I did a lesson with my low-level high school students talking about commercials and advertisements.  The main focus was on travel commercials and where they would like to visit in the future.  I had used some discussion questions and put it on PowerPoint with links to commercials in it from a variety of countries.  I tried to have links to places I knew before hand the students had wanted to visit from the introduction lesson.  We ended by picking a favorite product and looking at commercials on that product from different countries comparing how they were similar and different.  Some classes ended differently but these were the types we ended with coke, McDonalds, milk, ice cream and funny commercials.  The ending and conclusions isn�t on the PowerPoint.
