This is a fairly simple telco lesson, mainly aimed at older teenagers and young adults. Students form groups of 3 to 5, and create a mini company, then devise and sell mobile phone plans (=cell phone plans) to other students. I've done this lesson with 2 classes, pre-int/int, then later, advanced. The lesson took 2 hours for the lower class, 90 minutes for the higher. The students get some plans to start with, and add one of their own. They also create a special offer to go with their plan. It's probably my most successful and interesting lesson, and led to lots of English, with very little pushing. It's "true" level is pre-int to advanced, but it could be dumbed down for adult elementary students (if any actually exist ;0)
