages! Just click the Language title in the bottom left corner of the front page.

Note: With some of the activities, a message appears stating that you might need to download an updated browser; however, if your browser is already up to date, the message goes away when the activity has finished loading, and the activity works just fine.

Simpsons Math Activities


Age Range: 10 and up (Grades 5 and up approximately; parents should preview and supervise)


In many episodes of the popular animated sitcom, The Simpsons, there are references to mathematics including arithmetic, geometry, and calculus that uncover and poke fun of mathematical illiteracy. As explained at the website, “Al Jean, Executive Producer and head writer, has a bachelor’s degree in mathematics from Harvard University.”

Two math professors saw the potential to use math references in The Simpsons as an “ideal source of fun ways to introduce important concepts to students, and to reduce math anxiety and motivate students…”

When you get to the site, you’ll see a brief introduction, followed by a menu that includes: 

  • Mathematics on The Simpsons – Read a few articles that reveal where and how math is used in various episodes.
  • Engaging Students with Related Mathematics – Get free “Activity Sheets” based on math references in random episodes of The Simpsons. They are designed for classroom use (but can be tweaked for homeschooling) and cover concepts such as: 
    • The Pythagorean Theorem
    • Arithmetic and Number Theory
    • Pre-Calculus and Calculus
    • Probability

You’ll also find links to media coverage in which the writers and other crew members talk about the math and science in The Simpsons‘ episodes. And there are suggestions and cautions for teachers about using pop culture in the curriculum as well.

BONUS! Mathematics on Futurama! That’s right, the science fiction cartoon series has math and science references in almost every episode. One of the comedy writers on Futurama! has a Ph.D. in applied mathematics from Harvard and you can read about his “inside jokes” in various episodes. The site is similar to The Simpsons math site, and contains free Futurama! math worksheets.

Note: While these programs may be pop culture icons, some contain controversial subject matter. As always, parents must preview the material and supervise Internet access.
