This is a collection of common example surfaces from classes in multivariable calculus. Students in these classes often find it difficult to visualise a surface given the equation for it, but these models will make it a lot easier to see what's going on! They show the contour lines when you slice each surface with horizontal planes, together with eight radial curves. The small versions of the surfaces are available as a set, and the large versions individually. These are currently in use at Swinburne University of Technology in Melbourne, Australia.
