A specific method of instruction where one attempts to teach a task by teaching the last step first and working through a task analysis in reverse.

• EX:
  Putting together a new puzzle. The instructor would prompt the student to put in all of the pieces in the puzzles. They would fade the prompt on the last piece while continuing to prompt the student through the rest of the puzzle. Once the student puts the last piece in independently (no prompts), the instructor can begin to fade prompts on second to last piece.
