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
Similar Triangles and Proportions

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
What's Normal, Anyway?
Students explore normal distribution and several properties. First, simulate a binomial experiment and use a histogram of the data to examine the general shape of a normal curve. They graph a normal distribution given the mean and standard deviation. They see how the graph changes when just the m...https://education.ti.com/en/activity/detail/whats-normal-anyway_1
Means With Confidence
Students estimate the true mean of a population when the standard deviation is known by finding the sample mean, margin of error and confidence interval.https://education.ti.com/en/activity/detail/means-with-confidence
What Is Your Grade (Part 1)
In this activity, students will use the CellSheet Application and set up a spreadsheet. They will determine the mean of a set of values and find a minimum value to be added to a set of values to obtain a given mean.https://education.ti.com/en/activity/detail/what-is-your-grade-part-1
Testing Hypotheses (Means, Proportions, and Standard Deviations)
In this activity, students evaluate hypotheses.https://education.ti.com/en/activity/detail/testing-hypotheses-means-proportions-and-standard-deviations
