Press the G key to begin. The challenge is to create three new scripts, each based on the "drawPolygonInQuadrant1" script. The first script that you create should reflect the polygon in Quadrant I over the x axis into Quadrant II. The second script that you create should reflect the polygon in Quadrant II over the y axis into Quadrant III. Finally, the last script that you create should reflect the polygon in Quadrant III into Quadrant IV.
The xy-coordinate grid backdrop that I used for the title screen is supplied with Scratch. I originally created programs like these back in the 80's and 90's using Logo, LogoWriter, and MicroWorlds. It is very exciting that their decendent, Scratch, is free and online! Thanks to everyone who worked to create all these wonderful programming languages that make computer programming accessible to kids.
