### PRODUCT DESCRIPTION

Using matrix theory and Cramer’s Rule to solve systems of equation is intimidating to most students when first introduced. This activity can be used to demonstrate the ease in which determinants can be computed and used to solve system of equations. It includes 15 systems of equations problems for the student to solve using Cramer's Rule. Each problem has a template that forces the student to show the work for each determinant that is needed and the other arithmetic required to obtain a solution. The first three problems are set up so that the student can check their work solving the same equation using elimination. After working through this activity most students told me they felt Cramer’s rule was the easiest method to solve systems of equations!
