• Resumen

  • In this paper, I discuss the potential transformations to teach K-12 geometry topics with the technology of 3D Pens, which enabled 3D models to be created instantly via one’s moving hands. I draw on an example of using constructionist learning activities with 3D Pens to teach young children, ‘how tall is the triangle?’
