Manual Fit
Students manipulate parabolas so that the curve matches a set of data points.https://education.ti.com/en/activity/detail/manual-fit
Defining the Parabola
The teacher will graph a horizontal line and plot a point using TI-Navigator™, and the class will provide the points that create a parabola.https://education.ti.com/en/activity/detail/defining-the-parabola
Buying Your First New Car!
With a high interest topic, this activity graphs an exponential "decay" (depreciation) with a linear graph (car payments) and finds the intersection between the two graphs. Students groan when they watch their new cars "decay."https://education.ti.com/en/activity/detail/buying-your-first-new-car
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
Sequence Investigation
Students use the calculator to create an arithmetic sequence and explore the effect of each variable in the formula of the nth term of an arithmetic sequence.https://education.ti.com/en/activity/detail/sequence-investigation
Geometric Sequences & Series
Students find common ratios of geometric sequences on a spreadsheet and create scatter plots of the sequences to see how each curve is related to the value of the common ratio and/or the sign of the first term of the sequence.https://education.ti.com/en/activity/detail/geometric-sequences--series_1
The Calcumites are Coming! - TI-83
Students model the growth of a population and compare ideal growth with a population whose growth is limited. They use technology to find exponential and logistic regression equations and use them to plot models.https://education.ti.com/en/activity/detail/the-calcumites-are-coming--ti83
