This activity is appropriate for Algebra II or Precalculus.https://education.ti.com/en/activity/detail/investigating-logistic-functions-and-applications
Linear Equation Games: Activity #7 Blackblobs
This is the Nspire version of the old DOS program 'Green Globs'. Students are given random points in which to find their own equations. The more points they go through with one line, the better their score.https://education.ti.com/en/activity/detail/linear-equation-games-activity-7-blackblobs
Inverse Trig Functions
This activity works backwards by giving students the inverse functions and having them discover how they relate to the original functions. By tracing along the inverse function, data is collected and then plotted on a statplot. The variables are then switched on the statplot. The new plot and ...https://education.ti.com/en/activity/detail/inverse-trig-functions
NASA - Rendezvous For Two
When the space shuttle launches from NASA Kennedy Space Center, it must launch within a certain time frame (called a launch window) in order to successfully dock with the ISS. Launch windows are calculated so that the space shuttle will reach an orbit that is slightly lower than the ISS, but in t...https://education.ti.com/en/activity/detail/nasa--rendezvous-for-two
