Preposition Game.

I would like to do a sort of Jeopardy style game.
The class would be divided into 4-5 teams. And there would be 3 catagories Time prepositions,Place prepositions and Direction preposition sition Each catagory would have 5 levels for points 100, 300, 500, 700, and 1000. With the role of a dice we decide which team picks first. The first team to write the answer and raise there hands get to answer. If they get it right they get to pick the next catagory and for how many points. However, if they get it wrong any other team can answer and the team that got it wrong you take away the amount of points the question was worth. The team at the end with the most points wins.
