Reflection: Checks for Understanding Using Nets to Find the Surface Area of Prisms - Section 2: Lesson Middle


The independent practice section asks students to draw a net of various prisms.  Some students had a difficult time drawing the precise net.  I think that it is okay for student to draw the separate faces and label the sides without drawing a true net.  In my thinking, the purpose of a net is to help students see the component parts of a prism and what the dimensions of those parts are.  So I accepted drawings that were not actual nets as long as the correct number of component shapes were given with proper dimensions.
