I’ve known about the free math resource – Khan Academy for a few years now, but just this month I checked it out again. Right away I noticed the tagline said over 38 million lessons delivered, and each time I refreshed the page, that number was updated. Today, the site hit over 40 million lessons. A few million lessons served in just a few weeks, wow!

This is an ASTOUNDING, AMAZING, ASTONISHING resource of 2000+ 10-minute (give-or-take) videos, mostly on math, but also on science and much more! They are easy to learn from and did I mention free?

The thing that caught my attention this month was that you can now login with your Google or Facebook ID and it will track your participation with Energy Points. You can earn points and badges from watching videos and doing your exercises.

I went through all the easiest Arithmetic videos and exercises and now almost done with Pre-Algebra. I will for sure be using this as a math and science supplement for Satori!

I could take all my own screenshots to show you, but it’s best if you just watch through his explanation video. I’m not sure this YouTube video will fit within my blog, if it doesn’t all show, just head here:

Bill Gates is a huge fan – he uses Khan Academy for himself and his children. Khan Academy was also one of the first winners of the Google $10 million dollar award for Project 10^100, a global search for ideas that would “help the world the most”. What did Sal do with his $2 million from that? He turned right around and put that toward translating his videos into other languages, so even more of the world could benefit from his videos. Sal now works on Khan Academy full-time and has added a staff of six.

No matter if you homeschool, afterschool, or don’t even have children, you can use Khan Academy for yourself and/or your children to get up to speed on math. Since I’ve been watching these videos, I’ve become very psyched about math. I think you’ll see a big math focus in our household this spring.

Salman Khan is my hero!
