I teach English as a second language. Most of my students are very serious though they are taking the classes more for personal improvement than for any driving need. I want them to relax and enjoy using English but I can't seem to get them to understand there are no Language Police.

I am looking for ideas to make English fun. One of the exercises I am using currently is a sentence format where we make up silly sentences, e.g., I am washing my lunch.

I am looking for ideas to add more humor and enjoyment to these classes.
