You’ve mastered the basics of guiding the Logo turtle with commands like fd, rt, bk, and lt. You can draw shapes, lines, and simple patterns. But what if you could teach the turtle entirely new tricks? What if you could give it a memory to store information, or even let it make its own decisions about where to go?

You are now ready to move beyond typing single commands and unlock the true creative power of programming. In this guide, you will learn how to give your turtle three essential superpowers: giving it a memory with Variables, cloning its skills with reusable Procedures, and giving it a mind of its own with Decision-Making. These skills are the key to transforming simple command sequences into complex, elegant, and fascinating drawings. Let’s begin by exploring how to make our code more flexible, starting with memory.
