They would go into the center of the room, and the question is, "how would _you_ move if you were to make a square trail?" They would do that, and, doing so, try to remember what kind of moves and turns they did. This is enormously easier that to try this thing on paper.<br /><br />Another interesting metasolution from Papert is the rule that a full turn is 360 degrees. Children who can do multiplication/division can calculate all kinds of things on this, such as the turning angle you need in the tips of a pentagram. The turtle goes two full rounds and turns five times, so the right angle is 2*360/5 = 144.atehwahttps://www.blogger.com/profile/11825820178694736641noreply@blogger.com
