Multiplicity of Zeros of Functions
In this activity for the TI-84 Plus CE Family, students will utilize graphs and equations of polynomial functions to determine the zeros of the functions and whether the functions cross the x-axis or is tangent to the x-axis at the zeros.https://education.ti.com/en/activity/detail/multiplicity-of-zeros-of-functions_1
ASA Triangle Congruence
1.Construct an triangle and select two angles and the contained side to copy to a second triangle. 2.Measure sides and angles to visualize congruence properties 3.Try to alter the properties of their construction by moving the vertices of the original trianglehttps://education.ti.com/en/activity/detail/asa-triangle-congruence
Translations in the Coordinate Plane
It is important for students to know what happens to the coordinates of points when they are translated in the coordinate plane. This activity enables students to use Cabri Jr. to develop this understanding.https://education.ti.com/en/activity/detail/translations-in-the-coordinate-plane
Is an equilateral triangle a special case of isosceles?
The definition of isosceles triangle can determine whether an equilateral triangle is a special case of an isosceles triangle. Using the Cabri Jr. application, students can get a feel for which definition makes the most sense. Along the way, they get experience with a perpendicular bisector, me...https://education.ti.com/en/activity/detail/is-an-equilateral-triangle-a-special-case-of-isosceles
Is a square a special case of rectangle?
The definition of square can determine whether it is a special case of a rectangle. Using the Cabri Jr. application, students can get a feel for why its definition makes sense. Along the way, they get experience with perpendiculars, parallels, measuring lengths, and an informal look at the inte...https://education.ti.com/en/activity/detail/is-a-square-a-special-case-of-rectangle
Inference for Correlation and Regression
In this activity, students test if a significant relationship exists between a bivariate data set, and then calculate the confidence and predictive intervals. They also improve the interval-prediction capabilities by automating the process.https://education.ti.com/en/activity/detail/inference-for-correlation-and-regression
Law of Large Numbers: Adding It Up

NUMB3RS - Season 3 - "Traffic" - What is Random
In "Traffic", Charlie lectures about randomness, explaining that 'our brains misperceive evenness as random and wrongly assume that groupings are deliberate'. In mathematics, we expect to see some clustering, or an occasional appearance of a pattern, when examining truly random events. In this ac...https://education.ti.com/en/activity/detail/numb3rs--season-3--traffic--what-is-random
