This is a template that can be used as an exit ticket for students of any grade and age group. I have an "@_________" line that is for students to either write their real names or they can come up with a nickname. The other line is for the "fecha" or date. I used this for students to answer a question at the end of the day. I would tell them to "Twitéame" and post a question on the board. Then, students would get a "tweet" paper and turn it in before the class period ended. This was a good formative assessment to see how students were doing with any specific material we covered in that class.
I also made a bulletin board where I used an over-the-door shoe hanger for each student to have a slot to put their tweet at the end of the class.
