Area of a Triangle
The student will use three methods for finding the area of a triangle. They will find the area using the determinant of a matrix, two sides and the included angle (trig) and Heron's formula (three sides).https://education.ti.com/en/activity/detail/area-of-a-triangle
Application of Maximum-Minimum Problems
Students will use a graphing approach to find the minimum costs of running a new line from a power station to a point on an island. Students will begin with a scaled drawing and follow the prompts. They will also manually collect data and find a curve of best fit.https://education.ti.com/en/activity/detail/application-of-maximumminimum-problems
Law of Sines
Students will investigate all the cases in which the Law of Sines can be used to solve a triangle. An animation is provided in the lesson which will help students to gain a better understanding of the ambiguous case SSA.https://education.ti.com/en/activity/detail/law-of-sines_1
Verifying Trigonometric Identities
The student will look at the different tools needed to verify trigonometric identitites including reciprocals, cofunctions, quotient, and Pythagorean identities. Students will also be introduced to the "Hexagon".https://education.ti.com/en/activity/detail/verifying-trigonometric-identities
Law of Cosines
Students are introduced to the concept of the Law of Cosines. They will explore the concept graphically, numerically, and algebraically. They will discover the Law of Cosines at the conclusion of the activity using TI-Nspire CAS.https://education.ti.com/en/activity/detail/law-of-cosines
What's My Absolute Value
Students will discover what taking the absolute value of a domain will do and what taking the absolute value of a range will do.https://education.ti.com/en/activity/detail/whats-my-absolute-value
Graphs of Sine and Cosine
The goal of this activity is for students to see how the graphs of sine and cosine are generated and related to the unit circle. A point is animated around the unit circle as data points are captured to create a scatter plot.https://education.ti.com/en/activity/detail/graphs-of-sine-and-cosine
How Much Does Bubble Gum Stretch a Rubber Band?
Students will conduct an experiment where they determine how much various quantities of bubble gum affect the length of a rubber band.https://education.ti.com/en/activity/detail/how-much-does-bubble-gum-stretch-a-rubber-band
Hitting Homeruns
It is a study of the way a hit baseball moves through the air in the sense of using a quadratic function.https://education.ti.com/en/activity/detail/hitting-homeruns
Radical Transformations
Students will use sliders to examine how the square root function is transformed on the coordinate plane.https://education.ti.com/en/activity/detail/radical-transformations_1
Graphic Designing with Transformed Functions
Create an image using transformed functions with restricted domains.https://education.ti.com/en/activity/detail/graphic-designing-with-transformed-functions
Linear Inequalities
Linear programming is a technique used to solve problems that are encountered in business and industry. These problems usually involve maximizing or minimizing profit or expenses. The solution will consist of graphing the region that satisfies all the inequalities. The solution will produce a fea...https://education.ti.com/en/activity/detail/linear-inequalities
Exponential Growth and Decay
This activity is a few word problems that involve some formulas that use exponential growth and decay.https://education.ti.com/en/activity/detail/exponential-growth-and-decay
Constructing an Ellipse
Students will explore two different methods for constructing an ellipse. Students discover that the sum of the distances from a point on an ellipse to its foci is always constant. This fact is then used as the basis for an algebraic derivation of the general equation for an ellipse centered at th...https://education.ti.com/en/activity/detail/constructing-an-ellipse_1
Watch Your P' and Q's
Students use the Rational Zero Theorem to find all rational zeros of a polynomial.https://education.ti.com/en/activity/detail/watch-your-p-and-qs
Getting Ready for Quadratics
This activity is intended as a skill-building exercise to familiarize students with TI-Nspire skills they will need to work through a unit studying the properties of quadratic functions. The activity includes exercises on Creating a Scatter Plot, Finding a Curve of Best Fit, and Tracing a Function.https://education.ti.com/en/activity/detail/getting-ready-for-quadratics
Solving Exponential Equations
Numeric, graphical and algebraic solutions to an exponential equation.https://education.ti.com/en/activity/detail/solving-exponential-equations
Drawing Dynamic Vectors with NSpire
This is a "how to" file for drawing vectors with a split screen with NSpire.https://education.ti.com/en/activity/detail/drawing-dynamic-vectors-with-nspire
Cybersecurity 1: All Clear
Activity 1 introduces students to “cleartext” messaging. Students will send messages between two micro:bit radios on one of 83 radio channels using plaintext characters, referred to as cleartext. The “student hacker” will attempt to eavesdrop on the conversation by listeni...https://education.ti.com/en/activity/detail/cybersecurity-1
