Geometry through 3D Printing

This unit is designed to engage 10th grade geometry students with concepts relating to transformations, through the use of OpenSCAD computer software and a 3D Printer. The unit will help students to apply and expand their existing knowledge of transformations of figures on a coordinate plane to create and manipulate geometric solids in a 3D coordinate system.
