Moody Mathematics
3Rules A question starts with a player. If that
player answers correctly he/she keeps his/her
seat.
Moody Mathematics
4If the player misses, then the question goes to
the next player. If missed, it goes to the next
player...
Moody Mathematics
5and continues until someone gets it correct.
That student moves to the seat where the question
started...
Moody Mathematics
6and everyone who missed the question moves back
one seat.
Moody Mathematics
7The object of the game is to occupy and keep the
1 seat.
Moody Mathematics
8Questions with a limited number of possible
responses will not be offered indefinitely. A
substitute question will be posed.
Moody Mathematics
9It is important to listen to previous responses.
They will not be repeated for you.
Moody Mathematics
10Have paper and pencil, formula sheet, and
calculator ready.
Moody Mathematics
11The first person to receive a question will have
a maximum of 30 seconds to answer.
Moody Mathematics
12Every person after that has only 10 seconds to
reply. Be ready when called upon.
