There are 30 cards featuring controversial statements on different topics. The point is to read a statement and not only make a verdict - agree or disagree - but also provide arguments and explain the reasoning behind your opinion. These statements include thought-provoking topics that stimulate critical thinking.
For group activities, we recommend splitting the class into two teams. Give both teams one controversial statement, with one team presenting arguments 'for' and the other team presenting arguments 'against' the statement.
