In the frame of the "Research for innovation", this paper presents the preparation, planning, classroom implementation, revision and wider experimentation of a long term (Grade I - Grade V) innovative teaching sequence on the argumentative approach to probabilistic thinking, conceived in the perspective of the teaching and learning of mathematics in the "fields of experience." It also presents some developments of basic research, which deal with the hypotheses underlying the planning of the teaching sequence and its classroom implementation. In particular, the basic research presented concerns the mechanisms of argumentative construction of probability knowledge in the classroom: three mechanisms (related to the constructive functions of natural language) will be exhibited, and the conditions for their activation will be discussed.

Abstract
In the frame of the "Research for innovation", this paper presents the preparation, planning, classroom implementation, revision and wider experimentation of a long term (Grade I - Grade V) innovative teaching sequence on the argumentative approach to probabilistic thinking, conceived in the perspective of the teaching and learning of mathematics in the "fields of experience." It also presents some developments of basic research, which deal with the hypotheses underlying the planning of the teaching sequence and its classroom implementation. In particular, the basic research presented concerns the mechanisms of argumentative construction of probability knowledge in the classroom: three mechanisms (related to the constructive functions of natural language) will be exhibited, and the conditions for their activation will be discussed.
