In problem solving process, the students leadtheir entirecapability. The competencies which are used in problem solving namely rationality, creativity, and other thinking abilities. Problem solving needs conceptual understanding ability (conceptual knowledge), ability to do inter-conceptual relationship (principle and procedure), accuracy, and student’s mental readiness. Problem solving is an important aspect in learning mathematics. A student called mastering certain mathematics lesson if he/she has a problem solving skillwhich is contained in the lesson. Problem solving skill is necessary to be implemented to the student’s competency from the elementary school. Problem solving skill is need to be trained and be accustomed to the student as early as possible.It is significant because the students haveskill to solve mathematical problem when they have many experiences. The experience of mathematical problem solving will be provision for facing daily life problems. Problem solving skill relates to lessons in curriculum. It is in order to see how far the student’s skill in calculating, remembering, and applying mathematical formula relevantly. The results of mathematical problem solving ability of primary school students in the category which is equal to 56.50% of the 915 questions. Problems that can be completed correctly that as many as 517 questions that consists of 392 questions form Algebra, 93 about the form of Geometry, and Algebra 32 question form with the average time required for 51.1 minutes. In solving the problem, students will have a motivation to use continuously their knowledgeif the result that obtained is a solution from the problem they faced.
