The purpose of this study is to know how Lesson Study is to remind professional teachers in the discussion of mathematics learning of material integer multiplication. This research is related to the 2013 learning curriculum and PMRI approach. The methodology used in this study is deskriptive. This research involved all mathematics teachers of class VII Palembang 1 Junior High School. The activities in this study consist of four stages: Plan, Do, See and Re-design. The first stage is designing learning devices such as Lesson plan, teacher instructions, and student worksheets. Second stage applies the results of previous stage.
