PROGRAMMING CLASS

Logo ProgrammingFall 2011 Session 7Programming ClassTeacher: M. TaghizadehSobhan HighschoolPen Up, Pen DownSo far, all of our drawings have had two limitations.

First, they are entirely made up of lines (no solid shapes).

Second, all of the lines are connected.

In this lesson, we will overcome these limitations. We will learn how to move the turtle without drawing a line. We will also learn how to fill in the outline of a shape with a solid color.Teacher: M. Taghizadeh Sobhan HighschoolLogo ProgrammingPEN UPPen Up, Pen DownPUPEN DOWNPDTeacher: M.
