Students identify whether points lie within a shaded region that is bounded by linear inequalities.https://education.ti.com/en/activity/detail/testing-for-truth
The Dirty Dawg Salon
In this activity, students will work through a scenario of a business venture involving washing dogs. They will translate fixed and variable costs to a cost function and make a decision about how much to charge to wash per dog. When the break-even point is found, students must interpret it to ans...https://education.ti.com/en/activity/detail/the-dirty-dawg-salon
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
Application of Slopes
Students will apply the concept of slope to a real-world problem about building a staircase. They will use the slope ratio, vertical change over horizontal change, to find the slope of staircase. Then, students will recognize how a positive or negative slope applies in a real-world situation.https://education.ti.com/en/activity/detail/application-of-slopes
Applications of Parabolas
In this activity, students will look for both number patterns and visual shapes that go along with quadratic relationships. Two applications are introduced after some basic patterns in the first two problems.https://education.ti.com/en/activity/detail/applications-of-parabolas_1
Common Denominator
In this activity, students will use an interactive model that multiplies the fraction by "1" to help determine the common denominator. Then they will use what they have learned to add and subtract fractions without the same denominators.https://education.ti.com/en/activity/detail/common-denominator_1
Beat the System
This can be used as an introduction to Systems of Equations. Students can work in groups or alone. They are shown graphs of the three different types of systems of equations and then asked to write equations of lines to create another set of systems.https://education.ti.com/en/activity/detail/beat-the-system
Triangles and Slope - Is the Triangle Possible?
Students will construct triangles that match specific criteria. If it is possible to construct the triangle, the students have to construct the triangle and state the slope of each side. If the triangle is impossible to construct, the students must write a detailed explanation as to why it is im...https://education.ti.com/en/activity/detail/triangles-and-slope--is-the-triangle-possible
The "Great Pyramid" - Rate of Change
Students will explore different rates of change. Using the TI-Nspire students will be expected to make predictions based upon information that a Pharaoh has given. Students will explore points in a scatter plot of time and height on the building of a pyramid in ancient times. They will calcula...https://education.ti.com/en/activity/detail/the-great-pyramid--rate-of-change
Birthday Simulation
In this activity, the students will conduct a simulation to predict the probability that two people in a room of thirty will have the same birthday.https://education.ti.com/en/activity/detail/birthday-simulation

Here's Looking At Euclid
Students first use the familiar prime factorization method to calculate the GCD and LCM of two numbers. Second, they apply Euclid’s algorithm, an iterative process for finding the GCD, in conjunction with a formula for the LCM given the GCD. In order to use the algorithm, they must first grasp th...https://education.ti.com/en/activity/detail/heres-looking-at-euclid
Area of the Missing Square
In this activity, students will be introduced to an area model for representing a quadratic equation. Students will explore the relationship between the value of b and c, in y = x2 + bx + c, form of the quadratic equation. The relationship will be examined with integer and non-integer values in o...https://education.ti.com/en/activity/detail/area-of-the-missing-square_1
