Exploring Slope, Including a Study of Parallel and Perpendicular Lines
This activity contains 4 problems. The first 2 allow the students to notice relationships of slopes and y-intercepts to the location of lines. The second 2 problems help the students find the relationships between the slopes of parallel and perpendicular lines.https://education.ti.com/en/activity/detail/activity-with-slope-including-a-study-of-parallel-and-perpendicular-lines
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 also simulate distance versus time graphs using meter sticks and hot...https://education.ti.com/en/activity/detail/slopes-with-starburst
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
Circle Product Theorems
Students use dynamic models to find patterns. These patterns are the Chord-Chord, Secant-Secant, and Secant-Tangent Theorems.https://education.ti.com/en/activity/detail/circle-product-theorems_1
Midsegments of Triangles
In this activity, students will explore the properties of the midsegment, a segment that connects the midpoints of two sides of a triangle. First, students will construct and investigate one midsegment and the relationship of the new small triangle to the original triangle. Then, all three midseg...https://education.ti.com/en/activity/detail/midsegments-of-triangles_1
Interior & Exterior Angles of a Triangle
In this activity, students will measure interior and exterior angles of a triangle and make conjectures about their relationships.https://education.ti.com/en/activity/detail/interior--exterior-angles-of-a-triangle
Points on a Perpendicular Bisector
Students will explore the relationship between a line segment and its perpendicular bisector. The concept of a point that is equidistant from two points is illustrated.https://education.ti.com/en/activity/detail/points-on-a-perpendicular-bisector
