SP.68.3a- Determine the probability of an event occurring as likely or unlikely.
SP.68.3b-Deteremine the probability of an event occurring as likely, unlikely, certain or
impossible.
SP.68.3c- Understand a probability of 0 as impossible, probability of 1 as certain, probability
near 0 as unlikely and near 1 as likely, and near ½ as equally likely.
SP.IC.912.1c-Determine the likelihood (likely or unlikely) of an outcome from a data-generating
device.
SP.IC.912.1b-Determine the likelihood (likely, impossible, unlikely, certain) of outcomes from a
data-generating device.
SP.IC.912.2c-Understand a probability near 0 as unlikely and near 1 as likely using a number line.
SP.IC.912.2b-Understand a probability near 0 as unlikely and near 1 as likely
SP.IC.912.2a- Understand a probability of 0 as impossible, probability of 1 as certain, probability
near 0 as unlikely and near 1 as likely, and near ½ as equally likely.
Learning OutcomesStudents will develop and understanding of the math terms likely, unlikely, certain, possible.
Students will determine the probability of specific events
Students will determine if the probability of winning a new car is likely or unlikely
Background Knowledge- Students have been learning the meaning of the terms likely, unlikely, certain
and impossible. Now that students are getting familiar with the terms, they will begin applying them to
math. Previously they have been applied to real-world examples that students were already familiar
with.
Procedure: Classroom staff will model the game “Three Strikes” from the Price is Right.
The lesson will begin with a video clip of the Price is Right in which the contestant has a chance to win a
new car playing the game, “Three Strikes.” The video will be stopped before the end of the game to
keep students interested in the lesson and eager to find out if the contestant wins the new car.
After watching how the game is played on TV, classroom staff will demonstrate the game. Five numbers
and one strike will be placed in a bag. Students will determine if it is likely or unlikely that the contestant
picks a number as well as the likelihood of picking a strike. Higher level students will then work together
to determine the actual probability that the contestant picks a number from the bag. The contestant
(classroom para) will pick one token out of the bag. Assuming it is a number, the students will
determine the probability that the contestant correctly picks where that number is in the price of the
car. Students will then determine if this is likely or unlikely to happen. If a strike is drawn, it will be
placed back into the bag. If a number is not placed in the correct place for the price of the car, it will be
placed back in the bag.
As the game progresses, students will determine whether it is unlikely or likely that a contestant will win
a new car on a game show.
This procedure will continue until either the contestant wins the car or loses the game.
