All 4 assignments can be used at socrative.com and the socrative share numbers are included in the files. The assignments can just be printed and done on paper, though.


Introduction #1 is a 38 page file. The system of equations ax+by=c and dx+ey=f is solved for y. The student should see why the formula for the determinant was developed based on this outcome. There are 7 formative assessment questions in this file.

Introduction #2 is a 15 page file. The emphasis is using Cramer's Rule to quickly determine if a system has 1 solution, no solution or infinitely many solutions.

The student 1 page printable is information based on Introduction #2.




Assignment #1 is a 15 question multiple choice assignment. The student is asked to values of determinants and to set up ratios of determinants by Cramer's Rule. It is on 1 page for easy printing.

Assignment #2 is a 15 question multiple choice assignment. The student is asked to find values of determinants, match a system of equations to ratios of determinants, and use Cramer's Rule to determine if a system has 1 solution, no solution or infinitely many solutions. It is on 1 page for easy printing.

Assignment #3 is a 15 question short answer and multiple choice file. The student is asked to find values of determinants, the value of the numerator and denominator in Cramer's Rule and to solve for a variable using Cramer's Rule. It is on 1 page for easy printing.

Assignment #4 is a 15 question short answer and multiple choice file. It is a cumulative assignment based on assignments #1 through #3. It is on 1 page for easy printing.
