    Abstract

    In general, students use the algebra notation and cross multiplication to solve proportional problems. However, they may just memorize the procedure without understanding the mathematical concept behind it. In that case the learning process remains meaningless. Therefore, we designed a learning sequence based on the tenets of Realistic Mathematics Education (also known as PMRI in Indonesia), which can help the students to develop proportional reasoning. Twenty nine students of grade 4 in SDN 179 Palembang were involved. They did activities which used money as the context and the ratio table as the tool to do calculation and reasoning. This study is part of a Master Program research which aims to investigate how the ratio table can support the development of the students’ proportional reasoning. But, this paper will focus only on how the ratio table together with the money context can help the students to develop proportional thinking. Design research was used as research methods for this study. The result shows that the money context together with the ratio table may support students to develop their proportional understanding.
