Table 1 A summary of the types of questions in student assessments

Category	Sub-category	Number of items	Sample question	Total items
Simple: Determining the number of faces, vertices, or edges in a given prism or pyramid	Faces (SF)	5	How many faces does an 8-gonal pyramid have?	15
	Vertices (SV)	5	How many vertices does an 11-gonal prism have?
	Edges (SE)	5	How many edges does a 9-gonal pyramid have?
Advanced: Working backward given the number of faces, vertices, or edges in a prism or pyramid	Faces (AF)	4	A solid has 14 faces. This solid could be a _____-gonal prism or_____-gonal pyramid.	12
	Vertices (AV)	4	A solid has 9 vertices. This solid could be a _____-gonal prism or_____-gonal pyramid.
	Edges (AE)	4	A solid has 18 edges. This solid could be a _____-gonal prism or_____-gonal pyramid
