10 Good YouTube Channels for Math Lessons

Khan Academy has kind of become the default YouTube channels for people who are searching for mathematics tutorials. But there are plenty of other great math tutorial channels that students can benefit from. Here is my short list of YouTube channels not named Khan Academy that offer mathematics lessons. is developed by high school mathematics teacher Bradley Robb. His YouTube channel has more than six hundred videos covering topics in Algebra and Calculus. You can access the videos on a mobile version of WowMath too.

The New Boston which is primarily a channel for computer science lessons also has some good playlists of geometryalgebra, and basic mathematics lessons.

Math Doctor Bob's YouTube channel offers nearly 700 video lessons on statistics, algebra I and II, calculus, geometry, and much more. The lessons feature Doctor Bob giving the lesson in front of a whiteboard so you see him and don't just hear his lessons.

Patrick JMT offers high quality math tutorials. Patrick JMT doesn't cover as many topics as Khan or Math Doctor Bob, but the videos are equally solid. 

Numberphile is a neat YouTube channel about fun number facts. There are currently thirty-three videos in the Numberphile collection. The videos cover things like 998,001 and its Mysterious Recurring Decimals, Pi and Bouncing Balls, and 1 and Prime Numbers. I've embedded Pi and Bouncing Balls below.

Bright Storm is an online tutoring service. On their YouTube channel Bright Storm provides hundreds of videos for Algebra I, Algebra II, Trigonometry, Precalculus, and Calculus. Bright Storm also offers some SAT and ACT prep videos.

Ten Marks is another online tutoring service that offers mathematics tutorial videos on their site as well as on their YouTube channel. Some of the lessons in their playlists include lessons on units of measurement, decimals, fractions, probability, area and perimeter, and factoring.

Math Class With Mr. V features seven playlists made by a mathematics teacher teaching lessons on basic mathematics, geometry, and algebra. In all there are more than 300 video lessons. Like most mathematics tutorials on YouTube, Math Class With Mr. V uses a whiteboard to demonstrate how to solve problems.

The Open University is one of my go-to YouTube channel for all things academic. A quick search on The Open University reveals seven playlists that include lessons in mathematics. The lessons that you will find in these playlists are more theoretical than they are "how to" lessons.

Yay Math! features an excited teacher teaching mathematics lessons to his students. The videos capture just the teacher and his whiteboard with some feedback from students. The videos cover topics in Algebra and Geometry. You can check out the Yay Math! companion website to learn more about Robert Ahdoot, the teacher featured in the videos.

Santa Tracker and Related Google Maps & Earth Features

Once again Google has published their annual Santa Tracker website. The site displays a map of where Santa (if he was real) is traveling from his home at the North Pole. The Santa Tracker site shows you where Santa is in relation to your location at any given time. One of the neat educational tie-ins is that you can click on Santa's current location to learn more about that place. The location information is provided by National Geographic.

The Santa Tracker Christmas Traditions website offers a small collection of lessons about Christmas traditions around the world.

Outside of the Christmas season, use the Google Earth Flight Simulator to tour the world from an aerial perspective. The Google Earth Blog offers an extensive tutorial on how to use the Google Earth Flight Simulator.

Try the Collaboration Option in Triventy

Triventy is a free quiz game platform that I reviewed yesterday. One thing that I overlooked in writing my review is the collaboration option. As I mentioned in my post, you can mark your quizzes as public and let other users make a copy to use and modify in their own accounts. The part that I left out is that you can let students contribute to quizzes too. Learn more about this feature in the video embedded below.

Applications for Education
When Triventy's CEO reached out to me he suggested the following use of the collaboration option.
Teachers can invite students to add questions to their games. Typically, as a homework assignment before running the game in class. This creates a comprehensive learning experience – the students are both ‘players’ and ‘tutors’ who share their knowledge with the rest of the class.

A Couple More Skitch Alternatives

Last night I posted the news that Evernote is ending support for Skitch on iOS, Android, and Windows. In that post I shared a few alternative tools that I'm going to be using. This morning I awoke to an email and some Tweets suggesting some other Skitch alternatives.

My friend Rafranz Davis and a few others suggested using FiftyThree for iOS.

Kevin O'Donnell emailed me to suggest using Nimbus Screenshot and Screencast for Chrome. I just installed this extension this morning. One of the things that I immediately liked about it is the option to save my screenshots directly to my Google Drive account.

Triventy - Create Interactive Quiz Games to Play as a Group

Triventy is a free quiz game platform that I learned about from Larry Ferlazzo earlier this month. This morning was the first time I had a chance to actually test it out.

Triventy uses a concept that will be familiar to anyone who has tried Kahoot or Quizizz. To play a Triventy quiz game the teacher projects the game questions at the front of the room and students answer the questions on their mobile devices or laptops. Points are awarded for answering correctly. Bonus points are awarded for answering quickly. Students join the quiz game by going to and entering the game pin assigned to your game.

Creating a Triventy quiz is fairly straight-forward. You start by uploading a cover image. Then you can begin adding questions to your quiz. Questions are written in multiple choice format. You have the option of not awarding points for questions by selecting "survey question." If you want to build hints and explanations for questions, Triventy has a field for that at the end of each question. Images can be uploaded for each question. You can mark your quiz as public or private. Public quizzes can be seen by other teachers who can use them and modify them within their own Triventy accounts.

Applications for Education
One of the neat features of Triventy for students is that they can ask for a hint or to have an answer choice eliminated. Students can also see an explanation of the answer to each question.

One of the drawbacks to Triventy is that there doesn't appear to be a way to save quiz results. I also didn't see a way to moderate names that students enter when they start to play a Triventy quiz game.
