The purpose of this study was to describe the results of the development of problem solving-based mathematics learning tools to train the creativity of students on estimating the amount and difference of two fractions in grade IV SD Khadijah. The development of learning tools in this study uses the Thiagarajan 4D model which is modified into 3D, namely the define stage, the design stage, the development stage. Learning tools developed include RPP, LKPD, and TKPD. The instruments used were the learning device validation sheet, the teacher and student activity observation sheet, the student's creativity test, and the learning outcome assessment. After the data were analyzed descriptively, the results of the study were as follows: the average value of the RPP was 3.79, the validity value of the LKPD was 3.50, and the results of the TKPD validation could be used with minor revisions. So that the learning device is said to be valid. The teacher's activities in implementing problem-solving learning have been good because all the learning steps in the lesson plan have been carried out. The activities of students while participating in learning at meeting 1 and meeting 2 have increased. With an increase in the activity of students it means that students are active in participating in problem solving-based mathematics learning. The students' creativity test was given two tests, namely before and after problem-solving based learning. The results of the creativity tests of students before and after problem solving based learning were 37.8% and 57.9%. Thus, the creativity of students has increased significantly after using problem-solving based learning tools.

Keywords : Problem solving based learning, creativity, estimation of the number and difference of two fractions
