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
NUMB3RS - Season 2 - "Soft Target" - Is This Seat Taken?
In "Soft Target," Alan is considering how to arrange people in seats at a wedding. Charlie points out that although there are many possibilities for seating arrangements, you reduce those possibilities if you decide who needs to sit next to whom.https://education.ti.com/en/activity/detail/numb3rs--season-2--soft-target--is-this-seat-taken
Changing Before My Eyes
In this activity, students will discover how pictures formed by graphing ordered pairs can be stretched (and shrunk) by multiplying (and dividing) the coordinates.https://education.ti.com/en/activity/detail/changing-before-my-eyes
NUMB3RS - Season 3 - "Traffic" - Birthday Surprise
Students will study the birthday problem and other similar applications.https://education.ti.com/en/activity/detail/numb3rs--season-3--traffic--birthday-surprise
NUMB3RS - Season 2 -"Hot Shot" - A Stab in the Dark
In "Hot Shot," two victims of a possible serial criminal are found. Charlie uses kernel density estimation as a method for predicting a change in behavior to indicate a connection between the victims and the criminal.https://education.ti.com/en/activity/detail/numb3rs--season-2-hot-shot--a-stab-in-the-dark
Scatter plots and Linear Regression
This activity is designed to introduce students to using the STAT function of the calculator to determine the equation for a line of best fit.https://education.ti.com/en/activity/detail/scatter-plots-and-linear-regression
Matrix Transformation of Triangles
The symmetry of a trangle on the coordinate plane is discovered through the 2X2 matrix transformations.https://education.ti.com/en/activity/detail/matrix-transformation-of-triangles
Parabolic Applications
Students will analyze a parabola graphed from word problems. Students will use the calculator to find the roots and vertex of the graph to answer questions based on the word problems.https://education.ti.com/en/activity/detail/parabolic-applications
Linear Equations Given Two Points
Given two points, the students will submit linear equations that pass through the points, using the TI-Navigator™ system. The teacher can evaluate student answers as they are submitted.
