Reflection: Adjustments to Practice Solving Two Step Equations - Section 1: Launch

 

I have found that teaching the "Tell the story of x" equation solving strategy has decreased the prevalence of a few particular errors that I've seen my students make over the years. One of these is when students divide for example, 3x = 45, by 3x on either side instead of by 3. Reduction in frequency of mistakes like this one indicate that the students are not simply learning thoughtless routines, but rather are developing conceptual understanding of how to solve linear equations. So, we continue to develop this approach in today's lesson. Once introduced, I keep the idea alive as long as necessary for my students to develop fluency with equation solving.
