This study aims to develop mathematical learning devices The aim is for students to be able to communicate ideas with symbols, tables, diagrams, or other media to clarify the state of a mathematical learning problem called mathematical communication skills. it is necessary to develop a device with an approach to improve the student’s mathematical communication skill. The CTL approach can help students to create mathematical communication skills. Because with CTL, students can find the subject learned by linking it to real-life situations so that they can apply it in everyday life. The indicators of communication capabilities developed are Illustrating mathematical ideas, using symbols/notations and mathematical operations, selecting and writing relevant mathematical strategies and giving conclusions at the end of the answer. The development model used is the Plomp model, which consists of three phases. First is the initial investigation phase, the second is the development or prototype development phase, and the third is the evaluation phase.
