This research is conducted due to the low Mathematical Problem Solving Ability (KPMM) of students and the limited learning devices that didn’t fulfill the demands of the 2013 Curriculum. Based on the analysis and interview conducted by the researcher, it was found out that the learning kits used by the teachers at school was not referred to and in accordance with 2013 Curriculum. In this regard, this study aims to produce a valid and practical mathematics learning devices that facilitate students' mathematical problem solving abilities. The development of learning devices includes developing syllabus, lesson plans, and student workbook (LKPD).
This type of research is research and development. The development model used is ADDIE, namely Analysis, Design, Development, Implementation, and Evaluation. In the Analysis stage, the researcher conducted needs analysis, student analysis and teaching material analysis. At this stage the researcher examines the curriculum, learning tools, the results of students' problem solving abilities and the scope of the material. In the Design phase, the researcher designed learning tools in the form of a syllabus, lesson plans, student workbook (LKPD), validity data instruments and practicality data instruments. At the development stage, the researcher developed learning tools for six meetings, namely: 1) The surface area of the tube; 2) Tube volume; 3) Cone surface area; 4) The volume of the cone; 5) Surface area of the sphere; 6) Volume of the ball. Then the learning tools that had been developed based on the design plan were validated by three validators. Validity data were obtained from the validation sheets which were assessed by the validator. Learning tools are valid if the minimum level of validity achieved based on the results of the validator's assessment is more than 70%. The validity of the syllabus is 94.13% with a very valid category, the validity of the lesson plans is 92.36% with a very valid category, the validity of the student workbook (LKPD) is 92.09% with a very valid category. Thus, the learning device developed is feasible to be tested as a learning device on curved side space with revisions.
Implementation stage, this stage tested the developed learning tools that had been given to ten students to obtain practical data. Learning tools are said to be practical if the percentage level of practicality is more than 70%. The activities contained in each student workbook (LKPD) can facilitate students' mathematical problem solving abilities using the guided discovery model. At the stage of

formulating problems, students were presented with contextual problems related to the material being studied. Then the students observed the problems. At the stage of formulating the hypothesis, the students were directed to write temporary answers to the problems that had been presented in the previous stage. At the stage of collecting data, students were directed to collect data that had been presented in the problem and constructed the knowledge that had been previously possessed in obtaining the concepts. At the stage of testing the hypotheses, the students were directed to process the data to obtain conclusions. At the stage of drawing conclusions, the students were directed to conclude the material that had been studied. The results of the readability of learning tools in the limited trial of the student workbook (LKPD) were 90% in the very practical category. Then the learning devices were revised according to the suggestions from students. At the Evaluation stage, the researcher revised the learning devices according to the input and suggestions from the validator and students.
Thus, it can be concluded that the learning devices that have been developed are very practical to facilitate the mathematical problem solving abilities of students in the subject of curved side space for class IX SMP.
