One Step at a Time
Students solve one-step equations involving addition and multiplication by substituting possible values of a variable.https://education.ti.com/en/activity/detail/one-step-at-a-time_1
Ride the Rollercoaster
In this activity, students will use polynomial regression to develop and assess the fit of equations modeling data. The equation models are then evaluated for reasonableness in their use for extrapolating beyond the given data sets.https://education.ti.com/en/activity/detail/ride-the-rollercoaster_1
Parametric Projectile Motion
Students will understand how changing the initial velocity and the initial angle change the path of a projectile. Students will be able to write the parametric equations for the path of a projectile.https://education.ti.com/en/activity/detail/parametric-projectile-motion
Breaking Up is Not Hard to Do
Students split rational functions into sums of partial fractions.https://education.ti.com/en/activity/detail/breaking-up-is-not-hard-to-do
Rational Functions
Students investigate the graphs of functions of the form y = 1/(x - a). They will discover that the graph of such a function has a vertical asymptote at x = a, and a horizontal asymptote at y = 0. They will investigate the graphic and numeric consequences of such asymptotic behavior by observing ...https://education.ti.com/en/activity/detail/rational-functions_2
Count the Differences
Students are given data, asked to find the finite differences, and then use this to find a polynomial that models the data.https://education.ti.com/en/activity/detail/count-the-differences_1
