In the new guidelines to be implemented from 2020, the programming education is introduced from the elementary school stage. But, on implementation of the programming education, it is said that there are various problems. The purpose of this research is to develop a robot that draws an arithmetic [5th grader] regular polygon in elementary school without using visual programming. Specifically, by inserting three blocks into the top of the robot, some regular polygons can be written. These three blocks set the size of the interior angles of some regular polygons, the number of repetitions, and the length of the sides. In order to evaluate the robot, we showed a video of the robot in action and several questionnaires were conducted to the elementary school teachers.
