I use 'Find Someone Who (Simple Present)' as a warm up or as an activity following a lesson on SIMPLE PRESENT with adult learners. The reason I specify 'adult learners' is that the questions mostly relate to adult situations. The activity consists of finding people in the class who answer the given characteristics (e.g. find someone who loves fruit / who cooks French meals). All the questions are built so students practice simple present (do-does). There are 20 questions divided on two pages, so each half of the class has one page. Not only does this activity help with SP questions, it creates a dynamic environment because students walk around the class and get to know each other. For questions with verb 'to be' see my other work sheet 'Find Someone Who (to be).
