Reflection: Discourse and Questioning Classifying 3D Figures - Section 4: Classifying 3D Figures


This video is an example of how I responded when a student asked me “What is this 3D figure?”  I guided her through using her “Naming 3D Figures” sheet as a resource.  After watching the video, I realize it would have been more meaningful if I asked the student “How do you know those are the bases?” or “Why aren’t the rectangular faces the bases?”  rather than giving her the definition of bases.  That way I could have more fully understood her thinking and known whether she just guessed that the hexagon faces were the bases.

Classifying 3D Figures

Unit 8: Geometry
Lesson 8 of 19

Objective: SWBAT: • Define and identify edges, faces, and vertices on 3D figures • Identify and classify prisms, pyramids, and curved solids.

Big Idea: How are these two figures similar? How are they different? Students learn vocabulary words so they can precisely classify 3D solids.
