Reflection: Student Led Inquiry Solving Linear Systems of Equations with Elimination (Day 2 of 3) - Section 2: Investigation


This lesson was originally developed after introducing elimination strategies to students because they know that elimination works but they do not know why it works. I created the Elimination Investigation because in previous years I have found that students often are taught how  to do elimination, but why it works is not always explained. The responses of students will drive this activity.  The Matching activity is a great way for student to test how well they have mastered the elimination method. A good modification for struggling students is to take out the solution pieces and only have them match the equations with the multiplication step.
