With each chapter, you gain more knowledge about Scratch. You learn about more blocks of code and how to use them. This chapter focuses on the blocks in the Pen category. With these, you can write scripts that draw designs on the stage automatically. The blocks of code in this category are green and they perform different actions like drawing, changing the pen size and color, creating a copy of the sprite, and removing all marks previously created by the pen or stamp on the stage. After investigating how the various Pen blocks of code work, you’ll practice using them in some examples scripts.
