Texas Instruments: Numb3 Rs: Thinking Backward
Based off of the hit television show NUMB3RS, this lesson gets students to work backward, or to find the inverse, of given problems. Two type of problems are presented: one is the graph of a parabola, and the other involves bank shots on...
Texas Instruments
Texas Instruments: Numb3 Rs: Creating Random Numbers
Based off of the hit television show NUMB3RS, this lesson introduces students to the notion of randomness and shows that some sequences are in fact just pseudo-random. Students then use a formula to create a series of pseudo-random...
Texas Instruments
Texas Instruments: Numb3 Rs: Tesseract
Based off of the hit television show NUMB3RS, this lesson introduces students to the idea of a fourth dimension, and has them deduce properties of the tesseract, a four-dimensional hypersolid. This is a good lesson to get geometry...
Texas Instruments
Texas Instruments: Numb3 Rs: It's All Connected
Based off of the hit television show NUMB3RS, this lesson uses students' knowledge of graph theory (networks) to introduce two measures of centrality (how connected a particular node is to the entire network), known as degree centrality...
Texas Instruments
Texas Instruments: Numb3 Rs: Sharpshooter
Based off of the hit television show NUMB3RS, this lesson forces students to consider the fallacy of computing probabilities AFTER a series of events have occurred. Known as Texas sharpshooting, student will find that finding the...
Texas Instruments
Texas Instruments: Numb3 Rs: Restaurant Rankings
Based off of the hit television show NUMB3RS, this lesson combines the topics of graph theory and matrix multiplication in order to see the path of customer referrals to different fictional restaurants. Students create a matrix based off...
Texas Instruments
Texas Instruments: Numb3 Rs: Navigating Networks
Based off of the hit television show NUMB3RS, this lesson has students analyze different networks to determine the maximum flow rate of each network. This is done in the context of power plants supplying the community with electricity....
Texas Instruments
Texas Instruments: Numb3 Rs: Meltdown
Based off of the hit television show NUMB3RS, this lesson has students explore the relationship between a circle's area and it's radius. This is framed in the context of a scene in where a pile of ice is melting into an increasingly...
Texas Instruments
Texas Instruments: Numb3 Rs: Clearing All Obstacles
Based off of the hit television show NUMB3RS, this lesson has students modeling a mock food fight using projectile motion. This lesson is very technology-intensive, and a CBR2 is used to measure the velocity of an object so that it's...
Texas Instruments
Texas Instruments: Numb3 Rs: Seeing in the Dark
Based off of the hit television show NUMB3RS, this lesson has students try to emulate a time vs. distance graph on their graphing calculator using the CBR2. Next, the CBR2 is "swept" across an area in which three students are standing to...
Texas Instruments
Texas Instruments: Numb3 Rs: Up to Speed
Based off of the hit television show NUMB3RS, this lesson builds upon the familiar d=rt formula for distance to include elements of acceleration as well. The lesson is framed in the context of traffic flow theory, but makes some very...
Texas Instruments
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,...
Texas Instruments
Texas Instruments: Numb3 Rs: The Leaf Drops
Based off of the hit television show NUMB3RS, this lesson has students simulate the sinking of a yacht in the ocean, which is analogous to dropping a piece of paper in air. Students drop the paper multiple times and then calculate the...
