INTRODUCTION
Learning Mathematics does not only talk about how to acquire a formula, master certain problem-solving process, and/or understand certain definition, argument, and proof.
also deals with how to develop a mathematical thinking pattern (Nunez, 2015.
Waziri.
Saidu, & Musa, 2.
Mathematics learning within the 2013 Curriculum is designed to improve studentAos creativity, innovative thinking, and productivity.
Hence, students could stimulate their creativity inconcerning with the learning environment.
Consequently, students could apply their cognitive, attitude, and psychomotor domains to a greater degree (Ahdianto, 2016.
Imswatama & Lukman, 2.
In the implementation of the 2013 Curriculum, it should employ an instructional media that is appropriate to studentAos characteristics such as attitude, cognitive, and psychomotor domains.
The three domains are simultaneously connecting with the topics studied by the students.
An instructional media is developed to facilitate teacher in delivering lesson and allow students in understanding it during the learning process (Saputra & Fiazah, 2.
In addition, an instructional media should be designed by integrating the local potency of certain region (Suratmi.
Laihat, & Santri, 2.
Consequently, the developed instructional media becomes more attractive and interactive for students and it is able to promote better understanding of learning topics.
According to the observation results, teacher mostly used textbooks and studentAos worksheet containing lesson topics and exercises as the primary instructional media for Mathematics lesson.
Unfortunately, the employed textbooks and studentAos worksheet presented unattractive lesson information.
Learning process did not maximally in developing Al Ibtida: Jurnal Pendidikan Guru MI.

Developing Module for Two-Dimensional CourseA student understanding about Mathematics.
In addition, what are presented in the textbooks and studentAos worksheet did not represent a social and cultural aspects around students.
Therefore, students considered Mathematics as an unattractive lesson to be studied.
resolving the explained issues, thus, it is important to develop a supplementary instructional media in the form of module for student.
Module is a learning material unit which is arranged in a linear sequence by using an understandable language and is adjusted to studentAos characteristics (Handayani, 2018.
Izzati & Fatikhah, 2.
, therefore, it promotes better lesson understanding, learning independence, and improves learning students motivation (Kuswono & Khaeroni, 2.
Furthermore, a module employed in the learning process promotes an alteration of studentAos way of thinking, even beliefs in a rational way, and ables to enforce a problem-solving ability for real-life context (Mahfar.
Aslan.
Noah.
Ahmad, & Jaafar, 2.
through learning activities and evaluations to measure studentAos understanding (DeWitt & Siraj, 2.
Thus, through the use of module, students are able to understand the lesson and perform a mathematical problemsolving.
Geometry is a a branch of Mathematics concerned with shapes, lines, points, spaces and also deals with how to connect certain form and pattern such as angle, length, width, and volume (Biswas.
Dumitrescu, & McKay, 2020.
Yang & Wang, 2.
Geometry lesson aims in studying a property of shapes and spaces, drawing a various forms of shape (NurAoaini.
Harahap.
Badruzzaman, & Darmawan, 2.
and it aims in enforcing studentAos critical thinking as well as responsibility in completing the assignments (Verner.
Massarwe, & Bshouty, 2019.
Wares & Elstak, 2.
Geometry lesson is taught in every educational degree, starting from elementary to senior high school.
It usually correlates with the surrounding phenomena and environment of students, therefore, the students are able to solve the problems related to geometry such as square, rectangle, and triangle (Safrina.
Ikhsan, & Ahmad, 2018.
Yi.
Flores, & Wang, 2.
In learning geometry, students are invited to learn and understand the surrounding stuffs that could be related with the geometry concept and it could also be correlated with the cultural values.
Culture constitutes an action, behavior, system, idea, human work, language, symbol, or even a myth within certain community and it plays a role as a cultural heritage within certain community (Abdullah, 2017.
Supiyati.
Hanum, & Jailani, 2.
Culture is closely related to the community identity such as how to dress, how to behave, how to farm, create, and how to solve problem using mathematical concept in the real-live situation (Muhtadi.

Developing Module for Two-Dimensional CourseA is important to connect it with the cultural values attached to students.
This is commonly called as ethnomathematics (Aikpitanyi, 2.
Ethnomathematics constitutes a concept and practice related to the common mathematical activities in school such as calculating, measuring, and weighing that are connected with historical concept.
This approach promotes that different thinking patterns could also generate a mathematical form (Hardiarti, 2017.
Kalinec-Craig.
Prasad, & Luna.
Zayyadi, 2.
In addition.
Ethnomathematics allows students to learn about the development of certain cultural community which becomes a fundamental element by understanding, interpreting, and connecting the cultural reality (Cimen, 2014.
Owens, 2.
In addition, it allows students to understand human condition related to cultural aspects in a natural way (Davis, 2.
, thus students could have a critical thinking systematically (Imswatama & Lukman, 2.
Mathematical concept within a cultural frame around the community or within a historical heritage should be preserved.
Thus, both Mathematics and Culture could be connected.
Several previous studies developed an instructional media for geometry lesson.
One of them was an instructional media containing a two-dimensional lesson by employing effective problem-solving exercises to improve the students ability in solving mathematical problem (Annisah, 2.
Then, one previous study developed an instructional media in the form of module by using CTL approach to facilitate students in acquiring a Mathematics concept independently (Yuniasih & Wahyuningtyas, 2.
Mathematics could be integrated with a cultural aspect.
In addition, the emphasize on the cultural aspects could be enforced as one approach to introduce a culture to students (Sunzuma & Maharaj, 2.
through informal learning method to develop the relationship between cultural aspects and mathematical ability (Prieto.
Claeys, & Gonzylez, 2.
An innovation based on the cultural aspects could be taken as a strategy to reduce the problems within conventional learning (Aikenhead, 2.
Previous studies also provided an example about a cultural aspect such as a traditional housing from the tribes around Indonesia, particularly a traditional housing of Papuan such as Rumah Kaki Seribu.
It could take as one example for explaining a triangle concept (Haryanto.
Nusantara.
Subanji, & Rahardjo, 2.
Furthermore, this could also enable students to explore cultural elements within the architecture of traditional building, for example a Sasak traditional architecture in Lombok Island such as a housing called Bale, worshipping building called Masjid, rice barn called Sambi (Supiyati et al.
, 2.
There is a need for innovation in the development of mathematics media.
It is associated with other regional cultures in Indonesia.
In this study, mathematics teaching topic will be developed in the form of Al Ibtida: Jurnal Pendidikan Guru MI.

Semmel, & Semmel, 1.
The stage of defining explained the analysis results about studentsAo responses in the learning process, the learning instrument used in the classroom, the identification of studentAos basic competences in Mathematics subject, and the development of studentAos cognitive level.
terms of instructional materials, it required a supplementary instructional media that is connected with the real-life context in the form of self-contained and user-friendly media.
means that the instructional media should be designed systematically and should employ an understandable language (Izzati & Fatikhah, 2.
Based on the results, thus it is important to develop independent instructional media for students.
The following stage was designing.
In this stage, the researchers designed the module starting from the cover, guidelines, main lessons that were completed with additional knowledge or information, studentAos exercises and evaluation tests along with the discussion and assessment.
