Student worksheets are one of the student assignment guidelines that provide students opportunities for developing their mathematical problem-solving abilities. This study aimed to develop the determinant and inverse matrix student worksheets based on problem-based learning. This study was development research using the ADDIE model, consisting of five stages. This study’s subjects were SMA X (n=28) in Imogiri, Yogyakarta. Data collection was carried out through questionnaires. The material and media experts assess the validity of student worksheets using a questionnaire. Whereas students assessed the teaching material practicality. The development of students’ worksheets based on problem-based learning reached the validity and practical criteria. The validity of the students’ worksheets is based on the assessment results by material experts with an average score of 77, which means the students’ worksheets belong to the "very good" category. The same result was related to the practicality of the students’ worksheets based on media experts’ assessment results, which show an average score of 64, which means the students’ worksheets belong to the "very good" category. In line with that, the average score of students’ responses is 79.83, which indicates that "good" assessment for students’ worksheets is used or belonging reaching the practicality criteria of development product.
