I give this 11 question questionnaire to my high school students on the first day. Since I have juniors and seniors I spend a few minutes explaining how getting to know them is a top priority for me.
I give them this activity but tell them to keep it to 6 words or less. The words can be separate or make a sentence. Once they've completed them I collect them and I share them out loud. Students try to guess whose activity sheet I am reading. It usually generates a lot of laughs and helps them get to know each other. The fun part about it, is that I tell them NOT to write their names. I try to guess whose is it as well. If you use this activity, you can alter or change it to suit your needs.
Depending on the time I fill one out too and throw it into the mix. Students usually don't expect the teachers responses to be thrown in there too.
