Reflection: Discourse and Questioning Finding the Surface Area of Pyramids Using a Formula - Section 2: Lesson Middle


Problem 7 almost caused a mutiny.  Not really, but I did have students tell me the objective of the lesson was to find the surface area of a pyramid using a formula.  Where was my principal then?  He loves to ask students what the objective of the lesson was.  He expects the students to respond in a mastery objective format - provide the what and how of the lesson.  They never seem to remember all of this when he asks them at recess but they sure threw it in my face today!

It all worked out.  Only after I got them to draw the pyramid and label the dimensions were they able to find a way through the problem.  Good thing because there was an almost identical problem on the exit ticket.
