The respondence of this research are 37 students of seventh grade at SMP Negeri 6 Sekayu. The instrument used for this research is test of open ended problems. All data have been collected was analysed qualitatively. The results show that: (1) This research produces open ended problem about fraction number for students of VII grade which are valid and practical. The validity was judged  by validator, where the all validators state that the instrument have been valid based on the content, construct and face. The validity was also judge by validator in the small group. The practicality was shown by the result of validators, which most of students could solve the open-ended problems.
