Texas Instruments: Numb3 Rs: We're Number 1!
Based off of the hit television show NUMB3RS, this lesson introduces students to the not-so-well known Benford's Law, which helps identify random number sets that may have been fabricated. Students learn about Benford's Law by exploring...
Texas Instruments
Texas Instruments: Numb3 Rs: Galton Board
Based off of the hit television show NUMB3RS, this lesson has students find the probability of chips falling into each bin of a Galton Board (also known as a quincunx or Plinko board), and then graphing these data to form a normal curve....
Texas Instruments
Texas Instruments: Numb3 Rs: Branch and Bound
Based off of the hit television show NUMB3RS, this lesson is best used as an extension to linear programming in which the solutions to the proposed problem must be integers. The Branch and Bound method operates on the optimized point,...
