We use Makers Empire as a tool to assist us in teaching 3D printing for young students in grades KG, G1, G2, and G3. We used some of the resources available in Makers Empire lesson library to build our first-year curriculum in which students practice 3D design in a form of Project Based Learning environment. One example of a project that students work on is to design a bag tag and keychain. Students also work on designing bird’s nest, street signs, maze, and printed coins. Within the context of each project, students practice integrating more than one subject area in the same project. Students also check to make sure their design is ready to be printed. Our goal is to unleash the students’ creativity and build their collaborations and problem-solving skills that would help them next to involve 3D printing into their semester projects across the other subjects.
