Abstract
The purpose of this study was to examine the viewpoint to organize the Child,s play which was the realization of child,s emotion into the work. The author arranged the connection between play and work with the framework of the concept of "Occupation" by J. Dewey, and examined the hypothesis. It was to reconstruct the play into the constructive activ-ity. The author selected "Maritsuki" from the Child,s play with song. The teaching-learning plan of child,s making "Maritsuk" was carried o-ut in the 2nd Grade Class Ikeda Elementary School. In this work, they played activity, through their constructive instinct,and then they made the Maritsuki of their own. In the result, child,s "Maritsuki" had musical contents, which was ba-sed on the children,s own living experience and thier communicating ins-tinct. They made progress not only in their musicul ability but also in their social ability. The work was formed by reconstructing the play to the constructive activity.
