Research Abstract	A development of a 3D object is well used as teaching materials. At an elementary school, the educational method that cutting papers with scissors and folding them is well known. Later, although a development of a 3D object is again used by cutting of solid or a sketch, in the school education after it, a development of a 3D object hardly appears. In this research, we restrict to development of a 3D object which is frequently used in school education, and developed the teaching materials which make a 3D object from a 2D unfolding paper using the computer.
