This study aims to produce a valid and effective learning tool that is impactful towards students’ mathematical problem solving ability by using number heads together type cooperative learning model. The study developed both lesson plan ((known as RPP) and students' worksheets (known as LKPD) by using the Plomp development model. The research focuses on testing the effectiveness of the learning tool. The instruments used in this study are validation sheets and problem-solving skills tests. The result of the survey shows that RPP and LKPD were valid and effective.
