Each morning my students answer a yes/no question of the day by moving their numbered magnet to the "yes" or "no" side of the board. This gives me a quick glance at who is absent and insight on students. The questions can come from relevant subject material or just be fun. It is a valuable tool to learn about my students and it shows them that they have something in common with everyone.
I have included 40 generic questions (for those days that our coffee hasn't kicked in yet!).
