Abstract

In the national curriculum of Indonesia, the level of elementary school education is required to be able to master the material geometry fields and space geometry that in fact also requires spatial ability. At the stage of thinking in the age of elementary students need a concrete object to realize abstract thinking that is in the minds of students so that thought becomes concrete or more real. The purpose of developing 3D-Geometric (3Dmetric) that students more easily understand three dimentional space specifically into the spatial abilities of their students. This research has used Design Research method that is part of research and development method that protrudes toward the development of instructional materials and or learning materials. This study uses Hypothetical Learning Trajectory as a reference in research and several supporting instruments of development. The result of this research is that media 3Dmetric can increasing spatial ability. Students can also distinguish between diagonal space and diagonal side of space.
