Projects

A new series of projects is being devised for release early 2008 the first of which is available now:

• Fish! - a simple game for novice scratch programmers with full notes.

These project link directly to the Scratch project file and the browser will try to open Scratch on your computer and load the relevant project. If you did not associate the Scratch application with files with an sb suffix or do not have Scratch installed then you may have problems with these links.

• Onekey is a simple project for younger children to control the sprite with simple turtle graphics commanfs including forward, back, right and left movements to create simple shapes on the stage.
• Iteration is an extension to OneKey containing two sprites and contunuous movement.
• Throw is an aid for young children to begin to understand angles by turning the sprite around to throw an object at a target and see the value of the angle, between zero and 360, displayed on the stage.
