At the end of the class period, a great assessment for the day is to give the students an exit slip for them to quickly fill in and turn in. It isn't an extensive test. It is simply a quick assessment that will let you see if your students understood the general idea of the class period.
It is formatted so you can easily print as many as you need and cut them into fours. Each slip will have a box around it, so it is neat in design.
I could not stand it when teachers handed me things to fill out that were obviously not thought out. Like they were just asking me to fill out time-fillers. As a teacher, I will not do that. If I cannot give them something that is easy on the eyes, they I will not give them something. It's a respect thing. =)
