A1.ACE.2 Create equations in two or more variables to represent relationships between quantities. Graph the equations on coordinate axes using appropriate labels, units, and scales. (Limit to linear.)

A1.AREI.5 Justify that the solution to a system of linear equations is not changed when one of the equations is replaced by a linear combination of the other equation.

A1.AREI.6b Solve systems of linear equations using linear combination.

Solving systems of equations by elimination involves manipulating equations within the system to eliminate one of the variables by adding or subtracting the equations. This process creates a new equation with fewer variables, making it easier to solve for the remaining variables.

Students should have the abilities to perform basic arithmetic operations.

Students worked in pairs, each pair having a varied level of understanding. Their task was to complete an escape room challenge consisting of five puzzles. These puzzles were specifically designed to require students to solve systems of equations by elimination, fostering creative problem-solving approaches. This assignment not only encourages active participation but also facilitates peer teaching and collaboration. 

While the assignment was not formally graded, students received a participation grade for their engagement.
