Functional thinking is focused on the relationship between two or more variant quantities which can be represented by using natural language, tables, graphs, and algebra. Representation is the way that students use to find solutions and express ideas or thought of problems encountered. There are several kinds of representations that can be used in functional thinking, for example verbal, algebraic, numerical, images, graphics, etc. The aim of this study is to describe the use of students’ representations in functional thinking. This study belongs to qualitative descriptive research. Research subjects amounted to 45 students of Senior High School. The instruments used in this research were problem solving and interview. The results showed that students use verbal, numerical, algebraic, and image representations in their functional thinking. Nevertheless, students are more dominant on using algebraic representations. © 2019, Blue Eyes Intelligence Engineering and Sciences Publication. All rights reserved.
