Have students practice chatting about a variety of topics either daily or weekly. Must be intermediate/advanced with a good amount of vocabulary. First have students brainstorm the necessary vocabulary either by memory or looking up words in the dictionary that they may need; this is a great way to get them used to using dictionaries rather than asking the teacher! Suggested idea: have students start a "vocabulary journal" so that they are keeping it all in one place if you decide to do this often. As you circle back to topics and have them talk with new people a second or third time, they will already have the vocabulary!
