The First Day-Icebreaker

My first day back in the classroom was a fun one. I started by introducing myself and then had the students stand up and with only minute they had to ask "Who are you" to as many classmates as they can. We then went around the room and the student with the most memory's of their classmates will get a soda from me tomorrow. It was an icebreaker and the students liked it.
We then did the regular stuff for a first day and tomorrow the real work begins. If you have any icebreakers that you use I would love to hear them.
