Here is a powerpoint I made providing the students with the story of the film, "The Wizard of Oz". I found that it served to both give some background to the video for that lesson and make it more interesting to the students (some of which knew the story, but most of which had only heard the name 'Oz').
For me, this made doing the roleplay later in the period more fun, and it took up enough time that I could completely skip the bizarre 'World Tour' portion that was entirely in Korean.
