This article aims at optimizing Sundanese ethnomatematics learning by improving the modeling and creative thinking abilities of primary school students using teaching materials developed with the Didactic Design Research method. The research subjects involved were first-grade and second-grade students of an Islamic primary school in the city of Serang, Banten with a total of 283 students. The data were obtained using learning obstacles test instrument, Initial Didactic Design and Revised Initial Didactic Design as the instruments. The results of the study show that learning barriers were experienced in the materials of addition and subtraction of numbers. The Initial Didactic Design was revised and developed using Sundanese ethnomathematics learning using endog-endogan and engklek games that resulted in the improvement of primary students’ creative thinking, geometry thinking, and algebra.

Phenomenon the current problem of children in the world, including Indonesia, is not familiar with the benefits of traditional games so that it has an impact on the lack of mathematical achievements, social interactions and physical activity of elementary school students. The purpose of this paper is to examine the development of mathematical understanding, social and physical abilities of grade IV students in elementary school through Sundanese ethnomathematics learning. Thirty-seven students in the experimental class and thirty-eight students in the control class participated in a quasi-experimental design. The instruments used were tested, interviews, observation and documentation. The results showed that the experimental class’s mathematical comprehension ability was better than that of the control class, the formation of social interactions between students, and students-teachers, making students involved in activities so that the learning atmosphere felt pleasant, interesting, and healthy for the students’ bodies. Sundanese ethnomathematics learning with engklekmatika games has proven to be useful for elementary school students because it can develop the mathematical, social and physical abilities of elementary school students.
