In "Hardball," an amateur mathematician uncovers an equation that uses baseball statistics to identify which players are using performance enhancing substances. By analyzing player performance, he is able to determine when an athlete began using a performance enhancing substance. Students will us...https://education.ti.com/en/activity/detail/numb3rs--season-3--hardball--is-it-for-real
Explore Parallel and Perpendicular Lines
Students will use a graphing calculator to explore graphs of parallel and perpendicular lines. Students will find that parallel lines have the same slope and different y-intercepts and that the slopes of two perpendicular lines are opposite reciprocals of each other. This Technology Lab accompa...https://education.ti.com/en/activity/detail/explore-parallel-and-perpendicular-lines
Too Many Choices!
Students investigate the fundamental counting principle, permutations, and combinations.https://education.ti.com/en/activity/detail/too-many-choices
To Replace or Not to Replace? That Is The Question
In this activity, students explore situations that involve compound events with and without replacement. They use different ways to conceptualize theoretical probability.https://education.ti.com/en/activity/detail/to-replace-or-not-to-replace-that-is-the-question
To Toss or To Simulate?
Students use the RandInt() command to simulate the tossing of a coin and the rolling of a die. They will collect data for several trials and use the information to investigate the Law of Large Numbers.https://education.ti.com/en/activity/detail/to-toss-or-to-simulate_1
NUMB3RS - Season 3 - "Democracy" - No Desk Left Behind
In "Democracy", Charlie calculates the likelihood that five people who knew each other would have died by accident in a two-week period. He estimates that the odds of this are 700 million to 1. To estimate likelihood of an event, a simulation can be used. In this activity, students use a simulati...https://education.ti.com/en/activity/detail/numb3rs--season-3--democracy--no-desk-left-behind
NUMB3RS - Season 2 - "Toxin" - How Hard Can It Be?
In "Toxin," the FBI tracks a serial poisoner who uses contaminated drugs.
