The purpose of this study is to examine the errors and difficulties of student when representating irrational number on the number line. In order to achieve this purpose, we collected student’s errors and difficulties through task-based interview with high school students who learned irrational numbers. Furthermore, we conducted additional interview to help students. As a result, we found that placing a student's generated geometric representation on the number line is a complex process that includes concepts such as a sense of the number on number line, determining directionality for signs, and parallel movement. Therefore, teachers need to use an appropriate visual mediators when teaching irrational numbers.
