I used this game for preposition classes. This gets the whole class excited. You have to be prepared that there will be shouts, laughter etc in the class while playing this game. You can declare a few rules in the beginning - like how one team should raise their hands to be given permission to tell the answer, how you'll select if there are more hands from one team, after getting negative marking which team gets the next chance etc.
For the first part of the game the teacher needs to divide the whole class into groups. You can decide the number of members for each group. You can name the group and these names will appear on the board. The groups will prepare preposition exercises and hand the list of sentences over to the teacher. You should tell how many sentences with blanks for preposition you are expecting. During preparation time the teacher needs to move around so that same kind of sentences don't get repeated.
After getting the 5 exercises (considering that you have 5 groups), the teacher will start the game. When the teacher utters the sentences loud, the group which prepared that particular exercise will keep mum, and the other 4 groups will get the chance to answer by raising their hands. For each correct answer the groups will get points and the teacher will write down the points in the columns for the groups. For wrong answer there will be - 1 (minus one) for the group.
At the end the points are counted and a winner is declared.
