This educational proposal is built up from a varied set of disciplines with different viewpoints which manage different approaches to rivers: hydrology, ecology, land uses, cultural heritage, or fluvial landscape. Nowadays, traditional approaches are misleading, and they promote conflicts between the required knowledge and what society demands. Thus, didactic innovation on an integrated base is required from early educational ages. Here are presented some didactic strategies that could be implemented from elementary schools, with students from 6 to 12 years old. The aim is to establish an approach and procedures for river teaching and help to develop proposals for teachers, which eventually could be used in class. The development of these guidelines is implemented by the identification of fluvial functions along specific items suggested.
