In the year 2015, regional economic integration in the Association of South East Asian Nations [ASEAN] Community will take
place, and the diversity of students in ASEAN Community classrooms will inevitably increase. In Thailand: one of the countries
belonging to the ASEAN group, there is a movement towards educational readiness preparation. However, the movement is not
specific regarding classroom practices, and Thai mathematics teachers have not yet been well prepared to deal with such
diversity. In this paper, first the need for preparing teachers for diverse classrooms in Thailand is discussed. Then, issues related
to diversity in mathematics classrooms and preparing mathematics teachers to teach diverse groups of students are introduced.
Finally, conclusions and suggestions are made.
