This study employed a qualitative approach with a phenomenological research design. Three junior high schools in Pekanbaru, Riau, were used as research location, with 18 students participating. This study's data collection methods included arithmetic thinking to algebraic thinking transition representation tests, student interviews, and observation sheets in the form of field notes. The research findings in this study are based on five characteristics of the representation of the transition from arithmetic thinking to algebraic thinking. Overall, seventh grade junior high school students represent the transition from arithmetic to algebraic thinking by; (1) understanding the meaning of the equal sign symbol as a relational, operational-relational, and operational symbol; (2) understanding commutative and distributive properties is still lacking because students believe that the number structure relating with commutative and distributive properties is something to be calculated with; (3) applying basic operations in accordance with the order of operations; (4) interpreting algebraic letters as unknown and generalized numbers, while some students are unable to form algebraic expressions; and (5) creating a variety of mathematical representations, such as equations, images, number tables, and number lines. %Z Link Google Scholar: https://scholar.google.co.id/citations?user=J_Sog48AAAAJ&hl=en ID SINTA Dosen Pembimbing Tatang Herman: 0011106206 Siti Fatimah: 0023086806
