The nice thing about looking for OER in other languages is that you realize how extensive the diaspora of certain languages – usually the result of colonialism and subsequent language policies – actually is. ┬áThis Geometry module in Portuguese actually comes from the African Virtual University, which incidentally houses OER in English, French and Portuguese. ┬áThe module is available as pdf and doc versions, the latter making it easier to run through a Google translator and for remixing or adapting. ┬áThe module is for 120 hours of study at an undergrad level. ┬áThe module seems to contain what we would consider ancillary resources in the form of exercises, which is a useful resource in itself.
