One Key Logo

One Key Logo is a great first project for Scratch Programmers and lets you draw shapes on the screen using the keys F,B,L,R for Forwards, Backwards, Left and Right. This project introduces the Green and the Ket Press control object as well as basic movement and the pen. The aim is to create a simple drawing project and finally to draw a square and a triangle to show the project is complete.

A more sophisiticated example with a play button allows you to illustrate turtle graphics and use one key logo for constctivist learding of geomerty.
