I always have my students keep their own 3-ring binder for Spanish class. It helps to keep us all organized. At the end of the year students have a great resource to keep for years to come! (We will usually clean out some sections mid- and end-of-year, like "Homework.")
I developed this idea after my first couple of years of teaching after a student came to me and said, "I just don't know how to organize myself for this class." This index gives you a good idea of how I organized our papers and handouts for 20 years! It is editable for your needs in the classroom.
