The Classic Box Problem - Exploration
This lesson takes a classic optimization problem and uses the dynamic linking capabilities to visualize the problem in multiple representations: diagramatic, geometric, graphic, numeric.https://education.ti.com/en/activity/detail/the-classic-box-problem--exploration
Algebra Skills Review: 3-in-1 Activity
This versatile activity set includes a printable scavenger hunt, a Google Slides review, and practice sheets.https://education.ti.com/en/activity/detail/algebra-skills
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
Critical Points and Local Extrema
Visualize the connections between the critical points and local extrema.https://education.ti.com/en/activity/detail/critical-points-and-local-extrema
Tessellations
Students will explore tessellations of triangles and quadrilaterals. They will use the transformation tools of symmetry, reflections, rotations, and/or translations.https://education.ti.com/en/activity/detail/tessellations_1
Segment Addition Postulate
The purpose of this handout is to provide students an opportunity to learn the keystrokes involved using the TI-Nspire and to verify the Segment Addition Postulate.https://education.ti.com/en/activity/detail/segment-addition-postulate
Continuity and Differentiability 2
Explore piecewise graphs and determine conditions for continuity and differentiability.https://education.ti.com/en/activity/detail/continuity-and-differentiability-2
The sum of the interior angles of regular polygons
The students will construct triangles within regular-sided polygons to determine the sum of the interior angles. They will then, using statistics, create a linear regression to determine the relationship between the number of sides of a regular polygon and the sum of its interior angles.https://education.ti.com/en/activity/detail/the-sum-of-the-interior-angles-of-regular-polygons
Shortest Distances
Students will explore three situations involving distances between points and lines. First, the minimum distance between two points leads to the Triangle Inequality Theorem. Then, the shortest distance from a point to a line is investigated. Finally, students find the smallest total distan...https://education.ti.com/en/activity/detail/shortest-distances
Side Length, Perimeter, and Area of a Rectangle
Explore the effects of changing base (or height) of a rectangle on it's perimeter and area.https://education.ti.com/en/activity/detail/side-length-perimeter-and-area-of-a-rectangle
