World Population
Students use their handhelds to explore world population data from the years 1950-2006. They will develop various equations to model the data.https://education.ti.com/en/activity/detail/world-population_1
Discovering the Circumcenter and Centroid of a Triangle
The students will find the circumcenter by constructing perpendicular bisectors of the sides of a triangle. They will also find the centroid by constructing the medians of a triangle and discover that the centroid is 2/3 of the distance from each vertex along each median.https://education.ti.com/en/activity/detail/discovering-the-circumcenter-and-centroid-of-a-triangle
Can I Make a Triangle?
This TI-Nspire activity is for the Triangle Inequality Theorem. There are 3 problems that contain 3 segments each. The student tries to make triangles with these segments. They compare the lengths of the shortest to the length of the longest to see if the inequality is true or false. For the...https://education.ti.com/en/activity/detail/can-i-make-a-triangle
Constructing a Pentagon, An Alternative Method
Use the TN-Nspire (OS 2.0) to construct a regular pentagon using lines, rays, line segments, and circles of various diameters.
