Guilty as charged!
Although, with all the other users on this site, I don't know why no one else jumped in with suggestions.
To be honest Observador, I don't use comic strips in class and I see that as a much more heads down activity and I like to see my students using English (i.e. speaking) actively.
With my adult classes, I also prepare a class on small talk...that very important social tool...especially in business relationships. This would be a perfect activity for your lawyers. If you are interested, PM me and I will send you the full lesson outline on small talk. However one of the highlights is a speaking activity where the students simulate that they are on a long train ride (I usually use the Madrid to Paris route).
Each student is given a stack of cards that have words printed on them. The object of the activity is that they must correctly use the word or phrase on each their cards in the context of a natural conversation. The person who first uses up all their cards is the winner. Of course you, as the teacher, must be the referee and decide if the use of the phrase was natural or not.
This activity works great for all levels of speakers because you can create different sets of cards to challenge the students’ levels. For example, for lower level conversations, perhaps you want to focus on the use of “short answers” (i.e. “yes, I do”, “no, I haven’t” etc..). For more conversational speakers you can add random phrases such as “I don’t like anchovies on my pizza” or “I love techno music”. And of course for advanced levels you can add in idiomatic expressions that they must use within the context of a natural conversation (with random strangers on a long train ride).
It’s a fun activity and my students really enjoy it. However, they must be reminded that the objective of the game is to be the first to use all of their cards in a natural conversation and not simply to run through all of their words sticking them in a conversation in a non-sensical way.
Anyway, do share with us how you use comic strips in your classes!
