I copy my plan book from one year to the next. I also create class websites for each individual class. I don't want to have to go to each individual card, and deselect everything from the student view when I copy the book. So, it's the start of the new year and instead of spending my time doing something else, I have to go through each card of each class for each day for the year, and deselect the items from showing on the class website until a later date.
