Reflection: Grappling with Complexity Solving Analogous Equations - Section 2: Share

 

Students were getting really lost on question #8 when it got to the step x·log2(5) +1 = x. I had to remind students that log2(5) is just a number (and the coefficient of x) and that if the coefficient were much simpler (like 4x + 1 = x) we would be able to easily solve it. Seeing this simpler equation made sense to most students and was very important for their understanding. I think I would have lost about half of the class without it.
