NHK Gakuen : Space School : Sansu 6 Nen : Ge

The Space School series was an educational series of games created in collaboration by Konami, Tokyo Shoseki (a Japanese Textbook publisher), and NHK (Japan's National Broadcasting Organization) in 1989. The games had been developed to be mathematical teaching tools, each released in two parts ('Jou' and 'Ge'), for elementary school 4th, 5th, and 6th grade math, generating a total of six games in the series each with accompanying textbooks / workbooks to use whilst playing. All games in the series were made for and required the Konami Q-Ta Famicom Adaptor.
