Students use 3-dimensional materials to create a simple 3-D object. They think about different ways the object could be sliced. Students choose one way to slice the object, and draw the sliced shape on paper or computer. Using a 3-D computer program, students construct an object that makes a connection between an object from nature and a constructed object. Full Review »
