So, it’s your first class with a group of beginner 12-ish year-olds. You just leaf through the course book and teacher’s guide because all the class is about is the verb to be and adjectives. You know the drill: a couple pages filled with yes-no questions and perhaps a list of cities and countries that might require some work on pronunciation. Oh, and there may be a tic-tac-toe or perhaps a suggestion of musical chairs towards the end of the lesson. We’ve been there, we’ve done that. Right?...
