REAL LIFE, REAL WORLD Activity - Architecture
Architects and Interior Designers use scale drawings that represent the house or room they are designing. This activity uses Cabri Jr. Geometry software to create a scale drawing with dilations.https://education.ti.com/en/activity/detail/real-life-real-world-activity--architecture
Measure Up!
In this activity, students' create a plot showing the heights of some of their classmates. They determine the extreme values and the median for the height data and construct a box-and-whisker plot to summarize the height statistics.https://education.ti.com/en/activity/detail/measure-up
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
Does Your Euler Line "Wiggle"?
The students will construct an Euler line and demonstrate it is an Euler line by "wiggling" the triangle to guarantee the correct centers remain on the line.https://education.ti.com/en/activity/detail/does-your-euler-line-wiggle
