This activity will allow students to use Cabri Jr. to find the sum of the measures of interior angles of convex polygons and visually see how the Interior Angle Sum Theorem works.https://education.ti.com/en/activity/detail/investigating-the-anglesum-theorem-of-polygons
Constructing Quadrilaterals
In this activity, students will construct different types of quadrilaterals from the quadrilateral hierarchy. This activity asks for constructions based on a minimal definition of the quadrilateral. The activity will reinforce the difference between a construction and a drawing.https://education.ti.com/en/activity/detail/constructing-quadrilaterals
Intro to Circles Terminology
Four questions to introduce the TI-Navigator™ and to assess student understanding of basic terms about circles.https://education.ti.com/en/activity/detail/intro-to-circles-terminology
NUMB3RS - Season 2 -"Hot Shot" - A Stab in the Dark
In "Hot Shot," two victims of a possible serial criminal are found. Charlie uses kernel density estimation as a method for predicting a change in behavior to indicate a connection between the victims and the criminal.https://education.ti.com/en/activity/detail/numb3rs--season-2-hot-shot--a-stab-in-the-dark
