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
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
Convergence of Taylor Series
A Taylor Series for a function becomes the function as the number of terms increases towards infinity.https://education.ti.com/en/activity/detail/convergence-of-taylor-series
Tesselations
In this activity students will explore what causes some regular polygons to tesselate. They will explore sketches of regular polygons, measure the interior angles, and test to see whether the shapes tesselate.https://education.ti.com/en/activity/detail/tesselations
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 of Functions
Students will manipulate piecewise functions to make them continuous. Once students create a continuous function, they will calculate derivatives to determine if the function is also differentiable.https://education.ti.com/en/activity/detail/continuity-and-differentiability-of-functions
The Radian Sector
In this activity, students will explore properties of sectors. Students will derive the formula for the arc length of a sector and the area of a sector.https://education.ti.com/en/activity/detail/the-radian-sector
Shortest Distance
Students will discover, through exploration, that the shortest distance from a point on a line to the origin is a measure of a perpendicular line segment. You will investigate this minimization problem and support the analytical explanations with interactive explorations.https://education.ti.com/en/activity/detail/shortest-distance
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
