My students are always losing handouts (homework sheets, school notices, skill pages). I always run off three extra copies of each handout and place them in an in-basket. I use the top of a gift box in a convenient spot. If my students can't find a handout at the end of the day, they check the box and don't bother me. I clean out the box about every two weeks. This is a life-saver since the end of the day is hectic enough without having to locate a missing paper.
