They will then plot the x and y-values using a scatter plot to see the shape of the parabola. On top of this scatter...https://education.ti.com/en/activity/detail/introduction-to-quadratic-equations
Ratios of Similar Triangles
Students explore two ways of comparing side lengths of similar triangles. They will calculate ratios and change the triangles to see how the ratio changes.https://education.ti.com/en/activity/detail/ratios-of-similar-triangles
Dynagraphs
This lesson involves using a dynagraph to explore the relationship between the input and the output of a given function.https://education.ti.com/en/activity/detail/dynagraphs
Linear Transformations
This lesson involves linear transformations from R2 to R2 represented by matrices. Note: R2 = R x R represents the set of all pairs of real numbers.https://education.ti.com/en/activity/detail/linear-transformations
Rational Functions
Students investigate the graphs of functions of the form y = 1/(x - a). They will discover that the graph of such a function has a vertical asymptote at x = a, and a horizontal asymptote at y = 0. They will investigate the graphic and numeric consequences of such asymptotic behavior by observing ...https://education.ti.com/en/activity/detail/rational-functions_2
Spring Training
Students will explore parametric equations by finding the horizontal and vertical distances traveled by a projectile.https://education.ti.com/en/activity/detail/spring-training
Limacon Curve
In this activity, students will observe different graphs of polar limaçon curves. Students will discover four different types of limaçon curves and their relationship to the ratio of a to b.https://education.ti.com/en/activity/detail/limacon-curve
What Is My Rule?
This activity encourages students to gain experience with the language of the Cartesian coordinate system. Each of the problems shows two points, z and w. Point z can be dragged, and point w moves in response. In describing the rule that governs the location of point w, students will most likely ...https://education.ti.com/en/activity/detail/what-is-my-rule
Slope, Midpoint and Distance
The student will interact with a line segment and will report various conditions on a handout. Positive, negative slope, distance, and midpoints will dynamically calculate as the student drags either endpoint around.https://education.ti.com/en/activity/detail/slope-midpoint-and-distance

Sequence Investigation
In this activity, students will use a calculator page to create an arithmetic sequence. Through this they will learn some of the vocabulary of sequences. Then students will then use slider functionality to explore the effect of each variable in the formula of the nth term of an arithmetic sequenc...https://education.ti.com/en/activity/detail/sequence-investigation_1
Once and For All...Absolutely
The activity is designed to be a lesson in solving absolute value inequalities. The intent is to distinguish the kinds of solutions that absolute value inequalities have and the forms of stating the solutions. More importantly the activity considers two methods of solutions: a graphing method and...https://education.ti.com/en/activity/detail/once-and-for-all---absolutely
Pythagorean Proofs
In this activity, students will explore proofs of the Pythagorean Theorem. Students will explore the proof of the Pythagorean Theorem using area of squares, area of triangles and trapezoids, and by dissection. Students will then be asked to apply what they have learned about the Pythagorean Theorem.https://education.ti.com/en/activity/detail/pythagorean-proofs_1
