Reflection: Staircase of Complexity Geometric Means - Section 3: Discussion


One of the things I have been working on in my practice is trying to only reteach content students should already know in service of the current common core standard.  This comes up in this lesson as my students always struggle with the radical sign and taking the nth root of both sides in order to "undo" the equation.  Depending on the class, I may have to spend a significant amount of time revisiting this content but it is essential for them to understand geometric sequences.
