Although artistic and delicate shapes can be made in creative design teaching on site, standard sizes should be specified for some necessary types of objects, in order to provide guidance for students and teach them techniques. It can be found that many technical tutors fail to teach students the quantitative characteristics of mathematics in making a jelly flower. As a result, it is difficult for novices to select accurate types of flower needles, and to know that different flower buds and petals should be created by injecting liquid concoctions with different and precise angles, depths, and sizes. Petals in different lengths should also be designed for tutors to teach students techniques with precise information. As no flower needles or concoction ratios similar to those mentioned above are provided in films, teaching files, or books, it is necessary to teach the flower piping with different angles, lengths, depths. This study aims to provide students with accurate numbers and angles that follow the technical steps and methods to design and make delicate floral jelly cakes, as well as the use of various quantitative characteristics with explanations through graphs and text. The results of this study provide novices with the required techniques to make these cakes. This study can help tutors learn from examples and engage in teaching suitable and scientific techniques, and its result can be taken as the basis for the development of a professional teaching course in making floral jelly cakes.
