Reflection: Accountability Order of Operations - Section 2: Intro to New Material


The problems in this lesson have many steps, which must be completed in a specific order.  I tend to use a lot of cold call in this and the next lesson.  Cold calling serves a number of purposes:  

  • it's engaging for students (I use popscicle sticks to pull names, so that students know it is random and they're eager to hear which name I call next)
  • it holds students accountable (everyone has to have their brains 'on' and be ready to potentially answer the next step of the problem)
  • it serves as a quick check for understanding (I get to hear from many voices, and can see if/where there are any misconceptions before students start to work with less support from me)
