Where’s the Point?
This activity can be used to introduce students to the Cartesian plane. They should have some familiarity with how points are located in the plane using two coordinates, but the emphasis in this activity is solidifying students' understanding of just how that is done. As configured, the activity ...https://education.ti.com/en/activity/detail/wheres-the-point
Successive Differences
Students explore the relationships between the side length and perimeter of a square and the edge length and surface area of a cube by manipulating geometric models. They use the models to generate a dataset, calculate successive differences, and use them to determine which type of function best ...https://education.ti.com/en/activity/detail/successive-differences
Parametric Equations
We express most graphs as a single equation which involves two variables, x and y. By using parametric mode on the calculator you may use three variables to represent a curve. The third variable is t, time. (Topics - parametric functions)https://education.ti.com/en/activity/detail/parametric-equations
Inequality Graphing App
Students explore inequalities by entering inequalities using symbols, plot their graphs (including union and intersection shades), store (x, y) coordinate pairs as lists, enter inequalities with vertical lines in an X= editor, and trace points of interest (such as intersections) between functions.https://education.ti.com/en/activity/detail/inequality-graphing-app
Social Security Issues
In this activity, you will look at the relationship between the age at which you start drawing social security and the amount drawn. Both graphs and spreadsheets will be used.https://education.ti.com/en/activity/detail/social-security-issues
