systems of equations

As I prepared to teach students about working with systems of equations, I reflected on last year’s students and came to a painful realization- there were several students who just never really got what they were doing. Sure, most students got pretty good at using the substitution method or the elimination method to solve for two systems of equations. But even for those who could do well with test questions, did they really understand at a conceptual level what they were doing? It was humbling to realize that for most of them, the answer was probably no. So for the past week I took a different approach to the topic, applying the Discovery Lab approach I’ve seen work so well for other topics. It’s been awesome to see how my students have responded to this Systems of Equations Discovery Lab. [Read more…] about Teaching Systems of Equations with Discovery Labs
