Like many of us, I require that students keep a notebook of all their work relating to the class. Many of them at this age are just getting used to the idea of 'staying organized', so I help them by posting a table of contents on the wall. Whenever we do something in class, I add it to the list (or have a student add it), calling to the class' attention. The benefit goes far beyond having neat, organized notebooks. When I'm handing things out, the students are busy getting out their notebooks to add to their list. When a student is absent, they immediately know what they've missed so they can ask about it. And, when checking the notebooks, I can easily check off what the student has or doesn't have.
