The LKS(worksheets) that are used in schools generally only contain questions, so they have not helped the students in constructing mathematical knowledge. Therefore, constructivist-based LKS is developed for learning mathematical knowledge. This study aimed to develop constructivist-based LKS on the subject of Polyhedronand to see the validity of the produced worksheets. This research was a research development using a 4-D model. This model consists of the stages of define, design, and disseminate. Data collection was carried out through validation and trial of the developed LKS. Validation was carried out by 3 validators who are experienced in their fields and the trials were conducted on grade seventh of SMP Negeri (Public Junior High School) 1 Kubung to determine the practicality and effectiveness of the LKS. This study produced constructivist-based LKS on the subject of Polyhedron. The validity of the LKS was categorized as very valid. Validity test that was carried out consisted of several aspects, namely aspects of content / material, form / presentation and language / legibility. The validation results showed that theLKS was very valid with an average value of 3.42. The practicality test results in aspects of the attractiveness of the LKS to student interest, ease of use and content, and the efficiency of time showed this constructivist-based LKS was very practical for students and teachers with an average value of 89.14% and 79.25%.
