(Sorry about the French, my computer was not saving it when I changed the title. It is supposed to be Which Suitcase? in English) Students get into teams of 3-4. Decide which team will go first. The team going first picks a suitcase. Each suitcase has a question in it. When a team picks a suitcase they have 1 minute to solve the problem. If they do not answer in 1 minute, the next team gets 30 sec. to steal the suitcase and each team after gets 30 sec. until a team gets the correct answer. The team that gets the answer correct keeps the money that is in the suitcase. The level of difficulty does not determine how much money is in a suitcase! Suitcases range from $1 to over $2000! Could be used for a final year review or maybe a pre-assessment at the beginning for the year to see what students know.
