Start simply with Forward [number of steps], Right 90, Left 90. You can draw a surprising variety of patterns with just these.

Gradually add commands, such as Back, Pen Up and Pen Down, SetColor (change ribbon), Repeat (have one child keep the count), Right/Left 45/60/120/135, Store Value in Box (have a student keep track of that value), and whatever else the children show readiness for.

Children can start by giving any sequence of directions they like, but after a while, they should be challenged to make particular patterns and to generalize. Can you make a polygon of any number of sides? How do you express the angles? Can you make star shapes? Can you invent directions? How can a child walk in an accurate circle? (Hint: string) How about a quarter circle?

Children can start by giving any sequence of directions they like, but after a while, they should be challenged to make particular patterns and to generalize. The patterns above and many more like them are provided as challenges in the [http://activities.sugarlabs.org/en-US/sugar/addon/4331 Spirolaterals activity], which then leads to the Turtle Machine activity. Peter Hewitt designed them both as precursors to Turtle Art. Can you make a polygon of any number of sides? How do you express the angles? Can you make star shapes? Can you invent directions? How can a child walk in an accurate circle? (Hint: string) How about a quarter circle?

At this point, we are in a research project, specifically Seymour Papert's project from the 1960s, which asks whether we can make it as natural for children to learn math as language. You Be the Turtle has not been done enough to know what preschool children can understand immediately, what they need hints for, what they have to be shown, and how far they can go. We do not know what levels of art or programming or math they can achieve in Turtle Art or otherwise. We do know that it is more than they have been supported in doing so far.
