The new Georgia Performance Standards for mathematics is modeled after (based on?) the 1989 Japanese Course of Study. One of my research interests as a mathematics educator is mathematics education in Japan, where I am originally from.
From time to time, I plan to post my own interpretation of the GPS based on my study of the Japanese curriculum (and my interactions with Japanese mathematics educators at all levels).
I was involved in the translation of a Japanese elementary mathematics textbook series. My colleagues and I have also translated an elaboration document of the Japanese standards that the Ministry of Education published. Both of those materials may be obtained from Global Education Resources (http://www.globaledresources.com/).
