This is a zip file containing 16 Turtle Graphics exercises.

I decided to make these having seen what is offer for download on the internet. I did not like what I saw for the following reasons:

  1. Many were so polychromic they would bust my bank account in terms of coloured ink.

  2. They tended to contain images of the completed code-block construction as well as the design, which seemed to miss the point.

What you get in my Zip file:

  1. 16 greyscale Turtle graphics challenge cards as individual PNG images.

  2. 3 greyscale PNG images containing the 16 challenge cards ready for printing (A4).

  3. 3 PDF documents containing the 16 challenge cards ready for printing (A4).

  4. A GIMP template file in case you want to mess around with things.

I suppose these are for beginner to intermediate level, although I am not entirely sure how one would go about calibrating them in anyway that could be said to be vaguely objective,


  1. These can be used with floor robots that are either proximally (built in keys) or remotely controlled.

  2. These can be used with any of the large number of turtle graphics programs that are available either commercially or free: I favour Turtle Art and/or Turtle Blocks which I am currently running on Xubuntu 14.04 32-bit machines.

I have printed out multiple sets and run them through my laminating machine.
