The model consisted of four development stages, namely define, design, develop, and disseminate. The research instruments were validation sheets, practicallity sheets, and learning achievement tests. The data were analyzed by grouping the data based on the product qualification and then calculations were made to obtain mean scores classified into categories in the Likert scale assessment. The results of the study are a product in the form of mathematics learning kit for SMK using the scientific approach oriented to students' mathematics learning achievements and communication skills, consisting of lesson plans, student worksheets, and learning achievement tests. Through the product validation stage, the lesson plans are considered to be valid. The product is very practical, and the results of the mathematics learning achievement and communication skill tests show that the product is effective. The developed product is valid, practical, and effective, and is appropriate to be used in classroom.Keywords: learning kit, scientific approach, mathematics communication skills
