Learning Mathematics about fraction number in Junior High School can be executed across Mathematics Realistic approach. With this approach the teacher give instruction to student to develop the models and then the models as a base to develop formal Mathematics. In the process there are two model that is model of situation and model of mathematic.
Learning fraction number with realistic Mathematics approach, the teacher needs to take not of things as follow:
1. The student need to given an opportunity to explore and reflection the alternative concept about ideas of fraction numbers to increase their motivation in the next teaching learning.
2. The student need to given an opportunity to explore and to get new knowledge about fraction number with shape the knowledge to their self.
3. The student need to given an opportunity to get knowledge as process of change include increasing, creation, modification, smoothing, composing, and rejection.
4. The student need to given an opportunity to get new knowledge about fraction number developed by the student to him self from their experience.
5. The student need to given a chance to learn, do, and implement the fraction number.
In addition the teacher need to self-revitalization so that the teacher can be him self as facilitator, the teacher can develop teaching learning interactively, the teacher can give a chance to the student actively, the teacher can develop the curriculum and syllabi and can linked the curriculum with real world as a physical or as a social, the teacher can develop scenario of teaching learning that is interaction scheme and competence achievement scheme.
