The aim of this presentation is to analyze the extensions of the students in a mathematics lesson. The method is the following. Firstly we review the media theory (McLuhan, 1994; Tokitsu, 2012) to extract a viewpoint for mathematics lessons. Secondly we plan and implement a mathematics lesson (Okawa, Ozasa, & Matsuzaki, 2013). Finally we discuss what the students can do or cannot do bodily, and mathematically, by focusing on the viewpoint. References McLuhan, M. (1994). Understanding media: The extensions of man.
