I've created a series of video screencast tutorials for Scratch. Scratch is a block-based programming environment from MIT. It is a programming education toy that is made for kids between the ages of 8 and 16. The screencasts can be found at:
Scratch itself is hosted at http://scratch.mit.edu
I highly recommend Scratch as a teaching tool for younger kids who may not be ready for Python programming or are frustrated by their slow typing. Scratch is a drag-and-drop environment with code "blocks" that snap together.
