Residuals- 84
In this activity for TI-84 series, students will investigate a residual plot for a set of data after selecting a regression model. The residual plot is used to justify the choice of a function model based on an analysis of the residuals.https://education.ti.com/en/activity/detail/residuals_84
Creating Perpendicular Bisectors
Construct the perpendicular bisector of a line segment in several different ways and consider the role of circles in the construction.https://education.ti.com/en/activity/detail/creating-perpendicular-bisectors
Determining Angle Measure
Determine the measure of an angle and if larger angles have longer "sides."https://education.ti.com/en/activity/detail/determining-angle-measure
Diameter and Circumference Relationship

NASA - Robonaut 2: First Humanoid Robot in Space
NASA uses robots in many ways to help with space exploration. When it’s possible for robots to perform tasks, rather than people, there are some obvious advantages. Robots do not have to eat, drink, breathe, or sleep. They can perform tasks over and over in exactly the same way without gett...https://education.ti.com/en/activity/detail/nasa--robonaut-2-first-humanoid-robot-in-space
