Cracking the System
equations · solving systems of linear equations
To solve systems of 2 linear equations in 2 variables using elimination and substitution [8.EE.C.8c].
Cracking the System is a Grade 8 systems of equations game in which card draws generate the coefficients and constants for two linear equations. Students build a system, then solve it using elimination or substitution and interpret the resulting ordered pair or solution type. Because each draw creates a new system, students get varied algebra practice without working through the same preset equations.
Use it with partners or a small group after students know both major solving methods. The generated equations invite comparison of strategies: Which method is more efficient here, and how can you verify the solution?
