I use this schedule in my classroom to avoid the dreaded, "Is it my iPad day?" or "How come I never get to use the iPad?"
I give each child their own day of the week but you may choose to change the days to letters or numbers if your school follows that type of schedule.
This is a Word Document and completely editable - just add your students' names. I recommend saving it as a PDF before printing.
I put this schedule in a clear plastic picture frame in our technology center.
