A Couple Great Video-based Mathematics Websites

My wonderful friend Patti sent me links for two websites that contain hundreds of short video tutorials on a huge variety of mathematical concepts. Emily had expressed a desire to learn more math, and not being the kind of homeschoolers who sit down regularly for math lessons out of a specific program, this is just what we needed! I'm going to be able to brush up on what I've forgotten, or never learned in the first place, and also have better tools to explain the "whys" of specific math functions.

The first one is called the Khan Academy. From the site:

The Khan Academy is a not-for-profit organization with the mission of providing a high quality education to anyone, anywhere.

We have 700+ videos on YouTube covering everything from basic arithmetic and algebra to differential equations, physics, and finance which have been recorded by Salman Khan. He has also developed a free, adaptive math program available here.

To keep abreast of new videos as we add them, subscribe to the Khan Academy channel on YouTube.

The math concepts on Khan Academy run from Basic Arithmetic through Calculus, and also includes Finance, Physics, Banking and Money, and more. All free.


Then there is MathTV.com. They don't have any information about who they are; their FAQ is "coming soon." But they, too, have video clips of people explaining a large variety of mathematical concepts, from basics like fractions and decimals up through calculus. If you need videos on multiplication and division, they don't have anything at that level, however.

I checked out their videos under Algebra: Exponents: Division with Exponents. (They have two different people do the same problem.) WOW! I don't remember any of that stuff! Must have gotten through it, in about the year 1983 or so, but it's long gone. ;) And as far as I remember, I've never had to use it since graduating high school. Not to say that it's not worth learning if you're interested, and you certainly need to understand it to proceed in math; but for everyday use, uh-uh. It's nice to know i can "re-learn" it if I ever need to, though.

If you have found any great sites with videos explaining language arts, please leave a link in the comments!


Update:

I received an email from Patric McKeague at MathTV:


Hi Silvia,

Thanks for the link on your blog. here is the contents of a press release we recently sent.

Best , Patric McKeague

News release: 4,000 free online videos help math students 24/7

Leading Textbook Author Has 4,000-Plus Online Videos to Help Math Students 24/7

SAN LUIS OBISPO Leading math textbook author Charles P. McKeague has produced over 4,000 online videos, allowing students to get help with math any time, day or night. And at MathTV (www.mathtv.com), all instruction is free.

The site offers a variety of instructors -- including one who speaks Spanish -- working problems from basic mathematics and beginning algebra to trigonometry and calculus.

McKeague, co-founder of MathTV, is a popular textbook author, teacher and frequent guest speaker at mathematics conferences throughout the country. He is author of the popular developmental mathematics series Basic Mathematics 7/e, Prealgebra 6/e, Beginning Algebra 8/e, and Intermediate Algebra 8/e. His textbooks are published by Cengage Learning, one of the leading publishers of college textbooks worldwide.

Currently 80 percent of the topics in the textbook series have correlating instructional videos. To give students a more classroom like experience, MathTV includes mini-lectures by McKeague, study skills videos, enrichment videos, and common mistakes videos. By summer McKeague expects to have 5,000 videos available free online.

MathTV will launch its premium service later this year, which will include online textbooks "Introductory Mathematics," "Elementary Algebra," and "Intermediate Algebra," to be published by MathTV. "My goal with the online books is to offer students and instructors a low-cost alternative to print books," McKeague said. "I am in a position to decrease the cost of textbooks without sacrificing quality."

For more information, contact McKeague at 805-541-4593 or pat@mckeague.com or visit his Web site at www.mckeague.com.
