In 1941, the 5th national elementary arithmetic textbook ‘Kazu-no-Hon [Book of Numbers]’ was published. I make comparison between the textbook and the previous textbook, the 4th elementary arithmetic textbook ‘Jinjo Syogaku Sanjutsu [Ordinary Elementary Arithmetic]’. Through the comparison, I revaluate the teaching materials for geometry in ‘Kazu-no-Hon’. Between those textbooks, I can see significant difference. In ‘Kazu-no-Hon’, there are the materials that students can observe the changing shapes and those relationships through moving actual objects. They are characteristic materials found only in ‘Kazu-no-Hon’. And they reflect the intention to develop children’s figural concepts before starting to learn geometrical definitions, properties and construction of figures.
