It is a good game based on a TV Show to practise zero and first conditionals. Divide the class at least 3 groups. The groups choose a number in turns and for each number there is a question. In 30 seconds students try to find only one popular answer. If their answer is the least popular they get 1 point, for the most popular answer they get 10 points.
Students love this game. Choose a leader from each group and tell them to stand up if their groups have an answer. If a group making a noise, they miss a turn. It always works.
