Application of 3D Printing in the Study of Quadrilaterals in 5th Grade

Ideas for creating jewelry with basic figures – quadrilaterals, through 3D printing are presented. Applying knowledge about the types of quadrilaterals to create authors works supports the formation of knowledge and skills about the basic characteristics of the main types of quadrilaterals. The presence of STEM centers in a number of Bulgarian schools and, accordingly, 3D printers facilitates the implementation of these ideas. The use of basic geometric figures to create unique works suitable for 3D printing supports the simultaneous development of mathematical and engineering competence.
