The paper aimed to clarify the innovative lesson study learning activities for enhancing Grade 2 students’ multiplication conception. The paper provided the lesson study environment which allowed the primary school teacher could develop the lesson plan about multiplication conception through open approach. Regarding on the open approach, the cycle of lesson study focused how to provide students’ openly constructing their meaning of multiplication based on everyday life situation. The lesson plans about multiplication concept were developed based on the situations of calculating amount of things in groups that each group has same number of thing. The paper will highlight these situations in order to visualize how they allow students to construct their concepts of multiplication and to generate multiplication symbol. The paper has implications for developing constructivist mathematics learning for Grade 2 students.
