Many factors cause the polytechnic students have math difficulties, among others basic math is low, there are too many topics, and lack of time allocation. Therefore, efforts should be made to provide alternative styles of learning. One of the efforts to optimize the learning of mathematics is Math learning by Teaching Aids or APEM (abbreviation of Alat Peraga Edukatif Matematika), especially in Geometry. The Teaching Aids make students to be more active learning in acquiring knowledge and developing thinking. The objective of this research is to describe Geometry topic with Teaching Aids to improve student's abstraction. The results obtained are: (1) The ability of the students is very heterogeneous, (2) Students of Vocational High School (SMK) are more skilful in describing the three-dimension compared to students of Senior High School (SMA), (3) The Teaching Aids of three dimension is needed to solve problems of Geometry,(4) Of the six groups, only one group is answering correctly about the volume of Concrete Construction, and (5) the average score of three problems are 85, 53, and 43. © Published under licence by IOP Publishing Ltd.
