Abstract
This study was a qualitative research. The purpose of this study was to study the teachers’ teaching practices in guiding students’ Mathematical ideas of multiplication toward meeting lesson objectives in classroom using Lesson Study and Open Approach. It focused on the teaching analysis and the classroom observation. The target groups consisted of the teachers from Lesson Study team and the Primary 2 students of Tonkla School, Chiang Mai. The data was collected from video records, pictures, observation forms, lesson plans of number nine’s multiplication and students’ worksheets. Analysis methods were video analysis and Descriptive Analysis was used to present the information. From the study, the teacher created the lesson plan and realized about the students’ Mathematical ideas on multiplication, then the Open Approach was used for teaching. The teacher mentioned to use the open-ended problem relating to the students' routine to encourage the students in applying. After that, the teacher surveyed the students’ Mathematical ideas on multiplication to order and link to the process of Whole Class Discussion and Comparison; from the one-to-one counting to the operating on the operators through the Questions and the Summarization between teacher and students toward Meeting Lesson Objectives.
