This development research is motivated by mathematics teaching materials in class VII UPT SMP Negeri 14 Bandar Lampung which have not fully facilitated students towards mathematical communication skills. The teaching materials used do not provide opportunities for students to find mathematical concepts independently and do not provide opportunities for students to express their own opinions. The purpose of this research and development is to: 1) develop and determine the feasibility of Learning Cycle 5E-based LKPD to facilitate students' mathematical communication skills on the material of rectangular and triangular flat shapes in class VII SMP in terms of validity, attractiveness, and practicality as teaching materials, and 2) determine the effectiveness of using Learning Cycle 5E-based LKPD to facilitate students' mathematical communication skills on the material of rectangular and triangular flat shapes. This type of research is Research and Development (R&D) with the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model. The results of LKPD validation for material experts obtained a value of 4.34 with "Valid" criteria, media expert validation of 4.29 with "Valid" criteria, linguists of 4.79 with "Valid" criteria, the results of students' responses obtained a value of 4.58 with "Interesting" criteria, and from the response of educators obtained an average value of 4.47 with "Practical" criteria. After using the Learning Cycle 5E-based LKPD developed, learning completeness through the trial test of students on mathematical communication skills reached a clasical completeness of 87%. These results state that the Learning Cycle 5E-based mathematics LKPD for class VII SMP is suitable for use as teaching material.
