## Kahn Academy

I have to take my hat off to Sal Kahn for a truly immense resource. What he has achieved with the Kahn Academy is nothing short of incredible.

He’s single handedly generated 1000+ instructional videos covering subjects including:

- Economics
- Finance
- Chemistry
- Arithmetic
- Pre-algebra
- Algebra
- Geometry
- Biology
- Trigonometry
- Precalculus
- Statistics
- Probability
- Calculus
- Differential Equations
- History
- Linear Algebra
- Physics

What a wealth of information. This has to be place in the category alongside Academic Earth and Udemy.

## MathTV

The site MathTV.com is brilliant on a number of levels. Firstly, if you’re a student and you want some area of maths explained via a simple, understandable video instruction then look no further. Areas covered are broken down into the topics Calculus, Trig, Algebra and Basic Maths, and then broken down further into multiple sub-topics. With many of the problems there are videos available by different presenters, come in languages other than English, including Spanish. To access these videos you don’t even need to register and log in. What could be simpler?

Additional to all that, if you are a maths tutor and you are wanting to set up a programme of maths to help with your students’ studies, you can create what is called a ‘Playlist’. You do need to register to access this facility, but the registration and login processes are simple and quick; as is the setting up of a playlist. Once your playlist is created, you are provided with a URL to access it, which you can pass on to your students.

Daniel Kopsas has created a screencast tutorial explaining how to set up a MathTV playlist.
