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
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
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
The Open Box: An Exploration of Maximum Volume
The students will solve the problem of finding the maximum volume of a box cut from an 18 x 24 cm peice of paper in several ways. The student will actually cut out and form several different boxes. The student will fill the boxes with "starburst" candies and then use their TI-Nspires to analyze...https://education.ti.com/en/activity/detail/the-open-box-an-exploration-of-maximum-volume
Pythagorean Proofs
In this activity, students will explore proofs of the Pythagorean Theorem. Students will explore the proof of the Pythagorean Theorem using area of squares, area of triangles and trapezoids, and by dissection. Students will then be asked to apply what they have learned about the Pythagorean Theorem.https://education.ti.com/en/activity/detail/pythagorean-proofs_1
Pick's Theorem
Using the TI-Nspire grid screen, students will discover Pick's Theorem relating to the area of a polygon with vertices on grid points.https://education.ti.com/en/activity/detail/picks-theorem
