The concrete thing is manipulated by the students to bring the concrete concept become the abstract concept to help the students understand about the concepts by using interaction between the students, students and the teacher and, students and the around environment.
Hans Freudental in Sugiman (2007) said that mathematics is the human activities and must be related in reality. When the students do the teaching learning process especially in mathematics teaching learning process then in themselves is happened the mathematics process.
