Publication Date



Difficulties inherent in representing 3-­D objects on 2-­D media can present barriers to student understanding of mathematical concepts as they relate to solids. All students, but particularly those who have visual impairments, can benefit from a tactile representation of mathematical objects. Because 3-­D printers are becoming more commonplace and can generate a wide variety of objects, the ability to create real hands-­on objects is no longer out of the question. The authors will show how tactile 3-­D objects can enhance mathematical experiences in Calculus and provide some helpful tips for good quality 3-­D printing on Cube and MakerBot Replicator 2.
