This study clarifies the process of generating meaning in lower elementary Warabe-uta-learning classes that introduce the creation of play by focusing on body function. First, we reconsidered the meaning generation process as formulated by Dewey by focusing on body function. Then, on the basis of the perspective gained from this process, we analysed Warabe-uta-learning classes that incorporate the creation of play in the form of bodily expression. From the results of our analysis, we conclude the following about the process of generating meaning in lower elementary Warabe-uta learning. 1) While modifying a child's play, that is, transforming and generating play, each child's body accepts and simultaneously embodies a 'quality'. 2) The modification of play predicts a shared 'sense' between the subject and others. 3) Play directed at a shared 'sense' is further modified, and within that, specific play is selected and repeated. 4) The selected and repeated play is established as an expression of a quality, 'signification', which is identified by the play at the same time as it becomes 'significance' to the group, and a 'sense' is then generated and shared.
