Depending on their use, it may be important...https://education.ti.com/en/activity/detail/numb3rs--season-2--better-or-worse--creating-random-numbers
Experimentally Calculating Pi
Because the diameter of a circle is related to the circumference of a circle, we can find this constant relationship by measuring several lids and fitting a regression line to the data. The slope of this line is pi. This is a great activity to allow students to discover that Pi is the relations...https://education.ti.com/en/activity/detail/experimentally-calculating-pi
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

Use the U.S. Constitution, Scrabble, and your graphing calculator to examine a number of statistical concepts with your Algebra 1 students.https://education.ti.com/en/activity/detail/scrabble-math
The Spread of Disease
In this activity, students simulate the spread of a disease in a population. They use the Probability Simulation application to learn that certain sums occur more often than others because of combinations of addends of those sums.https://education.ti.com/en/activity/detail/the-spread-of-disease
To Toss or To Simulate?
Students use the RandInt() command to simulate the tossing of a coin and the rolling of a die. They will collect data for several trials and use the information to investigate the Law of Large Numbers.https://education.ti.com/en/activity/detail/to-toss-or-to-simulate_1
NUMB3RS - Season 3 - "Democracy" - No Desk Left Behind
