The research design uses Research and development (R&D) with a 4-D model (Four-D Models). The results of this study 1) Design of teaching materials for mathematics booklets based on Realistic Mathematics Education (RME) for class V SD, 2) Feasibility Test for Realistic Mathematics Education (RME) based mathematics booklets for class V Elementary School Students, 3) Test the effectiveness of Realistic Mathematics Education (RME) based mathematics booklets) class V Elementary School Students keywords: literasi numerasi, bahan ajar booklet matematika, realistic mathematics education (RME) INTRODUCTION Education is a conscious and planned effort to create a learning atmosphere and learning process so that students actively develop their potential to have religious spiritual strength, self-control, personality, intelligence, noble character, and the skills needed by themselves, society, nation and state (Law No. .20 of 2003). Mathematics is one of the subjects taught at every level of education. By studying mathematics, it prepares students to be able to compete by using a creative, innovative and imaginative mindset (Utami, Mukhni, & Jazwinarti, 2014: 7). Based on data from the National Council of Teachers of Mathematics/NCTM Ratnaningsih (2008: 129) there are five standard processes for students in acquiring and using mathematical knowledge, namely: problem solving, reasoning and proof (reasoning and proof), communication (communication), connection (connection), and representation (representation). By paying attention to this, it is necessary to develop students' thinking and reasoning processes in learning mathematics for the self-development of students in the future (Efuansyah and Reni Wahyuni, 2018). Mathematical literacy is one of the important components that students need to be able to successfully solve problems with the ability to analyze, give reasons, and convey ideas effectively, formulate, solve and interpret mathematical problems in various forms and situations. Activating student learning in learning activities is one way to animate and train student memory so that it works to develop optimally (Marno, 2018).
