# 5000 free math, physics, and engineering video tutorials and lectures

Here are the collections of sites with math, physics, engineering, and other sciences video tutorials. Some sites also contains non-science videos as well. If you find a site with more than 50 videos, please inform me so I could include it on the list. Khan Academy – more than 2100 2600 not only for math but also includes other subjects such as economics, chemistry, physics and other fields.
Math Apps for the iPhone, iPod Touch, and iPad
Yesterday, while browsing through the app store on iTunes, I came across a banner-style ad at the top of the page for apps that help you to learn math. I found this feature very helpful and decided to browse through some of the apps. The topics were broken down into sections including Numbers & Operation, Geometry, Algebra, Calculus, Probability & Statistics, Applying Math, and Math Games. The important factors that you should consider when buying an app to use is price, quality, interactive ability, and be sure that it is engaging and easy to use. iLiveMathSpeed iLiveMathSpeed is one of a series of iLiveMath apps provided by iHomeEducator. If they want to learn more about a topic, they are able to choose to go through to a kid-friendly browser that links to the terms based on the transportation and math covered the program. The newest version of this app has larger buttons to pick the various options and answers in the activity to help special needs students. 115-in-1 Math Solver

Professional blog | 21st Century Educator
Here are some tools which I've either used (or explored) for mathematics education. They aren't all open source, but they are all extremely useful, and they are all free to use (free as in free beer, some of them are also free as in free speech). Geogebra This program lets you explore algebra and geometry, much like it's proprietary cousin, Geometer's Sketchpad. Mathematics Visualization Toolkit The Mathematics Visualization Toolkit is exactly that, a program which lets you visualize mathematics. Scratch Scratch is an excellent program for learning programming but also mathematics like variables, sequences, Cartesian coordinates, and other useful mathematical concepts. Netlogo Netlogo is "a multi-agent programming modelling environment" (According to the Netlogo website). Audacity Audacity is an open source audio editor and recorder. Calculize Calculize is a free (currently) web app which lets students perform mathematical computations using a reasonably simple programming language. Desmos Logo

Storyboarding: Pre-Writing Activity
The more we podcast and have our students create video clips or other digital storytelling projects, the more we need to teach storyboarding as part of the process. Being able to pre-visualize how your story will unfold is becoming a vital skill to have for storytellers. Storyboards are defined as: Graphic organizers such as a series of illustrations or images displayed in sequence for the purpose of pre-visualizing a motion picture, animation, motion graphic or interactive media sequence, including website interactivity. In the book by Roger Essley “Visual Tools for Differentiating Reading & Writing Instruction: Strategies to Help Students Make Abstract Ideas Concrete and Accessible”, he says Storyboarding, or picture writing, is the origin of all written languages, used by ancient cultures before text evolved and as a natural bridge to text. Pre-Writing is defined as Pre-writing is the first stage of the writing process, typically followed by drafting, revision, editing and publishing.
