Hangeul and Jeongganbo have a common feature: the spatial frame containing linguistic and musical information, respectively, is made up of squares. This spatial characteristic has the advantage of making it easy to change the writing direction. This study aims to provide a teaching and learning plan in connection with the directionality of Hangeul so that 5th graders of elementary school can become familiar with the vertical format Jeongganbo. To this end, it examined the function of the squares common to Hangeul and Jeongganbo and the process of change in the directionality of layers of squares and identified the learning contents related to Jeongganbo and the form of Jeongganbo presented in the 2015 revised elementary school music textbook. Then, the study presented a teaching and learning plan to familiarize students with the vertical format Jeongganbo newly emerged from the 5th grade of elementary school. The teaching plan designed over a total of 2 sessions placed emphasis on preparing the foundation for ultimately adapting to the transition from the horizontal Jeongganbo to the vertical Jeongganbo through group activities in which students naturally learn various directionality of Hangeul. It is expected that this teaching and learning plan, which has a nature of an integrated curriculum, will expand the breadth of students' musical thinking and experience in elementary school music education and be widely used as educational materials to increase the learning effect on connected subjects.
