Transcript of The rules One person (known as “1”) will be chosen to compete against the rest of the class...
1 vs 100Cells
(Part 2)
The rules• One person (known as “1”) will be chosen to
compete against the rest of the class (known as “100”)
• 10 points are added to the “bank” with every question the “1” gets correct.
The rules• When a question is asked, the “100” have 5-10
seconds to record their answer on a whiteboard. – When I say, “MARKERS UP” you must stop writing.
• At the start, all “100” are “up” (sitting on their desk or standing).– Those who get it correct remain “up”. – Those who get it wrong must sit back down.– Get TWO (2) in a row correct, and you are back
up!
The rules• “1” wins the bank points by getting
Five (5) questions in a row correct.– Those still “up” each get ½ of the bank points.
• If the “1” gets an answer wrong, all remaining “100” (those who are still “up”) get the points in the bank.– “1” gets ½ of the points in the bank.
• Then we pick a new “1” and start again!
The person with the most points at the end of class is the
