## Reflection: Student Ownership Cramers Rule - Solving Systems of Equations - Section 1: Warm-Up

To me, matrices offer the easiest and most efficient way to solve today's warmup problem. However, I am a proponent of allowing a student to choose the approach that is most comfortable to him/her. If a student feels that they can be more precise or more efficient an algebraic method, such as linear substitution, I allow them to do that. It is important that students make reasoned choices about the tools that work best form them, and, apply them well (MP2, MP5).
