This product is designed to cover both methods used for determining 3rd order determinants, the diagonals method and the expansion-by-minors method. I teach both methods in my Honors Algebra 2 class, but the only method covered in my book is the diagonals method. Students continuing in higher level math classes need both.
* 2nd Order Determinants
* 3rd Order Determinants
* The Diagonals Method
* The Expansion-by-Minors Method
* Triangle Area Formula using Determinants
Guided notes and an Answer Key are included. The instruction usually takes 30 minutes with the rest devoted to the problems. Most students finish part of it as homework.
