Find the Equation of the Line
Teachers and/or students will look at given information (two points, a point and a slope, a point and a parallel line, and a point and a perpendicular line) and have to find the linear function that works. As the activity is occuring on the calculator, the students have a worksheet to record the...https://education.ti.com/en/activity/detail/find-the-equation-of-the-line
Rectangles and Parabolas
Students will tackle a traditional problem from the Algebra I curriculum geometrically, numerically, graphically, and algebraically: Sixty feet of fencing is purchased for the grounds crew to fence off a rectangular portion of property for a garden. The owner has made it perfectly clear that h...https://education.ti.com/en/activity/detail/rectangles-and-parabolas
Guess My Slope
Students will estimate the slope of six lines. Students will then return to each line and use the measurement capabilities of the TI-nspire to find the actual slope of each line. Students will find the absolute value of the differences between their estimates and the actual slopes in order to d...https://education.ti.com/en/activity/detail/guess-my-slope

Connecting Algebra 2 to Statistics
Once students learn how to solve exponential and logarithmic equations, the students can take data and decide if an appropriate model is exponential. This activity will require students to create scatterplots and to have the knowlegde of the relationship being linear or nonlinear. This activity...https://education.ti.com/en/activity/detail/connecting-algebra-2-to-statistics
Conditional Statements
In this activity, students construct examples of conditional statements such as parallel and perpendicular lines. After completing the conditional statement, they will write the converse, inverse, and contrapositive and determine if each is true.https://education.ti.com/en/activity/detail/conditional-statements
