Welcome to Mr. Gross’s WonderfulWorld of TRIVIA!!!!

WARM UP:- Get your team names written down and try your best to do the WORKSHEET ON YOUR DESK. Work in table groups to help each other.

How it works….

• Each table group comes up with a team name• When Mr. Gross puts a question on the board, each

team must write their answer on the whiteboard at their table

• The “WRITER” will change for each question• You will have exactly 1 minute to answer each

question – everyone holds up boards at same time• Once you hold your board up, you cannot put it

down for any reason (or you will not get a point)

NEVER, NEVER, NEVER…..

• TALK WHEN YOU ARE HOLDING UP YOUR BOARDS – YOUR TEAM WILL NOT GET A POINT IF YOU ARE TALKING

IF…..

• Your team wins, I will bring in treats for your team on Thursday while you are taking the test.

• There is a tie, or if the whole class ties, I will bring in treats for the whole class on Wednesday during the test…….what a great way to spend the middle of the week!
