This year, we held a workshop for second grade students and constructed the lesson program for the evaluation and the proposal concerning daily environment on a map and for the construction of a model as a “secure base”. In the making of models, despite the technical problems, we found the definite types to make models: the floor or the roof structure, and the making process itself. In particular, we revealed that children’s sense of security sensibility coexisted with an adventurous spirit. Theme setting and the choice of materials for making the models require further study.
