Abstract
This research clarifies what matters require consideration when developing teaching
materials, while tracing the process of analyzing mathematical objects. As a specific
example, the patterns of Hakone parquetry were analyzed, and the aims of developing this
into a teaching material as well as its mathematical value were examined. As the patterns
of Hakone parquetry are configured from multiple combinations of point symmetry and line
symmetry of basic shapes, it is thought that even elementary students can devise original
patterns and learn about shape movements. Moreover, in order for teachers to discover
materials that are suitable as teaching materials, it is important that they cultivate the
ability to view natural and societal phenomena mathematically, and actively conduct
relevant investigations and extractions.
