  1. 2 computers (Windows or Macintosh)
  2. Kali software
  3. Printer (preferably color)


  1. In each group, students should work in pairs.
  2. Open the program 'Kali'.
  3. Go to OPTIONS and select BACKGROUND. There is a slider below the color wheel. Slide it all the way to the right. Select OK. This will make the background white, which will improve the printed product.
  4. Close the wallpaper palette and open the rosette palette.
  5. Select one of the symmetry groups in the rosette palette by single-clicking on it.
  6. To make your symmetrical design, single-click on the screen to start drawing, and double-click to stop.
  7. To erase, just select another symmetry group in the rosette palette.
  8. Selecting different colors will add variety to your drawing.
  9. When your drawing is complete, go to FILE and select PRINT. When the window appears, press return.


Each student should have made a printed symmetrical drawing.
The Scribe checks off the station on the recording sheet.


  1. Quit the program so that the computer will be ready for the next group of students.
  2. Place all drawings in the group folder.
