Students stretch and translate the parabola given by y = x2 and determine the effects on the equation.https://education.ti.com/en/activity/detail/stretching-the-quads
Hot Air Balloon
Using a dynamic manipulative, students will have a visual for adding and subtracting integers.https://education.ti.com/en/activity/detail/hot-air-balloon_1
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
Radical Transformations
Students will use the Transformational Graphing application to examine how the square root function is transformed on the coordinate plane.https://education.ti.com/en/activity/detail/radical-transformations

This lesson involves determining the similarities and differences among functions.https://education.ti.com/en/activity/detail/end-behavior-of-polynomial-functions_1
Circle Product Theorems
Students will use dynamic models to find patterns. These patterns are the Chord-Chord, Secant-Secant, and Secant-Tangent Theorems.https://education.ti.com/en/activity/detail/circle-product-theorems
Constructing Similar Triangles
Students investigate three different methods of constructing similar triangles.https://education.ti.com/en/activity/detail/constructing-similar-triangles_1
Surface Area of a Cylinder
Students define right and oblique three dimensional figures and calculate the volume for prisms, pyramids, cylinders, and cones.https://education.ti.com/en/activity/detail/surface-area-of-a-cylinder
Midsegments of Triangles
Students explore the properties of the midsegment, a segment that connects the midpoints of two sides of a triangle.https://education.ti.com/en/activity/detail/midsegments-of-triangles
Midpoints in the Coordinate Plane
Beginning with horizontal or vertical segments, students show the coordinates of the endpoints and make a conjecture about the coordinates of the midpoint.https://education.ti.com/en/activity/detail/midpoints-in-the-coordinate-plane_1
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

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
NUMB3RS - Season 3 - "Waste Not" - Different or Not?
