This paper is a part of a long-term study examining the didactic transposition process of the
quadrilateral knowledge. It aims at examining the relationship between the knowledge officially
proposed by school curriculum and the knowledge planned to teach by a novice mathematics teacher
regarding quadrilaterals in 5
th grade. We analyzed the curriculum and data of the interview with a
novice mathematics teacher. The data obtained shows that the knowledge planned to be taught is
consistent with the knowledge proposed in the curriculum, except for the relationships between
quadrilateral types. The findings reveal that the role of the teacher’s knowledge is critical to the
knowledge to be taught
