In this step, you’ll use code to ‘drive’ the turtle around the screen, and work through a few built-in exercises to familiarise yourself with Turtle. You’ll then make your own drawing using code.
As you’ll see when you learn to control Turtle, computer graphics code inevitably ends up involving a little maths. Don’t worry if you aren’t confident with maths; you’ll be given assistance with the maths required.
Turtle has a long history in computing and education. It was a key part of LOGO, a programming language invented in the 1960s at the Massachusetts Institute of Technology (MIT) as a tool for teaching and learning. Turtles were originally physical robots that drew on paper on the floor. Later, they moved onto the computer screen.
