Mathematics education filled with abstract concepts, the use of teaching aids is important to increase students’ understanding by giving the concrete experience of those concepts. This article aims to introduce and express the importance of Orthogonal Projector Kit (OPK) to the parties that involved in the education system. Many teaching aids have been studied and developed to help students’ understanding the topic Plan and Elevation, but most of them are software for computers that cannot be touched by students. Therefore, OPK was created to enable students to touch and feel the objects that they need to draw and also give them a concrete experience through this concept.OPK consists of an orthogonal projector (OP), colored skeleton blocks (CSB) and a module for teaching and learning by using it.
