The Improvisation Game - 45 Second Speeches with 98 Fun Mini-speech Topics

A great speaking exercise to get both your shy and bold students enthusiastic about speaking English. The goal of the game is to make a 45 second improvised speech on a random topic (98 topics are provided). You get points for making a successful speech. 
Very little preparation time: requires a bit of cutting with scissors, but not much else. Just put the instructions in a PowerPoint to make explaining the game easier. Adjust the timings of the speeches to the level of the students. I got some ideas from this site: I truly hope this will help you with giving your English speaking lessons.
