摘要：This study aims to: 1) to determine the increase in creative thinking skills of students who are taught using learning tools developed using the discovery learning model; 2) to determine the increase in the problem-solving abilities of students who are taught using learning tools developed using the Discovery Learning model; 3) to determine the validity, practicality and effectiveness of learning tools developed using the discovery learning model. The subjects of this study were VIII grade junior high school students of Al-Hikmah Medan in the 2020/2021 academic year. The results showed that: 1) the mathematical creative thinking ability of students using learning tools with the discovery learning model increased in terms of: The average posttest score of the first test was 76.88, increased to 80.94 in the second test and experienced an increase in stage the spread of 88.75 and the N-Gain test I of 0.30 in the medium category increased to 0.33 in the medium category in the second test and at the distribution stage it increased to 0.62 in the moderate category; 2) the mathematical problem solving ability of students using learning tools with the Discovery Learning model increased in terms of: the average posttest score of the first test was 76.88, increased to 81.19 in the second test and experienced an increase in the distribution stage of 84.38 and N-Gain in the first test of 0.31 in the moderate category, increasing to 0.33 in the medium category in the second test and at the distribution stage, increasing to 0.42 in the moderate category; 3) the learning tools developed with the Discovery Learning Model have met the criteria of validity, practicality, and effectiveness.
