This start of school survey that I call the "Getting to Know You Questionnaire" is a great first day or first week of school activity. It will only take 5 to 10 minutes, but you will come away with a wealth of information and insights into your students. I've easily used this with all middle school grades, and it would work the same with high school as well.
I tend to use this as a warm up type activity at the beginning of the hour on the first day of school. Simply print, copy enough for all your students, distribute, allow them to complete, and collect!
