Then, all three midseg...https://education.ti.com/en/activity/detail/midsegments-of-triangles_1
Interior & Exterior Angles of a Triangle
In this activity, students will measure interior and exterior angles of a triangle and make conjectures about their relationships.https://education.ti.com/en/activity/detail/interior--exterior-angles-of-a-triangle
Points on a Perpendicular Bisector
Students will explore the relationship between a line segment and its perpendicular bisector. The concept of a point that is equidistant from two points is illustrated.https://education.ti.com/en/activity/detail/points-on-a-perpendicular-bisector
NASA - An Astronaut in Motion
To better understand how astronauts function in their suits and their environment, researchers at NASA Johnson Space Center’s Anthropometry and Biomechanics Facility (ABF) are studying motor control and evaluating human physical measurement, variation, and movement. To study human movement, ABF r...https://education.ti.com/en/activity/detail/nasa--an-astronaut-in-motion
Back to the Basics
Students learn and use the basic undefined terms and defined terms of geometry. The activity does include some drawing practice on the handheld.https://education.ti.com/en/activity/detail/back-to-the-basics
Application of a Circle: Angles and Arcs
Students use the properties of circles, angles, and arcs to help design a courtyard with a star-shaped design.https://education.ti.com/en/activity/detail/application-of-a-circle-angles-and-arcs
Are You Normal Size?
Students use established body proportions to see if their own proportions are normal.https://education.ti.com/en/activity/detail/are-you-normal-size
Basic Trigonometric Transformations
This lesson involves manipulating sliders to change the values of parameters in trigonometric functions and determining the effect that each change has upon the shape of the graph.https://education.ti.com/en/activity/detail/basic-trigonometric-transformations
Position, Distance, Velocity
Provide a position function to "drive" the rectilinear (straight line) horizontal motion of an object.https://education.ti.com/en/activity/detail/position-distance-velocity

Breaking Up is Not Hard to Do
In this activity, students will split rational functions into sums of partial fractions. Graphing is utilized to verify accuracy of results and to support the understanding of functions being represented in multiple ways.https://education.ti.com/en/activity/detail/breaking-up-is-not-hard-to-do_1
Crossing the Asymptote
This lesson involves determining when the graph of a rational function crosses its horizontal asymptote.https://education.ti.com/en/activity/detail/crossing-the-asymptote
Rational Functions
In this activity, students will discover, or re-discover, the connection between a rational function, transformations, and both vertical and horizontal asymptotes.https://education.ti.com/en/activity/detail/rational-functions_1
Coin Toss
Students will run two experiments that simulate pouring out coins from a bag.https://education.ti.com/en/activity/detail/coin-toss_1
Identifying Sinusoidal Graphs
This lesson involves examining graphs, or partial graphs, of sinusoidal functions to determine the values of their parameters and to express them in various ways involving sine and cosine functions.https://education.ti.com/en/activity/detail/identifying-sinusoidal-graphs
Stay Tuned Lab Sound Waveform Models
