Well, then, let's add a third repeat loop. There are also some variables, for color and size, and the student should at some point understand how variables are set, to start off, and changed as the program runs. But that is not necessary at first. Appreciating the result at the pre-school level is enough to begin with. Making small changes and seeing their effects is also good, as experience shows third-graders can do. What if you replace the subtraction in setting the colors with something else? Understanding all of the pieces of the program can come later, and understanding how Turtle Art makes each piece work, later still.

Well, then, let's add a third repeat loop, but this time separate the inner loops into separate actions. There are also some variables, for color and size, and the student should at some point understand how variables are set, to start off, and changed as the program runs. But that is not necessary at first. Appreciating the result at the pre-school level is enough to begin with. Making small changes and seeing their effects is also good, as experience shows third-graders can do. What if you replace the subtraction in setting the colors with something else, or just change the starting number? Understanding all of the pieces of the program can come later, and understanding how Turtle Art makes each piece work, later still.

Two familiar parts with different numbers, and a new loop.

Suddenly we have moved from basic geometry and programming to the beginnings of art. Students who understands this much can read many of the other examples provided with Turtle Art, and begin to understand how the math, programming, and art fit together. Then they get to create their own, and show them to everybody.
