DLT:
  • Use pen drawing to make the turtle draw
  • Create custom shapes using the turtle object
  • Graph using the turtle tool
  • Apply concepts from this lesson to set up a turtle screen, change the screen’s background color, and move the turtle object
  • Apply knowledge of the coordinate system to turtle graphics

Vocabulary:
  • Turtle Graphics: Turtle graphics uses a "turtle," which functions as the reference point on a Cartesian plane. It’s quite commonly to introduce kids to computer graphics using turtle graphics.
  • Turtle Screen: The turtle screen defines the graphics window where you will draw using the turtle object.
  • Turtle Object: The turtle object is the object or cursor that will do all of the drawing.
  • Coordinate System: The turtle screen coordinate system is similar to the standard Cartesian coordinate system, with the following important differences:
      • The point (0, 0) is found in the center of the turtle screen
      • x-values increase as you move from left to right (this is the same as the Cartesian coordinate system)
      • y-values increase as you move from bottom to top

Activity:
  • Tynker Python: Using the Turtle Tool - Congratulations! You’ve made it to the first lesson of Part II in the Python 101 programming course. In Part II, students will transition from puzzle-based learning to creating open-ended creative projects using the turtle tool. They’ll start with the absolute basics, like changing the background color and moving the turtle. However, very quickly, they’ll create more complex and interesting projects. Let’s get started! Due by the end of class .
