You will be writing a 5 paragraph persuasive essay about an issue that you believe in. This could be something as simple as why lunch at school should be free or trying to get someone to like the same things that you do (a video game, sport, music, etc.) It could be as complex as persuading someone on a more global issue like the environment or a political position. You will need to have supporting details and arguements to support your position.
