This The Remainder Theorem Using TI-Nspire CAS lesson plan also includes:
Investigate the Remainder Theorem in this algebra lesson. Explore the relationship between the remainders of polynomial division and the function. Each of the four problems gets progressively more complicated. This might be a great lesson to do as a whole class using a teacher's CAS computer software if high schoolers don't have a CAS version of the TI-Nspire.
