My forte is games for kindergarten classes, but 4 times a year my company has a company-wide training session and we play games there as icebreakers and team-building activities. Some of the ones that could probably be used in the classroom are those that require some mingling and interviews. You can assign everyone an animal and have everyone mingle and ask questions (what color are you? are you bigger than a ___? do you have a long nose? etc.). The only thing they can't ask is the direct question of "What animal are you?" Have a list of all the animals and the students can write down the name of the person next to the animal they were assigned. This is a good activity for working on descriptions.

Maybe if you could go more into detail about the level of the students and the number(s) of students in the class(es), you could get more applicable suggestions.
