Students move a quadratic function in the coordinate plane to specific points to observe how the vertex form of the equation changes.https://education.ti.com/en/activity/detail/around-the-vertex-in-80-days_1
Arithmetic Sequences & Series
Students use formulas to find the differences of the consecutive terms, plot a scatter plot of each sequence, and determine that sequences with common differences (called arithmetic sequences) have scatter plots whose points form a straight line.https://education.ti.com/en/activity/detail/arithmetic-sequences--series_1
Ellipses with center at (h, k)
Students will put the equations of an ellipse with center at (h, k) in standard form. Identify the center, vertices, co-vertices, foci, length of diamter axis, and length of the minor diameter. They will graph the ellipses.https://education.ti.com/en/activity/detail/ellipses-with-center-at-h-k
Introducing Families of Functions
Students will be able to identify important characteristics of specific function families. This activity focuses on linear and quadratic functions, but can be easily adapted to work with any family.https://education.ti.com/en/activity/detail/introducing-families-of-functions
End Behavior of Polynomial Functions - 84
This lesson involves determining the similarities and differences among functions.https://education.ti.com/en/activity/detail/end-behavior-of-polynomial-functions_1

Students will construct figures that prove the Pythagorean Theorem in two different ways.https://education.ti.com/en/activity/detail/the-pythagorean-theorem
Constructing Similar Triangles
Students investigate three different methods of constructing similar triangles.https://education.ti.com/en/activity/detail/constructing-similar-triangles_1
Operations of Signed Numbers( focus on vocabulary)
This activity will explore operations on integers with a focus on different vocabulary used to describe changes in signs and changes in operations.https://education.ti.com/en/activity/detail/operations-of-signed-numbers-focus-on-vocabulary
Hypothesis Testing: Means
Students test a claim about a mean with a large sample size at the five-percent significance level. The test statistic is found and compared to the critical value.https://education.ti.com/en/activity/detail/hypothesis-testing-means
Similar Figures Discovery Activity
Students will use Cabri Jr. to discover two properties of similar triangles: corresponding angles are congruent and corresponding sides are proportional.https://education.ti.com/en/activity/detail/similar-figures-discovery-activity
Law of Large Numbers: Adding It Up
In this activity, students examine the relationship between relative frequency and theoretical probability to understand the Law of Large Numbers. They will explore the concept of independent events. They will also discern the difference between relative and cumulative frequencies.https://education.ti.com/en/activity/detail/law-of-large-numbers-adding-it-up
On Your Mark, Get Set, React
This session will demonstrate a novel approach to reaction time experiments done in junior science and mathematics courses.

The three factors are weighted differently in different parts of the race. They compare the experimental and...https://education.ti.com/en/activity/detail/off-to-the-races
NUMB3RS - Season 3 - "Waste Not" - Sharpshooter
It is believed that an unusually high occurrence of cancer in a small area may represent a "cancer cluster." Because this is rare, it is more likely to be a case of "Texas Sharpshooting." For example, suppose a person randomly shoots a gun several times at the side of a barn and draws a circle ar...https://education.ti.com/en/activity/detail/numb3rs--season-3--waste-not--sharpshooter
