Although it is possible to create mathcasts with software like Microsoft Word, specialized math software, or other tools that generate text or images most of us have found annotation software like Smart Notebook software, Blade NotateIt, or Microsoft OneNote to be extremely helpful.

Question banks with dynamic questions are a great resource for mathcasts.

Graphics Input devices

Although you can create mathcasts with only a mouse & keyboard for input there are several types of graphics input devices like graphics tablets, Tablet PCs, and electronic whiteboards which will help you create mathcasts much more easily than with a mouse alone.
