We have a large dry erase board in our kitchen and below it are 2 strips of cork to hang schedule/papers on. There is a section for groceries and the kids know to write it on the board if something has run out. We've used it for reminders of upcoming due dates/calls to make/what we give up for Lent/etc. I used it for the grandparents too and keep a kids' schedule on the board if we're out of town. If task is completed - away it goes with the eraser.
