Give your students one or more statements to prove or disprove. The statements can tie in with the topic or the grammar point of the class. Examples: Nobody in this class likes winter. Everyone here can draw a Volkswagen Beetle car.
Students talk to as many other students as possible to prove/disprove the statements. Then they give feedback to the class: 'This statement is not true. There are at least 5 people in this class who like winter.
