Lesson 2: Simple version of the popular 'Logo' turtle graphics project. Experiment to change angles and repeat turns to make different geometric shapes. When you press the play button, the turtle moves and draws on the screen. Can you make it draw more lines. Can it draw a square?
One more of my favorite lessons to introduce programming. Made a simple turtle to experiment with the vector graphics of Scratch 2.0. Comments in code give suggestions on how to use in class.
