20 Questions One person thinks of an object (person, place, or thing). Everyone takes turns asking yes/no questions until someone can guess correctly (or until 20 questions are asked). The difficult part is that you cannot ask "wh" questions! Example: PINEAPPLE. Does it talk? No. Does it make life easier?
I like this activity very much, if I have opportunity I will definitely try this one, I think it'll motivate students and set a positive atmosphere in the classroom.
Wow amazing warm up activity! if you don't have time to make beautiful name pads, then this activity is just what you need. This will help your students and you to learn each others names and at the same time to enrich with new vocabulary. Another alternative to this, is writing down names of fruits and vegetables on the board beforehand, in order to help your learner to feel comfortable while participating in this game/activity.
