This is a great step-by-step booklet to help derive all the values on the unit circle. Instead of just teaching students to memorize the values, you can show them where they all come from and teach them to derive the unit circle themselves if needed. Print the PDF as a booklet and it can be glued into a interactive notebook with other foldables.

This is a fun "poof" book with steps for finding rational roots of a polynomial. It uses synthetic division to check roots (rather than the remainder theorem). I don't have my own instructions for folding it, but you can Google "how to fold a poof book" and you will find instructions. This is a great resource for Algebra 2 and Pre-calculus.

This is a simple card sort of rational functions. The graphs show asymptotes and holes. The graphs and equations are in order on this page, so you will need to cut them apart and mix them up for students to match. This is a great activity for Algebra 2 students when they are first introduced to rational functions and asymptotes.

This is a foldable for Algebra 2 on asymptotes and holes in rational functions.

This is a poof book leading students through the process of writing a polynomial when given roots. This includes rational, irrational (conjugate) and complex (conjugate) roots. I don't have instructions for the book with it, but you can Google how to fold the poof book.

This challenge has students use the double angle identities and the power reducing identities to solve a riddle. Instructions are in the file.
