Transform 2D shapes to make a stack of 3D objects. Start with a circle, triangle, square or rectangle. For example, spin a circle on its central axis to form a sphere or extrude it to form a cylinder. Choose a shape and imagine it being spun around an axis or extruded. Picture which 3D block your 2D shape will make. This learning object is one in a series of six objects.
