RULES Today we are playing Jeopardy to Review for our test tomorrow. Get in groups of 2-3. You must all sit together. Each person will get a Marker and a Board. You will get about 30 seconds-2 minutes to answer each question. The team who chose the question can get double the points if they get the question right and hit a bball shot. All other teams can get the normal points for answering the question correctly Only hold up your answer on your board when you are told. Have someone record your points on your board. The top 3 teams will get a prize.
