The goal of the present study is to create joyful atmosphere in mathematics learning by implementing Kopermatik (the Box Games Realistic Mathematics), a set of mathematical teaching aids that are equipped with realistic mathematics worksheets and they are designed in the form of the game. Kopermatik development is an attempt to enrich the variety of aids and math games, for which its implementation in schools is to create a joyful atmosphere. The population of this research is students of SDN 44 Ampenan the academic year 2009/2010 (high grade classes) and 2010/2011 (low grade classes). The classroom setting uses cooperative model, four students in one group, who learn while playing Kopermatik aids and fill in worksheets that contain developing concepts and realistic problems. Based on a questionnaire filled out by teachers who are involved in the study, all teachers feel good, easy and helpful to learn to use Kopermatik aids. Students have good attitude and appreciation by learning using Kopermatik, where 97.1% students enjoy learning with Kopermatik, 93.1% enjoy learning in groups, and 81.2% of students feel confident to be in front of the class. The effectiveness of learning with Kopermatik is high, i.e the understanding of the concept of learning outcomes achieved a score of 82.5, while the ability to solve realistic problems reaches a score of 76.4. These results indicate that the implementation of Kopermatik for all grades of students in SDN 44 Ampenan can make students more active, creative and joyful in mathematics learning.udKeywords: Kopermatik aids, understanding concepts, realistic problems, joyful atmosphere, elementary school ud
