Abstract
This study aims to describe the mathematical representation of geometry flat side at SMP Negeri 02 Baras. This type of research is qualitative research. The subjects of this study were grade IX students of SMP Negeri 02 Baras which consisted of one student with high math ability and one student with low math ability. Data were collected by giving assignments and interviews. The results of this study indicate that: (1) Students^ mathematical representation on visual representation indicators for students with high math abilities solve problems by drawing geometric patterns to clarify and facilitate completion, students with high math abilities make geometric patterns according to the given problem, namely drawing cubes and pyramids, while students with high math abilities Low math does not draw geometric patterns to clarify and facilitate completion. (2) Students^ mathematical representation on symbolic representation indicators for students with high and low math abilities solve problems by involving mathematical expressions, namely determining the formula used using mathematical symbols and performing number operations correctly. (3) The mathematical representation of students on verbal representation indicators for students with high mathematics abilities explains the steps for solving mathematical problems with written or oral texts, while students with low mathematical abilities are still wrong in determining the steps for completion
