This research aims to develop the mathematics instruction using color chips at elementary school based on Lesson Study. This research was conducted at fifth grade of State Elementary School 23, Padang Timur. The development is adapted from Plomp's model. There are three phases of the development: preliminary research, development/prototype phase, and assessment phases. This research is focused on development/prototyping. The first step of the research is to distribute questionnaires to three teachers for the sake of getting some information about the problems in mathematics instruction at the school. The problem is that the teachers still have the difficulties in showing the real process of addition and subtraction operations on the integers. The second step is to prepare the color chips and create the booklet about the use of color chips. In this prototyping phase the booklet is corrected by the teacher and expert. This phase had micro-cycle until the teacher and the students find the booklet useful. In the first prototype, validation is conducted by self evaluation and expert's review. After the revision of the first prototype, the second prototype is created, and then it is used to know its practicality through implementation in small group evaluation.
