Reflection: Data Analysis Solving Multi Step Equations: Special Cases (Day 3 of 4) - Section 2: Guided Notes + Practice


This lesson stretched my student’s mathematical thinking. Students frequently mistake 0 or decimal answers as no solution. This is a common misconception when only having dealt with one answer equations.  It is critical to stress to students that these cases don’t mean no solution with many counter examples. With this added complex understanding, it also can be a source of error for students to prematurely rush to a no solution conclusion. The face activity invested students in diligently analyzing the equation and their work to be sure their conclusion was accurate. I highly recommend using self-check measures such as this activity with adding new dimensions to previous concepts to ensure correct application with prior knowledge.
