 note = {Students begin to learn geometry based on their own experiences and concrete shapes. However, they eventually must depart from this foundation and develop geometric thinking. Textbooks should be helping students along this process. To this end, we examine whether Japanese elementary school (Grades 1.6) textbooks provide an appropriate foundation for developing students’ geometric thinking. Through an original quasiquantitative or qualitative analysis based on the theory of praxeology, we determine that while first-through fifthgrade textbooks do provide a solid background for developing geometric thinking, fifth-through sixth-grade textbooks do not.},
