WEB TURTLE is a fun drawing program which uses what's called "Turtle Graphics" (the same thing the computer language "Logo" uses for graphics). The idea behind "Turtle Graphics" is that you have a turtle who's got a pen stuck to its tail. You give it commands (like "go forward", "turn left", etc.) and it draws shapes on the screen.

Web Turtle can be used to help teach simple computer programming as well as the basics of geometry! It's completely web-based and doesn't use Java, plug-ins or software downloads, so it should work on almost any type of computer that has a web browser!

If this is your first time, start by playing with an existing example drawing. Use the "Available Commands" / Help page to find out how Web Turtle works. Then try creating your own programs by starting a new drawing.

March 2012 - Documentation incorrectly said 0 degrees was up, when it is actually right; 90 degrees is up.
Also, added a new command, 'FORGET'. It is used to 'pop' (remove the most recent) 'REMEMBERed' location, without actually returning the turtle to that position (as 'GOBACK' does).

For example, commands like this would draw a square:

In English:

  1. Draw with a Black pen
  2. Do this Four Times:
    1. Move Forward 10 Paces, Drawing
    2. Turn Right 90 Degrees

What you tell Web Turtle:

  DRAW 10
  RIGHT 90
