We created Smart Blocks, an augmented mathematical manipulative that allows users to explore the concepts of volume and surface area of 3-dimensional objects. This interface supports physical manipulation for exploring spatial relationships and it provides continuous feedback for reinforcing learning. By leveraging the benefits of physicality with the advantages of digital information, this tangible interface provides an engaging environment for learning about surface area and volume of 3D objects.
