Understanding the forms wherein racism operates in mathematics teaching and learning practices requires taking into account the local meanings of race and the composing features of racialized social systems.The mechanisms through which racism is reproduced within school mathematics across racialized social systems differ subtly, but manifest themselves in strikingly similar ways.So, while the meanings of race are malleable and locally situated, its production of privilege, power, exemption, and disenfranchisement is stable.Likewise, the still widespread view that mathematics and mathematics education are non-political practices has allowed little interrogation of how racialized social practices permeate mathematics education.The minimization of attention to racism in international mathematics education research is perplexing, particularly in contexts characterized by long histories of anti-Blackness and colonialism and in other contexts that are facing increased levels of xenophobia, anti-immigration, and contestations of national identity.The Discussion Group was an opportunity to create awareness on these issues and to push for analyses of race and racism in local, global, and international contexts.We aimed at facilitating discussion among colleagues around the world on experiences of racisms and racialization of mathematics education.We also intended to find and imagine different ways of collaborative work that move the field forward and have an impact on research, practice, and policy.Around 30 participants mainly from the United States, England, Brazil, South Africa, Portugal, and Germany took part in the discussions.An initial recalling of experiences that could be seen as instantiations of racism in relation to math education was a starting point for recognizing the overt as well as the subtle ways in which racism is instantiated and becomes present.In some contexts, being the "black body" is associated with incapacity for mathematical thinking.In other contexts, the color of skin as a marker intersects with belonging to
