Love this PowerPoint, a big thank you to the original uploader. Please refer to the link for a more detailed explanation.
Summary.
Teams take turns to choose the numbered questions (30 in total, 3 kinds), more questions are revealed as the game progresses.
All teams answer the questions on whiteboards.
Correct answers get points and sometimes the best or longest answers will get a bonus (see original upload for details).
Please edit slide 1 (your name) and slide 9 (your school's name).
I recommend you read the original poster's description.
I kept some of the original questions even though it was meant for High School as they are multiple choice so easy to explain/understand.

Thanks for creating this! Do you think you can add what textbook your school uses so other know if it's relevant to them?
