## Abstract

There are four questions that will try to answer in this paper, namely (1) what is the context which can be used to introduce negative integers?, (2) how to use the context to make the students construct an understanding of negative integers? (3) how to use context to make the students can also construct about (a) to compare two integers, (b) to order some integers, and (c) to add and subtract two integers, and (4) what are the impacts of the teaching material which designed by the researcher? Learning approach which is used by researcher in this design is realistic approach. The designs which were made by researcher are for fourth grade students. There are three main principles of realistic mathematics approach. This type of research that is used by researcher in this research is the design research. According Akker, Gravemeijer, McKeney, and Nieveen (in Akker, Gravemeijer, McKeney, and Nieveen, 2006), the characteristics of development research are (1) an interventionist, (2) an iterative, (3) a process-oriented, (4) an usability oriented and (5) a theory oriented. According Gravemeijer and Cobb (in Akker, Gravemeijer, McKeney, and Nieveen, 2006) there are three phases in the development of research, namely (1) the preparation of the trial design, (2) the trial design, and (3) a retrospective analysis. The results presented in this paper are the results obtained by the researcher on the first cycle of 2 cycles planned by the researchers. Keywords: integer, realistic mathematics education, and design research
