Learning to Do Linear Regressions
This activity compares children's age to height to teach linear regressions. The handout includes notes for students and teachers with a step-by-step lesson on how to do 3 types of linear regressions - Best Fit line, Median Median Line and Least Squares Line.https://education.ti.com/en/activity/detail/learning-to-do-linear-regressions
Depreciation
In this activity, students perform computations involving depreciation of assets. They will study methods such as Straight line depreciation, Sum of the digits method and Double declining balance depreciation.https://education.ti.com/en/activity/detail/depreciation
Continuous Compounding
In this activity, students deal with financial computations, where the interest is compounded continuously. Depending on the length of each compounding period, students will determine the number of compounding periods.https://education.ti.com/en/activity/detail/continuous-compounding
Trains in Motion
Students will make observations about the motion of two objects. They will compare and contrast this motion and consider how it corresponds to a graph representing distance as a function of time.https://education.ti.com/en/activity/detail/trains-in-motion
Transformations: Two Functions or Not Two Functions
Students create original artwork using all functions and conics studied throughout the course. Lines and absolute values, conic sections and whatever else they can stick in a "y=" are combined with some calculator tricks to make works of art that the students are really proud of.https://education.ti.com/en/activity/detail/transformations--two-functions-or-not-two-functions
Light at a Distance: Distance and Light Intensity
In this activity, students will use a light sensor to record the light intensity at various distances from a bulb. They will compare the data to an inverse square and a power law model.https://education.ti.com/en/activity/detail/light-at-a-distance-distance-and-light-intensity
Let's Play Ball with Families of Graphs
This activity is designed for students to use real-time data to generate a family of parabolic graphs. The data set will be generated by graphing the heights of a ball bounce with respect to time. Students will determine the regression equations to the graphs and determine their relationships. ...https://education.ti.com/en/activity/detail/lets-play-ball-with-families-of-graphs
Building curves
Students approach performing the basic operations on the polynomials from a graphical perspective. Given the graphs of two functions, they plot points that lie on the graph of the sum of the functions and draw conclusions about its behavior. Next, they calculate a regression to fit the points the...https://education.ti.com/en/activity/detail/building-curves
Exploring Circles
Explore the relationship between the center and radius of a circle and the equation of the circle. Collect data and determine regression equations related to various combinations of data, and use the regression equations to make predictions.https://education.ti.com/en/activity/detail/exploring-circles
