Lesson plan entry: “Hand out worksheet packets and have students staple before starting. They know what to do.”
Sounds simple enough! Four numbered sheets, eight total pages, printed front and back. What could go wrong?
Do you know how many possible combinations four pieces of paper can be arranged for stapling? I believe it’s something like 1024 possible variations (not counting upside down). Fortunately, I had only 32 to check and fix.
Math wizards welcome to provide the number of actual variations possible – upside down or not.
