This is a great way to get to know the kids in your class and it is different then the usual "What's your favorite book? What's your favorite food?" worksheet. You can use this PowerPoint as an individual activity where students write out their train of thought on a piece of paper, a partner activity, a group activity, or for the whole class!
In my experience, the kids in my class ALWAYS want to tell what they have chosen and why, so this would be perfect for a first week activity! Plus, you can easily incorporate writing. If you teach ESL, this is an excellent way to get in some listening and speaking!
