What is Scratch?
Scratch is a development of the Lifelong Kindergarten Group at MIT Media Lab with the financial assistance of Microsoft, National Science Foundation, Intel Foundation, Google, MacArthur Foundation, Iomega and the research consortia of MIT Media Lab. It lets you create, program and share your projects of interactive music, games, art and stories. It enables its community of creators especially the young ones to learn mathematical concepts and computations while developing systematic reasoning, creative thinking and collaborative working. Its features include Research that contains presentations and documents about Scratch, News that contain Scratch stories in the media, Donate for Scratch project support, and Educators for information about those who teach using Scratch.
The steps to get started with using Scratch are: 1> Start Moving:You drag a ?move? block [left on the screen] into the Scripts space on the right.

Click any block to run your stack. A ?stop? button on top your screen allows you to stop. 5> Green Flag: Snap a ?green flag? block on top of your forever block. The ?green flag? will start your scrip every time you click it. To stop, click the ?stop? button. 6> Change Color: Drag ?change effect? block to your screen [below your stack]. Choose the color you want from its pull-down menu. Click to see the effect. 7> Key Press: Snap a ?key press? block to your screen. Choose a key from the menu. Press the command key to see the effect.
