It is customary to select a small number of countries so that the international mathematics community may gain a closer knowledge on the state and trends of mathematics education in those countries.
National representatives of those countries are asked to organize the presentation. An exhibition, video shows, cd-roms and so forth may accompany a national presentation.
ICME- 11 will have a combination of regional and national presentations of mathematics education. Representatives of Latin America and the North African Arab countries as regions are being asked to organize presentations. China, Iran, and The Netherlands as individual countries have already accepted the invitation.
