NUMB3RS - Season 3 - "Traffic" - What is Random
In "Traffic", Charlie lectures about randomness, explaining that 'our brains misperceive evenness as random and wrongly assume that groupings are deliberate'. In mathematics, we expect to see some clustering, or an occasional appearance of a pattern, when examining truly random events. In this ac...https://education.ti.com/en/activity/detail/numb3rs--season-3--traffic--what-is-random

NUMB3RS - Season 2 - "Double Down" - That's So Random
In "Double Down," three college students attempt to get an edge in a casino card game by analyzing the mechanical randomization process used to shuffle the cards. As Charlie explains, the auto-shuffler relies on an algorithm to deal the cards in random order. The students are able to crack the al...https://education.ti.com/en/activity/detail/numb3rs--season-2--double-down--thats-so-random
Net Present Value and Internal Rate of Return
In this activity, students deal with cash flow and its present value, which is its worth in today's dollars. They will compare alternative investments by determining their Net Present Value and Internal Rate of Return. They will also determine, when called for, whether it is more profitable to le...https://education.ti.com/en/activity/detail/net-present-value-and-internal-rate-of-return
Returns on a Share of Stock
In this activity, students will determine the internal rate of return of the cashflows associated with the stock purchase, dividends, and sale. They will carry out explorations by varying the selling price of the stock and examining the impact on the rate of return.https://education.ti.com/en/activity/detail/returns-on-a-share-of-stock
y=ax Activity
This activity, inspired by a similar activity in a Texas Instrument guidebook, has served to be very useful in helping students develop concepts of slope and y-intercept.https://education.ti.com/en/activity/detail/yax-activity

Application of Slopes
Students will apply the concept of slope to a real-world problem about building a staircase. They will use the slope ratio, vertical change over horizontal change, to find the slope of staircase. Then, students will recognize how a positive or negative slope applies in a real-world situation.https://education.ti.com/en/activity/detail/application-of-slopes
