In this activity, students will explore the properties of rotations and the relationships between the original and image figures.https://education.ti.com/en/activity/detail/rotations-in-the-plane
NUMB3RS - Season 2 - "Assassin" - The Escape Game
In "Assassin," Charlie is trying to figure out where a killer might strike given that he knows who the victim will be. By analyzing the movements of the would-be victim, Charlie models the decisions that the assassin will make. This is an example of behavioral game theory, where the motives of tw...https://education.ti.com/en/activity/detail/numb3rs--season-2--assassin--the-escape-game
Simple Constructions
In this skill activity, students will use the Constructions Tools Menu in Cabri™ Jr. to contruct a parallelogram. They will also construct an altitude, an angle bisector and a median of a triangle.https://education.ti.com/en/activity/detail/simple-constructions
NUMB3RS - Season 3 - "Finders Keepers" - The Leaf Drops
In "Finders Keepers," a world-class racing yacht sinks in the ocean. The NSA has the exact location where its homing beacon shut down and assumes that is where the ship sank. The NSA is stumped when they cannot find the yacht at this location because they assumed the boat sank directly to the bot...https://education.ti.com/en/activity/detail/numb3rs--season-3--finders-keepers--the-leaf-drops
Collecting Pens (Continued)
In this activity, students learn how to instruct the calculator to collect and organize the results from several trials of a simulation designed to find out how many boxes of cereals a customer would have to buy to collect all six color pens. Students enter a prewritten program, analyze the resul...https://education.ti.com/en/activity/detail/collecting-pens-continued
Collecting Pens
Students explore simulation strategies to solve real world problems involving probability and randomness. They use the Monte Carlo procedure to simulate the collecting of six different colored felt-tipped markers from boxes of Kellogg's cereals. They examine and analyze summary statistics and sta...https://education.ti.com/en/activity/detail/collecting-pens
Assessing Approximate Normality in AP Statistics
In this activity, students are sent 5 lists of data to study. The groups must use previously-discussed strategies for determining if each set could have reasonably come from a normal distribution.https://education.ti.com/en/activity/detail/assessing-approximate-normality-in-ap-statistics
Real Number Properties
This StudyCards™ set promotes understanding of commutative properties, associative properties and the distributive property. Use with Foundations for College Mathematics, ch. 1-1.https://education.ti.com/en/activity/detail/real-number-properties
Dilations in the Plane (Transformations)
In this activity, students will explore the properties of dilations and the relationships between the original and image figures.https://education.ti.com/en/activity/detail/dilations-in-the-plane-transformations
Discovering Pi
Students will measure the circumference and diameter of round objects. They will send in their measurements through TI-Navigator™ and discover the relationship between the circumference and diameter. Students will note why all points do not lie exactly on the line y=PIx. Then students will use ...https://education.ti.com/en/activity/detail/discovering-pi
