Reflection: Developing a Conceptual Understanding Completing the Square Methods & Practice - Section 4: Investigation & Closing

 

Though most of my lessons focus on conceptual understanding, I think this is a good point in the unit to give students some time to build their procedural skills.  Completing the square is a challenging task for many students and up until now, we've mostly been looking at it from a conceptual standpoint. At this point, I like to take a step back and show them some more formal "methods" or procedures so they can become fluent at this skill.  I think there is a time and a place for skill based math work and it's all about finding the right balance.
